Abstract:
SummaryThe DELTA parallel robot, designed by an EPFL (Ecole Polytechnique Fédérale de Lausanne) research team, is a mechanical structure which has the advantage of parallel robots and ease of serial robots modeling. This paper presents solutions for a complete modeling of the DELTA parallel robot (direct and inverse kinematics, inverse statics, inverse dynamics), with few arithmetic and trigonometric operations. Our method is based on a satisfactory choice of kinematic parameters and on a few restricting hypotheses for the static and dynamic models. We give some details of each model, we present some computation results and we put the emphasis on some particular points, showing the capabilities of this mechanical structure.

Abstract:
In this work, we propose the method for the investigation of stochastic vibrations of deterministic mechanical systems represented by axially symmetric spherical shells. These structure members are widely used as sensitive elements of pressure measuring devices in various branches of measuring and control industry, machine design, and so forth. The proposed method can be easily extended for the investigation of shallow spherical shells, goffer-type membranes, and so on. The so-called charts of control parameters for a shell subjected to a transversal uniformly distributed and local harmonic loading force and resistance moment are constructed. The scenarios of the transition of vibration of shallow-type system into chaotic state are investigated with the use of the theory of differential equations and the theory of nonlinear dynamics. The method of the control of chaotic vibrations of flexible spherical shells subjected to a transversal harmonic load through a synchronized action of either harmonic resistance moment or force is proposed, illustrated, and discussed.

This paper replaces increasing product variety with quality upgrading in the Romer model [Romer, Paul M., Journal of Political Economy 98 (1990), S71–S102]. We show that the range of parameters for which a steady state exists can be divided into two subspaces with well-behaved comparative statics and saddle-point dynamics in one subspace, but with “perverse” comparative-statics properties and either equilibrium indeterminacy or instability in the other subspace. These results for the closed economy can also be used to characterize the dynamics of the M-country open-economy version of the model.

Abstract:
The subject of this work is the problem of describing the dynamic behavior of the price in the market of one product. The typical balance of interaction of supply and demand functions depending on the price is considered. The dynamic model of price evolution is based on the assumption that the demand function at a given time depends on the supply function at all previous points in time, i.e. there is a process with an aftereffect. The core of the integral transformation is a characteristic of the second order, which can initiate periodic regimes in price variables. The aim of the work is to synthesize a mathematical model of price changes in the market of one product and study the stability of its equilibrium states with the manifestation of the structure of marginal cycles. The task of the study is to demonstrate the degree of connection between the problem of stability of equilibrium and the problem of obtaining fruitful results in comparative statics. This duality is the principle of conformity of P. Samuelson. The basic mathematical model of the studied process of price dynamics is a system of two nonlinear differential equations of the first order. The research methods are the nonlinear theory of analysis of dynamical systems, the mathematical theory of stability of systems of differential equations, the conceptual apparatus of analysis of typical bifurcations of birth (death) of the boundary cycle, known as the Andronov-Hopf bifurcation. As a result of a detailed analysis of the properties and parameters of self-oscillating modes, a double cycle is revealed, i.e. there is a fact of coexistence around the equilibrium state of stable and unstable limit cycles. Subsequent mathematical transformations prove that the line of demarcation of these two cycles is completely determined by the static parameters of the studied system, which illustrates the mechanism of action of the principle of conformity of P. Samuelson. Conclusions: on the example of the functioning of the labor market, a comprehensive analysis of the stability of two positive equilibrium states, which characterize the effects of substitution and income. Computer simulations are used to perform computational experiments that demonstrate self-oscillating modes of price changes. As a result of the analysis of the obtained numerical results, it is possible to draw a conclusion about the stability of the limit cycle in the vicinity of the equilibrium state, which corresponds to the substitution effect.

Abstract:
Selecting the optimal parameters for wet steam accumulator of steam-powered catapult is an important task, due to launching safety. There is no literature on the topic of the parameters optimization for wet steam accumulator of steam-powered catapult. The genetic algorithm (GA) was used to determine the optimal wet steam accumulator in this article. The sink-off-the-bow (SOB), angle of attack and rate of climb were used to create the objective function. The multi-objective optimization can be converted to single-objective optimization, which is subject to angle of attack and rate of climb. Moreover, the simulation model of the steam catapult system was built by creating a thermodynamics model of steam-powered catapult, a mathematical model of traction release device, a statics model of tensioning, a statics model of full takeoff power, a mathematical model of catapult force build-up with holdback, a model of release, a dynamics model of power stroke, a dynamics model of free deck run and a dynamics model of fly away. Finally, the optimal combination of the wet steam accumulator was obtained via numerical simulation. The GA method can effectively find the optimal parameters of wet steam accumulator, and its optimized parameters can increase the safety of catapult launch process.

