Abstract:
Scattering of electromagnetic plane waves from a coated perfect electromagnetic conductor (PEMC) circular cylinder placed under perfect electric conducting (PEC) wide double wedge is presented. It is assumed that the distance between the two wedges is large as compared to the wavelength. Therefore, the field at an observation point can be considered to be composed of the incident field plus a response field from each of the edges of double wedge and the cylinder. PEMC cylinder is taken to be infinite along its axis and has been coated with a double positive (DPS) or double negative (DNG) material. The transmission coefficient and diffraction pattern of PEC wide double wedge in the presence of both coated and uncoated PEMC cylinder are studied. Results of special cases for PEMC cylinder, compared with the published work, are found to be in fairly good agreement. The techniques of Clemmow, and Karp and Russek have been used to investigate the transmission coefficient and diffraction pattern of the double wedge in the presence of both coated and un-coated PEMC circular cylinder.

Abstract:
In order to solve the poor control accuracy problem of the traditional synchronous control algorithm for a double-cylinder forging hydraulic press, a synchronous control algorithm for double-cylinder forging hydraulic press based on a fuzzy neural network was proposed. According to the flow equation of valve and hydraulic cylinder, the balance equation and force balance equation of forging hydraulic cylinder are established by using the theory of electro-hydraulic servo systems, and the cylinder-controlled transfer function of forging hydraulic cylinder is deduced. By properly simplifying the transfer function, the mathematical model of synchronous control of double cylinder forging hydraulic press is established. According to the implementation process of traditional fuzzy neural networks, the properties of compensation operation are introduced. The traditional fuzzy neural network is optimized, and the optimized neural network is used to realize the synchronous control of the double cylinder forging hydraulic press. The experimental results show that the amplitude curve of the algorithm is very close to the expected amplitude curve, the error amplitude is only 0.3 mm, and the average control time is about 140 s, which fully shows that the algorithm has high accuracy and a good control effect.

Abstract:
The five double layer cylinder reticulated shells (single diagonal rod cylinder reticulated shell, Foeppl cylinder reticulated shell, double diagonal rod cylinder reticulated shell, lamella cylinder reticulated shell and three way grid of cylinder reticulated shell) are developed by adopting the upper and lower translation method. Five connection forms of web member (cross truss, positive four pyramidal, upend four pyramidal, evacuated positive four pyramidal, evacuated upend four pyramidal) and the methods of the node generation and element connection are established in the cylindrical coordinate system. By using the ANSYS parametric design language APDL, the corresponding parametric design macro program is developed so that the five double-layer cylindrical shells can be parametrically modeled under the given parameters such as shell type, shell span D, rise high t, thickness h, length L and number of grids m and n, etc. Examples prove that this method is simple, efficient and pragmatic, which provides great convenience for the force analysis and the optimization scheme comparison.

Abstract:
The master thesis deals with design and comparison of condensing steam turbine for steam-gas cycle for single-cylinder and double-cylinder body with air condenser at its end, one regulated take and ability to use additive steam. Thesis is based on the calculation of thermal scheme which is followed by a preliminary and subsequently a detailed design of steam turbine. Thermodynamic efficiency for single-cylinder turbine was calculated at 93,28 % with terminal power 136,2 MW. The design procedure was repeated for a double-cylinder body. Calculated terminal power for two-cylinder turbine was 134,4 MW with thermodynamic efficiency of 92.1%. By dividing turbine into two rotors resulting low-pressure turbine has a smaller rotor diameter, a longer blade and at the same time a larger number of stages. For double-cylinder turbine, it was necessary to consider twice the number of seals and radial bearings. Due to the increase in flow diameter of low-pressure turbine, losses related to the geometry of the stage increased. Thesis is supplemented by a section drawing of steam turbine with higher efficiency.

