Abstract:
ABSTRACTMuscle function within an organism depends on the feedback between molecular and meter-scale processes. Although the motions of muscle's contractile machinery are well described in isolated preparations, only a handful of experiments have documented the kinematics of the lattice occurring when multi-scale interactions are fully intact. We used time-resolved X-ray diffraction to record the kinematics of the myofilament lattice within a normal operating context: the tethered flight of Manduca sexta. As the primary flight muscles of M.sexta are synchronous, we used these results to reveal the timing of in vivo cross-bridge recruitment, which occurred 24 ms (s.d. 26) following activation. In addition, the thick filaments stretched an average of 0.75% (s.d. 0.32) and thin filaments stretched 1.11% (s.d. 0.65). In contrast to other in vivo preparations, lattice spacing changed an average of 2.72% (s.d. 1.47). Lattice dilation of this magnitude significantly affects shortening velocity and force generation, and filament stretching tunes force generation. While the kinematics were consistent within individual trials, there was extensive variation between trials. Using a mechanism-free machine learning model we searched for patterns within and across trials. Although lattice kinematics were predictable within trials, the model could not create predictions across trials. This indicates that the variability we see across trials may be explained by latent variables occurring in this naturally functioning system. The diverse kinematic combinations we documented mirror muscle's adaptability and may facilitate its robust function in unpredictable conditions.

Abstract:
The working environment of construction machinery is harsh, and some operations are highly repetitive. The realization of intelligent construction machinery helps to improve economic efficiency and promote industrial development. Construction machinery is different from ordinary passenger vehicles. Aiming at the fact that the existing environmental perception data set cannot be directly applied to construction machinery, this paper establishes the corresponding data set in combination with the specific working conditions of construction machinery and carries out training based on the PointPillars network to realize the environmental perception function applicable to the working conditions of construction machinery. Most construction machinery runs on unstructured roads, and the existing passenger vehicle path planning algorithm is not applicable to construction machinery. Based on this, this paper uses a hybrid A* algorithm to achieve path planning that meets the kinematics of construction machinery and realizes real-time obstacle detection and avoidance. At the same time, this paper combines environmental perception with a path planning algorithm to provide a method of autonomous path finding and obstacle avoidance for construction machinery. Based on the improved pure pursuit algorithm, the high-precision motion control and established trajectory tracking of construction machinery are realized, which lays a certain foundation for the follow-up research and development of related intelligent technologies of construction machinery.

Abstract:
With the rapid development of information technology, industry and service industries have achieved rapid development in recent years. Then, looking at the development of agriculture, the popularity of informatization lags far behind industry and service industries, directly hindering the digital development of agriculture. Starting from the current agricultural machinery driving operation scene, this paper carried out a simplified research on the traditional agricultural machinery driving operation method through the agricultural machinery kinematics model, and based on the related theory of deep reinforcement learning to study the agricultural machinery path tracking in the agricultural operation scene, it carried out the controller design, built the agricultural machinery autonomous path tracking framework operating mechanism under deep reinforcement learning, and further researched through experimental design and found that the agricultural machinery autonomous path tracking control can achieve better automatic control after empirical learning. I-DQN algorithm enables agricultural robots to adapt to the environment faster when performing path tracking, which improves the performance of path tracking. It has important guiding significance for further promoting the automatic navigation and control of agricultural machinery to realize the efficient operation of agricultural mechanization.

Abstract:
Currently, there is much interest in the field of robotics in researching methods of obtaining inverse kinematics solutions for arbitrary manipulators. Simple closed-form inverse kinematics equations can be obtained for a few joint configurations using geometric methods. However, there exist many manipulators which were not originally designed for kinematic control which do not have simple closed-form inverse kinematics equations. An efficient and stable iterative method is investigated in this thesis which solves the general inverse kinematics problem without detailed analysis of the manipulator's structure. The proposed iterative inverse kinematics algorithm combines a calibration procedure to estimate the manipulator's Denavit-Hartenberg parameters with an iterative method using the Jacobian and damped joint corrections. The kinematics control algorithm parameters are selected with a computer graphics simulation of the manipulator. The proposed inverse kinematics algorithm is tested with a simulation of an industrial manipulator arm which does not have a closed-form solution, RSI Robotic Systems International's Kodiak arm, and exhibits stability in all regions of operation and fast convergence over most regions of operation.

Abstract:
The research described was aimed at developing passive vision techniques to perform kinematic calibration for a multi-link manipulator, in near real time. Working with a single image of the arm of a Caterpillar excavator, edges are extracted first, then the constrained nature of the problem allows filtering of edge elements to select only those potentially arising from the arm. A model based matching process is performed on this refined data to determine the desired joint angles quickly and efficiently. Methods of exploiting the parallel nature of these techniques are also described.

Abstract:
Computer programs have been developed for the kinematic and dynamic analyses of cascades of planar four-bar mechanisms. Since the analytic approach has high efficiency and accuracy in computation, a chain of four-bar linkages is developed horizontally and vertically by using the relative coordinates and the absolute coordinates, from which the explicit equations and the simultaneous equations are respectively derived in the kinematic analysis. In this analysis, the actions of transmission of linkages, from left to right, from right to left and from lower to upper, are performed by the image method and transformation procedures. Based on the kinematic analysis, the dynamic analysis is also developed by using both sets of coordinate systems. The generalized equation of motion, the general form of Lagrange's equations, Lagrange multipliers and the theorem of power balance are used to construct various formulations of the governing equations of motion for some particular problems. The problem of a linkage with a moving frame (the ground link) is the most interesting focus in this analysis.

The purpose of this thesis is to provide a complete package for the synthesis and design of the RSSR spatial function generating mechanism.