Abstract:
A lattice design of a cloak for full two-dimensional elasticity is suggested when the background continuum is isotropic with Lamé parameters (λ, μ ) satisfying μ ≤ λ. The lattice is polar in the sense that it elastically resists rotations; and is degenerate meaning it admits a stressless collapse mechanism. These characteristics are attained through the use of appropriately distributed restoring torques in conjunction with hinge-like spring-mass contacts. Thus, the lattice is proven to exhibit a rank-3 elasticity tensor lacking the minor symmetries. Accordingly, it rigorously adheres to the form-invariance requirements of the transformation method under the Brun–Guenneau–Movchan gauge. The cloak is numerically tested in statics and in dynamics under pressure and shear incident waves and shows satisfactory performance. Finally, a theoretical generalization extends the design to three dimensions and to arbitrarily anisotropic backgrounds so as to enable cloaking as well as other transformation-based static and dynamic field manipulation techniques in these cases.

Abstract:
Proper foam statics index can give essential indications on foam dynamic behavior in porous media. In this paper, the statics characteristics are investigated through air-flow method for foam generated with Sodium Dodecyl Sulfate (SDS) surfactant. Parameters of foam height, foam half period time are recorded for various gas phases, surfactant concentrations and injecting gas flow rate, and foam morphology are also visually monitored. It is found the N2 generated foam has better characteristics on foam height, while poorer characteristics on foam half-time period compared to air and CO2 foam. Widely employed Foam Composite Index (FCI) is no longer suitable for predicting foam dynamic behavior, a Foam Index for predicting Dynamic Behavior in Porous Media (FIDBPM) is therefore defined to predict properly the foam transient propagation process in porous media.

The paper aims at identifying metaphorization of quantitative lexemes as a basic means to form quantifiers. The research objective is to develop a classification of qualitative parameters for the Italian and French quantifiers. In particular, a structural approach is used, based on such methods of material analysis as the comparative-typological method, contextual analysis, and the method of lexicographic definitions. The authors pay attention to the identification of qualitative parameters, a set of properties that characterizes the quantifiers under study. All identified parameters are analysed in a comparative manner. The authors have pointed to such parameters as deicticity, statics / dynamics, connotation, homogeneity / heterogeneity, simultaneity / sequence.

Abstract:
In power generation from solid fuel such as coal-fired power plants, combustion efficiency can be monitored by the loss on ignition (LOI) of the pulverised fuel. It is the role of the pulveriser-classifier combination to ensure pulverised fuel delivered to the burners is within the specified limits of fineness and mass flow deviation required to keep the LOI at an acceptable level. However, government imposed limits on emissions have spurred the conversion of many coal fired power plants to convert to the use of Low NOx Burners. To maintain good LOI or combustion efficiency, the limits of fineness and mass flow deviation or inter-outlet fuel distribution have become narrower. A lot of existing pulveriser units cannot operate efficiently within these limits hence retrofits of short term solutions such as orifice balancing and classifier maintenance has been applied. The work performed in this thesis relates to an investigation into coal classifier devices that function to control fineness and inter pipe balancing upstream of the burner and downstream of the pulverisers. A cold flow model of a static classifier was developed to investigate the flow characteristics so that design optimisations can be made. Dynamic similarity was achieved by designing a 1/3 scale model with air as the continuous phase and glass cenospheres of a similar size distribution as pulverised fuel, to simulate the coal dust. The rig was operated in positive pressure with air at room temperature and discharge to atmosphere. The Stokes number similarity (0.11-prototype vs. 0.08-model) was the most important dimensionless parameter to conserve as Reynolds number becomes independent of separation efficiency and pressure drop at high industrial values such as 2 x 10 4 Hoffman, 2008). Air-fuel ratio was also compromised and an assumption of dilute flow was made to qualify this. However, the effect of air fuel ratio was ascertained by its inclusion as an experimental variable. Experiments were conducted at air flow rates of 1.41-1.71kg/s and air fuel ratios of 4.8-10 with classifier vane angle adjustment (30°- 60°) and inlet swirl umbers (S) of 0.49 – 1. Radial profiles of tangential, axial and radial velocity were obtained at several cross sections to determine the airflow pattern and establish links with the separation performance and outlet flow balance. Results show a proportional relationship between cone vane angle and cut size or particle fineness. Models can be derived from the data so that reliable predictions of fineness and outlet fuel balance can be used in power stations and replace simplistic and process simulator models that fail to correctly predict performance. It was found that swirl intensity is more significant a parameter in obtaining balanced flow at the classifier outlets than uniform air flow distribution in the mill. However the latter is important in obtaining high grade efficiencies and cut size. The study concludes that the static classifier can be further improved and retrofit-able solutions can be applied to problems of outlet flow imbalance and poor fineness at the mill outlets.