Abstract:
This study considers the elastostatic contact problem of a semi-infinite cylinder. The cylinder is compressed against a layer lying on a rigid foundation. There is a sharp-edged circular hole in the middle of the foundation. It is assumed that all the contacting surfaces are frictionless and only compressive normal tractions can be transmitted through the interfaces. The contact along interfaces of the elastic layer and the rigid foundation forms a circular area of which outer diameter is unknown. The problem is converted into the singular integral equations of the second kind by means of Hankel and Fourier integral transform techniques. The singular integral equations are then reduced to a system of linear algebraic equations by using Gauss-Lobatto and Gauss-Jacobi integration formulas. This system is then solved numerically. In this study, firstly, the extent of the contact area between the layer and foundation are evaluated. Secondly, contact pressure between the cylinder and layer and contact pressure between the layer and foundation are calculated for various material pairs. Finally, stress intensity factor on the edge of the cylinder and in the end of the sharp-edged hole are calculated.

This study is aimed to dynamic simulation of a double acting four-cylinder Stirling engine. By combining thermodynamic model, kinematic model and dynamic model, the engine operation can be efficiently simulated. The transmission mechanism which used in this study is wobble yoke mechanism. The analysis of the force transmission from pressure that acting on four piston surfaces and then to the output shaft is considered. With the kinematic and dynamic analysis of the mechanism, all the links’ vectors of positions, velocities, accelerations, angular velocities and angular accelerations are developed, and finally the dynamic model of mechanism is carried out. In the thermodynamic model, the chamber is divided to five sub-chambers, including expansion space, heater, regenerator, cooler and compression space. Pressure, volume, temperature, mass transfer and pressure loss of the working fluid in these sub-chambers are also considered. Results of pressures from the thermodynamic model are fed into the dynamic model so as to predict the positions of the moving parts. By combining the thermodynamic and dynamic models, the torque output, indicated power, shaft power, mechanical efficiency and heat efficiency are determined eventually. Using helium as the working fluid, the steady rotation speed of the engine is found to be about 1800 rpm. When engine rotation speed is at 804 rpm, a maximum output power of 732.3 watts, and overall efficiency of 11.7% are found.

This thesis is dedicated to the investigation of the operating principle and theoretical model analysis of a double acting four-cylinder Stirling engine. A prototype engine is built for the purpose of this thesis and further analysis, and a wobble yoke mechanism is selected for mechanical design. The analysis of the double acting Stirling engine begins by dividing the engine to a single chamber, containing five sub-chambers: expansion chamber, heating chamber, regeneration chamber, cooling chamber and compression chamber. Each sub-chamber is analyzed for pressure, volume, temperature and mass variation of the working fluid. Pressure drop by friction loss is then taken into consideration. Upon completion of setting up theoretical model, it is compiled in numerical simulation under prototype engine parameters to simulate engine operating conditions. With gaseous helium as working fluid and under the condition of 6 atmospheres, 1000 rpm of engine speed, 1000 Kelvin heating temperature and 300 Kelvin cooling temperature, the resulting single chamber power is 202.94 Watts, and the thermal efficiency is 7.75%. Further investigation of four-chamber simulation with equal initial pressure conditions shows results of engine power 736.6 Watts and thermal efficiency 9.4%. In parallel, the results for a four-chamber simulation under equal mass condition are 774.7 Watts for engine power and 7.74% for thermal efficiency.

This research aims at the structure design on the dynamic characters of the air compressor. Because the size and shape of the structure materials of an air compressor will influence its whole strength, the bad structure will cause the vibration of an air compressor while it is working. This research tests the vibrations and noises of an air compressor first. Then the structure of compressor is analyzed by using the computer analyzing software. The data can provide the references of the compressor’s design of concerned manufacturers to improve its structure perfectly and shorten developing time and reducing wastage of cost.

A compact dielectric resonator antenna for ultra-wideband vehicular communication applications is proposed. Two cylindrical dielectric resonators are asymmetrically located with respect to the center of an offset rectangular coupling aperture, through which they are fed. Optimizing the design parameters results in an impedance bandwidth of 21%, covering the range from 5.9 to 7.32 GHz in the lower-band and a 53% relative bandwidth from 8.72 to 15 GHz in the upper-band. The maximum achieved gain is 12 dBi. Design details of the proposed antenna and the results of both simulations and experiment are presented and discussed.