In addition to the introductory material this thesis is divided into three sections. The section on background kinematic theory includes synthesis, analysis, link rotatability, transmission quality, and branching analysis. The second division details the computer application of the kinematic theory. The program RSSRSD has been developed to incorporate the RSSR synthesis and design theory. An example is included to demonstrate the computer-implemented theory.

The third part of this thesis includes miscellaneous mechanism considerations and recommendations for further research.

The theoretical work in this project is a combination of original derivations and applications of the theory in the mechanism literature.

Abstract:
Dynamics of Machinery is a traditional engineering course; in fact kinematics was one of the earliest fields of study in engineering. The course relies on a strong combination of learning new theory and acquiring the skills to apply this theory through regular and repeated practice. This practice is commonly incorporated through homework sets, provided through a combination of book or instructor-given assignments. This homework includes testing conceptual understanding of key concepts, creating kinematic schematics, vector model construction, constructing equations, and performing mathematical analyses. The use of online, electronic tools for automating homework has been widely incorporated in K-12 education and in some college-level curriculum, but not, to the authors’ knowledge, significantly in a kinematics and dynamics of machinery class. This paper will present a framework for creating these problems, provide an overview of an entire set of problems associated with the common kinematics curriculum, and present an evaluation of this digitized coursework throughout four semesters of implementation.

Results for various cases are shown and are ready to be used in a study of the dynamics of the generalized slider-crank.

Abstract:
Dynamics of Machinery is a traditional engineering course based on long-standing kinematic theory and proven practices. Given the established nature of the class, Dynamic of Machinery could be considered for a flipped classroom model in which students watch a prerecorded lecture prior to class, and then spend class time practicing the theory through examples. One of the limitations to the flipped model is the concern that students have not fully grasped the material from the recorded lecture. This paper suggests the use of a concept quiz associated with each pre-recorded lecture as a required component to meet prior to attending the class. The concept quizzes are associated with each unit lecture and collectively should form a concept inventory for the class that defines the fundamental range of knowledge for successful students. This paper will present the format the concept quizzes and how they are used in the flipped class environment for a traditional, junior level kinematics of machinery course. The paper will present the concepts according to topics and divided among 39 lectures associated with each class.

Full text
Abstract:
Abstract Large guided chains are often used in manufacturing machinery to move materials and tooling. In such applications, the accuracy of the motion of the chain has a significant impact on the quality and yield of the process. The motion of the chain will be dependent on the geometry of the machine, the dynamic parameters of the machine, and the exact tolerances of the machine components. The research presented in this paper will first address the kinematics of a chain system. The analysis will include both chordal effects and link length variations, which affect the engagement between the chain and the drive sprocket. Second, the kinematic analysis will be used to develop a dynamic analysis based upon Lagrange’s equations for a chain system with variable link lengths. Results are presented which demonstrate the influence of chain mass and drive stiffness on the dynamic behavior of the system operating at both low and high speeds with oversized links.

Abstract:
The study deals with the compensation of gravity loads in closed-loop mechanisms as a possible strategy for enhancing their working performance. This work focuses on the Orthoglide 5-axis, a prototypal parallel robot for milling operation, characterized by linear-delta architecture with two further serial DOFs. Starting from a general theory formerly proposed by the authors, gravity compensation of the mechanism is analytically carried out. The statically balanced Orthoglide 5-axis can be obtained by installing on one leg a proper set of extension springs and a simple additional linkage. A feasible design solution for developing the device in practice is presented. The proposed balancing device can be implemented with minor modifications of the original robot design, thus appearing a profitable solution to be possibly extended to other machinery with similar architecture.

The acoustic loads result from the flows nonuniformity, flow path obstacles or the machine kinematics. The acoustic waves frequently interact with the structural modes inside the turbo-machine. Such interactions may contribute significantly to structural failures and therefore are of primary interest to a machine designer. High ‘efficiency’ couplings usually lead to structural failures while low ‘efficiency’ couplings are not important. Thus, assessment of the coupling ‘efficiency’ is crucial in the calculation of failure probabilities. This knowledge could also be used during the root cause failure analysis or in the machine re-design process. The most ‘efficient’ coupling takes place when the so-called joint acceptance function, representing spatial coupling ‘efficiency’ and the transfer function, representing time coupling ‘efficiency’, describe full coincidence of the acoustic and structural modes. Partial couplings are usually unimportant due to their low ‘efficiency’. This paper attempts to explain partial and complete coupling concepts based on example of a failed compressor impeller. Some practical design remedies to avoid impeller failures are given while predicting the complete coupling.

Abstract:
The field of parallel kinematics was viewed as being potentially transformational in manufacturing, having multiple potential advantages over conventional serial machine tools and robots. However, the technology never quite achieved market penetration or broad success envisaged. Yet, many of the inherent advantages still exist in terms of stiffness, force capability, and flexibility when compared to more conventional machine structures. Deployment of Parallel Kinematic Machines in Manufacturing examines why parallel kinematic machines have not lived up to original excitement and market interest and what needs to be done to rekindle that interest. A number of key questions and issues need to be explored to advance the technology further.

Abstract:
This report examines a novel methodology for approximate prediction of the on-bottom kinematics in shallow waters and shore approach regions. The method involves simulation of generic shallow water scenarios in the Danish Hydraulic Institute MIKE software by assuming a range of seabed slopes and sea states. The simulation results are compiled in a database and a machine learning model is fitted for fast extraction of the desired surface or bottom data. The outcome of this scope of work is very useful when a pipeline stability assessment is required in shallow water areas, where no site-specific met-ocean engineering data is available. In the future, this database could be expanded to cover more ranges of input data and be implemented in the PRCI On-Bottom Stability software.