Abstract:
Abstract This thesis presents computational studies of both the static and dynamic parameters of the nuclear magnetic resonance (NMR) spectroscopy of gaseous xenon. First, state-of-the-art static magnetic resonance parameters are computed in small xenon clusters by using methods of quantum chemistry, and second, time-dependent relaxation phenomena are investigated via molecular dynamics simulations at different experimental conditions. Based on the underlying quantum and classical mechanics concepts, computational methods represent a procedure complementary to experiments for investigating the properties of atoms, molecules, clusters and solids. Static NMR spectral parameters, chemical shift, shielding anisotropy and asymmetry parameter, nuclear quadrupole coupling, and spin-rotation coupling, are calculated using different electronic structure methods ranging from the uncorrelated Hartree-Fock method to correlated second-order Møller-Plesset many-body perturbation, complete/restricted active space multiconfiguration self-consistent field, and to coupled-cluster approaches. The bond length dependence of these properties is investigated in the xenon dimer (Xe2). A well-characterized property in experimental NMR, the second virial coefficient of nuclear shielding, is theoretically calculated by a variety of methods and convincingly verified against experimental findings. Here, it is mandatory to include effects from special relativity as well as electron correlation. As a side result, a purely theoretical potential energy curve for Xe2, comparable to best experimental ones, is calculated. A pairwise additive scheme is established to approximate the NMR properties in differently coordinated sites of xenon clusters Xen (n = 2 - 12). Especially the pairwise additive chemical shift values are found to be in close agreement with quantum-chemical results and only a small scaling factor close to unity is needed for the correct behavior. Finally, a dynamical magnetic resonance property, the experimental nuclear spin-lattice relaxation rate R1 of monoatomic Xe gas due to the chemical shift anisotropy (CSA) mechanism is validated from first principles. This approach is based on molecular dynamics simulations over a large range of temperatures and densities, combined with the pairwise additive approximation for the shielding tensor. Therein, the shielding time correlation function is seen to reflect the characteristic time scales related to both interatomic collisions and cluster formation. For the first time, the physics of gaseous xenon is detailed in full in the context of CSA relaxation.

Abstract:
This thesis contributes to the understanding of one dimensional mechanical lattice structures. Structures formed from freely pin jointed rigid links with either vertical or torsional springs at the pivots, or both, are studied under the in uence of an axial load. These studies fall into three parts: static behaviour of a `simple' mechanical system with only vertical springs, dynamic behaviour of this `simple' system, and static behaviour of a compound mechanical lattice with both vertical and torsional springs. The �rst part uses ideas from the �eld of discrete mechanics to derive several discrete boundary value problems that model the static equilibrium states of the `simple' mechanical lattice. This application of discrete mechanics allows us to better understand the relationships between the mechanical system and the discrete boundary value problem used to model it. The resulting discrete boundary value problem is studied in detail and interesting complex behaviour is observed. The study of the dynamic behaviour of the `simple' mechanical lattice concentrates on the existence and stability of time periodic spatially localised solutions called discrete breathers. Discrete breathers are found to exist and to be stable. Also, related solutions called phonobreathers are found to exist and, although the exact phonobreather solutions are unstable, interesting nonlinear dynamic behaviour is observed close to the unstable solutions. Finally, the static behaviour of a new compound mechanical lattice, a discrete version of the strut on a linear foundation, is studied in Chapter 6. We see how the behaviour of two simpler mechanical lattices is manifested in this compound lattice, before presenting analytic and numerical results on the primary, static, bifurcations of this compound lattice. The localised behaviour of the most physically relevant static equilibrium states is also investigated. Extensions to the discrete boundary value problem methods of the earlier chapters are also discussed.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2004.
Includes bibliographical references (p. 95-101).
The conversion of chemical energy into mechanical forces that powers cell movements is a ubiquitous theme across biology. The acrosome reaction of Limulus sperm is a simple example of such a dynamical transformation where a 60 [mu]m-long crystalline bundle of actin filaments, tightly cross-linked by actin bundling protein scruin, straightens from a coiled conformation and extends from the cell in five seconds. This spring-like mechanism represents a third type of actin-based motility that is distinctly different from the better known polymerization or myosin-driven processes. To identify the basis and mechanism for this movement, we examine the possible sources of chemical and mechanical energy and show that the stored elastic energy alone is sufficient to drive the reaction. We also provide an estimate of the maximum force generated during the uncoiling by stalling the bundle using an agarose gel. Finally, we provide a simple mathematical model that rationalizes the dynamics of uncoiling. Motivated by the very stiff cross-linking in the bundle induced by scruin, we next turn to a model system of scruin mediated cross-linked actin networks where the elastic response is dominated by the properties of actin. While the biological significance of the actin cross-linking proteins is well documented, little is known about how bundling and cross-linking quantitatively affects the microstructure and mechanical properties of actin networks. We quantify the effect of scruin on actin networks using imaging techniques, co-sedimentation assays. multi-particle tracking (MPT), and bulk rheology and demonstrate how a simple entropic elasticity model for a semi-flexible polymer network explains the linear elastic regime of the actin-scruin network.

