Abstract In order to promote the development of sports training robots and improve the training of lower limbs in Sanda, a new mechanical structure of Sanda training robots is designed. The thesis combines the mathematical method of fractional differential equations to design a new type of omnidirectional moving platform mechanism, which realises the movement in any direction in the plane and can turn at any radius during the movement. From the perspective of kinematics, the mathematical relationship between wheel speed and robot trajectory is analysed, and a virtual prototype technology combined with Pro/E and Adams joint modelling and simulation method is used to establish an accurate and reliable virtual prototype model. The experimental simulation results show that the designed virtual prototype model is consistent with the mathematical model, which verifies the practical feasibility of the mechanical structure of the lower limb power generation robot for Sanda movement, and provides a reliable basis for the establishment of the physical prototype.

Railway ballast tamping operations is an important work in the line maintenance and repair operations, the selection of tamping parameter is usually dependent on field trials and practical experience, for the mechanical properties of railway ballast is difficult to measure and describe. This paper creates discrete element analysis model of railway ballast using the discrete element method, the numerical simulations are carried out to study the mechanical properties of railway ballast during tamping process. We focus on the influence of amplitude during tamping process; an optimal amplitude of the simulation analysis is obtained and compared with the recommended amplitude of Plasser & Theurer Company, it is found that the two amplitudes accord. This result verifies the correct validity of the discrete element analysis model of railway ballast during tamping process.

The joint simulation of Virtual Prototype Technology and Finite Element Method was utilized to perform the analysis of both strength and fatigue life of the input axis in a six-speed vehicle transmission with three axes. Firstly, the software Pro/E was used to establish a 3-D model of the input axis and its gear engagement, and the model was then imported into a software ADMAS of the virtual prototype technology to perform a dynamic simulation analysis. Secondly, the gear contact forces obtained by above-mentioned analysis were used as the loading condition of finite element analysis of the input axis to check its strength. Finally, the fatigue of meshing teeth on the input axis was analyzed to determine the fatigue life of the input axis. The results show that the static strength of input axis can meet the requirement of safe use under the working condition of input torque T=1.5kN·m, and the minimum fatigue life on the place where the stress is maximum at flexural root of a tooth is about 2 million times.