A theoretical study is presented for the dynamic electrophoretic response of a circular cylindrical particle to a step change in the applied electric field. The electric double layer surrounding the particle may have an arbitrary thickness relative to the particle radius. The transient Stokes equation modified with the electrostatic effect which govern the fluid velocity field is linearized by assuming that the system is only slightly distorted from equilibrium. Semi-analytical results for the transient electrophoretic mobility of the particle are obtained as a function of relevant parameters. The results demonstrate that the electrophoretic mobility of a particle with a constant relative mass density at a specified dimensionless time normalized by its steady-state quantity decreases monotonically with a decrease in . For a given value of , a heavier particle lags behind a lighter one in the development of the electrophoretic mobility. For the case of large , our result reduces to the corresponding analytical solution. The growth of the electrophoretic mobility with the elapsed time for a cylindrical particle is substantially slower than for a spherical particle.

The Taiwan’s fasteners industry is of great importance in the world. Thus how to enhance the fasteners industry technology is always focused by the fields of industry, government, academics and research; where the forming technology of the bolt head belongs to the cylinder compression forming technology. The controls of dimensions precision, compression force, and the related plastic working method, all affect the development of fasteners technology. The bulging deformation is induced by the interface friction under the cylinder compression and the energy loss is made. The phenomenon is more obvious due to the increase of reduction ratio. The energy loss indicates the cost raise, however the bulging deformation makes the geometry accuracy reduced and the flow stress evaluation wrong. Therefore, if the compression force and bulging deformation can be predicted before the forming process, it is of significant benefit for those high adding value products with highly required accuracy and quality. Even for metal manufacturing industries, the error and distortion induced by bulging effect in the processing of plastic deformation are inevitable; especially the bulging deformation of cylinder compression usually leads to the geometrical error of metal forming and the prediction distortion of flow stress. For solving these problems, this study considering constant shear friction proposes a hybrid approach which combining the upper bound method (UBM) with the elliptical curve-fitting method to predict the compression force and bulging deformation. This study shows that the compression forces predicted by the hybrid method are in good agreement with the experimental results and those obtained from Finite Element Method (FEM) simulations and Slab Method (SM). In addition, the predicted bulge profiles of the compressed cylinders are in good agreement with the experimental profiles and those obtained from FEM. It can be seen, the objectives of predicting compression force and bulging deformation profile in the cylinder compressing can be reached by properly utilizing the volume conservation constraint of metal plastic deformation and a geometrical method of elliptical curve-fitting technique. In other words, the hybrid elliptical curve-fitting method can fast predict the bulging deformation of cylinder compression, not to use the variational iteration method to solve it. Regardless of whether single-layer or double-layer cylinder compression; besides considering whether the lower die is rotating or not, the hybrid method can be used to analyse it. The objective of this study aims at the rotating compression of single-layer and bonded double-layer clad cylinder to establish three analytical models including the hybrid method combining the Upper Bound Method with the elliptical curve-fitting, the Slab Method, and the Finite Element Simulation. As for the prediction of bulging deformation, apart from the FEM simulation, the other hybrid method can combine the UBM with an elliptical curve-fitting method for predicting compression force and bulging deformation. Meanwhile, the compression force and bulging deformation between analyses and experiment are compared to verify the acceptance of this study. These models established can be offered to metal forming industries.