Abstract:
Wetting, which addresses either spontaneous or forced spreading of liquids on a solid surface, is a ubiquitous phenomenon in nature and can be observed by us on a daily basis, e.g., rain drops falling on a windshield and lubricants protecting our corneas. The study of wetting phenomena can be traced back to the observation of water rising in a capillary tube by Hauksbee in 1706 and still remains as a hot topic, since it lays the foundation for a wide spectrum of applications, such as fluid mechanics, surface chemistry, micro/nanofluidic devices, and phase change heat transfer enhancement. Generally, wetting is governed by the dynamic and static behaviors of the three-phase contact line. Therefore, a deep insight into the dynamics and statics of three-phase contact line at nanoscale is necessary for the technological advancement in nanotechnology and nanoscience. This dissertation aims to understand the dynamic wetting under a molecular kinetic framework and resolve the reconfiguration of liquid molecules at the molecular region of contact line. Water spreading on polytetrafluoroethylene surfaces is selected as a classical example to study the dynamic behaviors of three-phase contact line. To accommodate the moving contact line paradox, the excess free energy is considered to be dissipated in the form of molecular dissipation. As-formed contact line friction/dissipation coefficient is calculated for water interacting with PTFE surfaces with varying structures and is found to be on the same order of magnitude with dynamic viscosity. From an ab initio perspective, contact line friction is decomposed into contributions from solid-liquid retarding and viscous damping. A mathematical model is established to generalize the overall friction between a droplet and a solid surface, which is able to clarify the static-to-kinetic transition of solid-liquid friction without introducing contact angle hysteresis. Moreover, drag reduction on lotus-leaf-like surface is accounted for as well. For the first time, the concept of contact line friction is used in the rational design of a superhydrophobic condenser surface for continuous dropwise condensation. We focus on the transport and reconfiguration of liquid molecules confined by a solid wall to shed light on the morphology of the molecular region of a three-phase contact line. A governing equation, which originates from the free energy analysis of a nonuniform monocomponent system, is derived to describe the patterned oscillations of liquid density. By comparing to the Reynolds transport theorem, we find that the oscillatory profiles of interfacial liquids are indeed governed in a combined manner by self-diffusion, surface-induced convection and shifted glass transition. Particularly for interfacial water, the solid confining effects give rise to a bifurcating configuration of hydrogen bonds. Such unique configuration consists of repetitive layer-by-layer water sheets with intra-layer hydrogen bonds and inter-layer defects. Molecular dynamics simulations on the interfacial configuration of water on solid surfaces reveal a quadratic dependence of adhesion on solid-liquid affinity, which bridges the gap between macroscopic interfacial properties and microscopic parameters.

This project seeks to demonstrate routing optimization that would allow pedestrian and micromobility user groups to select and prioritize different route features according to their preferences. Through the creation of a routing demonstrator that considers both static and dynamic parameters in the form of pavement quality, elevation climb, travel time, and air quality, along with user-specified weights for their prioritization of each of these parameters, a number of routes were created and mapped to qualitatively compare against routes representing only a shortest path.

Abstract:
In this paper, we present new Pseudo-Rigid-Body (PRB) models for clamped-free cantilever beams and pinned-free compliant links for predicting natural frequency in dynamics analysis. In recent decades, PRB models have been extensively studied for predicting statics and kinematics of 2D or 3D beams subject to large deformation under tip loads. However, few studies focus on their accuracy for predicting dynamic analysis. Not like in statics and kinematics, the mass distribution of PRB model plays an important factor in dynamics of compliant beams. In this paper, we introduce mass property parameters to the PRB models. By comparing with the continuous model, we search for the optimal set of mass property parameters for minimizing the error of natural frequency. To demonstrate the procedure, we study two cases: clamped-free cantilever beams and pinned-free compliant links both have an end mass. The results show that the natural frequency of the optimized PRB model well agrees with that from the continuous beam model. The modified PRB model will significantly simplify the dynamics modeling in compliant mechanisms.

Abstract:
Dynamics software usage in the analysis of vehicles is becoming more prevalent in industrial settings. Multibody tools allow the user to put together a digital or virtual model of the vehicle before any physical prototype is built. The tools have now reached a level of sophistication that allows the same tests to be performed on the digital model as on the physical model. In the analysis of a vehicle a virtual model allows the user to analyze the vehicle’s performance in ride and comfort scenarios as well as in durability scenarios. Multibody tools also allow the user to perform design of experiments or trade-off studies in these scenarios by varying different parameters of the vehicle. However, to be of optimal usage in a design of experiments approach the solution times of the complex models must be short allowing larger parameter studies to be done quickly. In the analysis of many vehicles and in particular race cars only the vehicle’s limits in a turn or corner are needed. Limiting the vehicle analysis to cornering allows the multibody code to use steady-state analysis instead of a full dynamic simulation. Typically, multibody codes construct differential-algebraic equations (DAE) to form the equations of motion and then must use complex numerical analysis techniques to solve the DAEs. By making the assumption that the vehicle is in a corner the DAEs can be reduced to a set of algebraic equations, which can then be solved very efficiently by a statics solver. A statics solver by definition requires the velocities and accelerations to be zero, but in the cornering analysis of a vehicle this assumption can not be made. This paper will document the extensions necessary to convert the Virtual.Lab multibody statics solver into a steady-state solver it will then apply this steady-state solver to the cornering analysis of a full vehicle model.

Abstract:
Accurate knowledge of machine dynamics is required for predicting stability and precision in a machining process. Frequency response function (FRF) measurements need to be performed to identify the dynamics of the systems experimentally. This can be very time consuming considering the number of tool-tool holder combinations in a production facility. In this paper, methods for modelling dynamics of milling tool is presented. Static and dynamic analysis of tools with different geometry and material are carried out by Finite Element Analysis (FEA). Some practical equations are developed to predict the static and dynamic properties of tools. Receptance coupling and substructuring analyses are used to combine the dynamics of individual component dynamics. In this analysis, experimental or analytic FRFs for the individual components are used to predict the final assembly’s dynamic response. The critical point in this analysis is to identify the interface stiffness and damping between the tool and tool holder. The effects of changes in tool parameters and clamping conditions are evaluated. The predictions are verified by measurements.

Full text
Abstract:
A method for modeling the dynamics of industrial pumping systems is presented. The approach extends existing models for aero-engine like applications to capture dynamic features of interest in industrial, ground-based, applications. Those include the driver-driven (e.g., turbine-pump or compressor) interaction, the driver speed regulation subsystem, and their impact on stability. The method utilizes a lumped parameter modeling approach that involves developing and analyzing a set of nonlinear ordinary differential equations which describe the system dynamics. A model of a baseline industrial pumping system comprised of a turbine driving a process compressor is formulated first. Components in the compressor flow path include an inlet duct, a plenum, and a discharge valve. The resulting model captures the system’s instability onset point, the post-stall behavior, and the sensitivity to system parameters. Two non-dimensional groups are found to play a dominant role in characterizing the overall dynamics: the ratio of fluid compliance to fluid inertia on the compressor side (B-parameter), and the ratio of the mechanical inertia of the rotating assembly to the fluid inertia. Low values of the B-parameter have a strong stabilizing effect and are associated with high frequency surge oscillations. In contrast, low values of the mechanical to fluid inertia ratio have a stabilizing effect only in a limited region of the compressor operating range, and have little effect on surge frequency. For the baseline system considered in this study, stabilizing effects of these two ratios were observed at values less than 0.4 and 0.2 respectively. The baseline system model is then expanded to include a turbine speed controller. This allows examination of large transient events such as station shutdown and the phenomena of turbine hunting. It is found that the parameters of the turbine speed controller can affect the stability during such transients, but have little impact on the post-stall behavior.