The double diffusive mixed convection phenomenon in the vented cavity affected by the inlet fluid conditions is numerically investigated in this study to analyze the fluid flow, temperature and concentration distribution as well as the performance of heat and mass transfer.The parameters studied and their ranges are Lewis number 1≦Le≦10, buoyancy ratio -2≦Br≦2, Richardson number 0.01≦Ri≦10, Reynolds number 10≦Re≦200, respectively.The results show that the flow structure is affected by the strength both of forced convection and natural convection.The average heat transfer and the average mass transfer rate are enhanced as the stronger mixed convection effect, especially for the higher Reynolds number and Richardson number combination.The average heat transfer rate decrease but the average mass transfer rate increase as Lewis number increase.The effects of the positive values of buoyancy ratio result in the enhancement both of the average heat transfer rate and the average mass transfer rate, but the results of the negative values of buoyancy ratio show small differences due to the forced convection suppressed by natural convection.

Abstract:
This chapter defines cohomology of Aubry-Mather type and explains why it implies one of the diffusion mechanisms, after a generic perturbation. The definition of Aubry-Mather type includes a much simpler case, that is when the Aubry set is a hyperbolic periodic orbit, still contained in a normally hyperbolic invariant cylinder. This definition says that each of the two local components of the Aubry set is of Aubry-Mather type. There is another type of bifurcation in which one component of the Aubry set is of Aubry-Mather type with an invariant cylinder and another is a hyperbolic periodic orbit. This can be called the asymmetric bifurcation. This case appears at double resonance, when the shortest loop is simple non-critical.

Abstract:
This chapter proves the geometric picture of double resonance described in Chapter 4. There are two cases. In the simple critical homology case, the chapter shows the homoclinic orbit can be extended to periodic orbits both in positive and negative energy. The union of these periodic orbits forms a normally hyperbolic invariant manifold (which is homotopic to a cylinder with a puncture). In the non-simple homology case, the chapter demonstrates that for positive energy, there exist periodic orbits. The strategy is to prove the existence of these periodic orbits as hyperbolic fixed points of composition of local and global maps. A main technical tool to prove the existence and uniqueness of these fixed points is the Conley-McGehee isolation block.

Abstract:
This chapter proves Aubry-Mather type for the double resonance regime. It begins by considering the “non-critical energy case” and showing that the cohomologies as chosen are of Aubry-Mather type. The proof consists of two cases. In the first case, the chapter uses the almost verticality of the cylinder, and the idea is similar to the proof of Theorem 9.3. It applies the a priori Lipschitz estimates for the Aubry sets. In the second case, the chapter uses the strong Lipschitz estimate for the energy, and the idea is similar to the proof of Theorem 11.1. It then looks at the construction of the local coordinates. This is done separately near the hyperbolic fixed point (local) and away from it (global).

Abstract:
Double-cylinder parallel manipulators are closed-loop two-degree-of-freedom linkages. They are preferred to use because of their simplicity plus the common advantages of parallel manipulators such as high stiffness, load-bearing, operation speed and precision positioning. Like other parallel manipulators, the output motion of double-cylinder parallel manipulators is not as flexible as two-degree-of-freedom serial manipulators. The motion performance analysis plays a critical role for this type of parallel manipulator to be applied successfully. In this paper, the linkage feasibility conditions are established based on the transmission angle. When feasibility conditions are satisfied, there is no dead position during operation. The workspace is generated by using curve-enveloping theory. The singularity characteristics are analyzed within the workspace. The motion performance index contours within the workspace are produced using the condition number of the manipulator Jacobian matrix. The results of this paper provide guidelines to apply this type of parallel manipulator.

Abstract:
Based on an eigenfunction expansion of velocity potential and a linear model between the pressure difference between two sides of a perforated wall and the fluid velocity inside it, a semi-analytic linear solution has been acquired for wave interaction with a combined cylinder with an solid interior column surrounded by a coaxial exterior column with perforated wall at a section in azimuthal direction. Numerical experiments have been carried out to examine the influences on the wave force and wave run-up on the combined cylinders with perforated wall by the porous coefficient, the size of the perforated section, and the ratio between the radii of the interior and the exterior columns. This paper also presents the comparison between the numerical experiments results and the physical experiments results. It is acceptable of the comparison of these two results. The combined cylinder may reduce both the wave run-up and the wave loads on it through combination of certain parameters.