Full text
Abstract:
Determination of pull-in parameters is vital in the design of electrostatically actuated microdevices. Moreover, it is important to devise some means to gain a control over the pull-in parameters in order to establish the customized microactuator design practice. In this paper, we analyze the influence of the beam geometry on the dynamic pull-in parameters of electrostatically actuated microbeams. Novel width functions are proposed for the microcantilever and the fixed-fixed beam, which smoothly vary the width of the microbeam along its length. We demonstrate the use of these width-functions by comparing six different microbeam geometries, three for cantilevered beam and three for fixed-fixed beam along with their constant width rectangular counterparts. All configurations are analyzed using an energy technique which gives an upper bound on the critical amplitude of the microbeam displacement, which is subsequently used to extract a lower bound on the applied voltage at the point of dynamic pull-in instability. For every case, a comparison is made between the static and the dynamic pull-in parameters. Results indicate a greater pull-in range for concave beam geometries, while the convex geometries exhibit a reduction in the pull-in range. Actuation voltage requirement is found to be proportional to the increase in the travel range. In all cases, the dynamic pull-in displacement is found to be greater than the static pull-in displacement, while the dynamic pull-in voltage is found to be less than the static pull-in voltage.

Full text
Abstract:
Transient phenomena associated with gas recycling during compressor emergency shutdown (ESD) have been studied both experimentally and numerically, A scaled-down laboratory test rig has been constructed to study the influence of various underlying parameters on ESD operation. Three different configurations representing different design scenarios were tested. The first configuration has a long recycle system with a volume capacitance representing an air cooled heat exchanger in the recycle loop, and the recycle valve located close to the discharge side. The second one is the same as the first except the recycle valve placed close to the suction side. In the third configuration, the cooler capacitance was removed from the recycle loop and the piping capacitance on the discharge side was further reduced. Shutdown tests were carried out from different steady state initial conditions varying the recycle valve opening time, and the synchronization time between the compressor ESD signal and valve opening signal. Numerical simulations based on the solution of the full one-dimensional conservation equations using the method of characteristics were also conducted for the above configurations. Good agreement was obtained between measurements and simulation results. Numerical simulations were used to analyze other cases which were not investigated experimentally, to further investigate the interaction between equipment and flow parameters. Results indicate that the valve prestroke time is more crucial than the stroke time and that it should be made short to avoid surging the compressor during ESD. Locating the recycle valve as close as possible to the suction or discharge of the compressor helps reduce unit surge during shutdown.

Abstract:
Complex process such as heat transfer, mass transfer and flow is occurring in the condenser, simulation analysis is an effective method of studying its dynamical character. Conventionally, simulation of condenser is modeled basing on thermal system static, the content and depth of research is not enough. Aiming at understanding its transient character deeply, condenser modeling is carried out basing on the view and method of thermal system dynamics, the parameter of the object is treated as coupling parameter. Adapting a set of ordinary differential equations, the model can reflect the transient character of condenser effectively. The model can reflect the coupling relationship between the parameters which can’t be obtained through the previous simulation model. The model has simple form and can be computed conveniently.

Abstract:
Abstract In the present paper a unified numerical approach for dynamics modeling of multibody systems with rigid and flexible bodies is suggested. The dynamic equations are second order ordinary differential equations (without constraints) with respect to a minimal set of generalized coordinates that describe the parameters of gross relative motion of the adjacent bodies and their small elastic deformations. The numerical procedure consists of the following stages: structural decomposition of elastic links into fictitious rigid points and/or bodies connected by joints in which small force dependent relative displacements are achieved; kinematic analysis; deriving explicit form dynamic equations. The algorithm is developed in case of elastic slender beams and finite elements achieving spatial motion with three translations and three rotations of nodes. The beam elements are basic design units in many mechanical devices as space station antennae and manipulators, cranes and etc. doing three dimensional motion which large elastic deflections could not be neglected or linearised. The stiffness coefficients and inertia mass parameters of the fictitious joints and links are calculated using the numerical procedures of the finite element theory. The method is called finite elements in relative coordinates. Its equivalence with the procedures of recently developed finite segment approaches is shown, while in the treatment different results are obtained. The approach is used for solution of some nonlinear static problems and for deriving the explicit configuration space dynamic equations of spatial flexible system using the principle of virtual work and Euler-Lagrange equations.
