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.

Irregular Structure

More and more irregular structure appears in people's lives, while the theoretical research and disaster experience show that the irregular structure in the earthquake will produce translation and torsion coupled spatial vibration, and sometimes it will cause very serious consequences. Being based on the practical engineering -the Castle Hotel of Dalian, this text makes use of finite element analysis software--- ANSYS. By analyzing the dynamic characteristics and seismic response, we get the self-vibration characteristics of the structure and the time history curve of top level displacement and acceleration of the structure under the effect of earthquake forces. The calculation results indicate that it is effective and reasonable to set up three-dimensional finite element model used for the analyzing of seismic response by ANSYS.

According to the insufficient force analysis of the cable in the process of winch retraction, especially the insufficient research on the flexible cable retraction process such as the UHMWPE cable, the dynamic simulation analysis of the retraction process of the parallel grooved multi-layer drum and UHMWPE cable cable is carried out by using the virtual prototype software ADAMS. The simulation model of the cable is created by using the macro command program, and the virtual prototype model of the cable drum is completed, and the force changes of the cable under different rotating speeds are simulated.The simulation results show that the contact force between the cable and the double winding drum can be quickly stable under the specific load, and with the increase of the rotating speed, the maximum value of the tension change of the cable increases, but it is finally stable at a fixed value. The results can provide some reference for structural strength calculation of cable storage drum, selection of high molecular polyethylene cable and dynamic analysis of cable arranger under load.

According to the principle of double-half-revolution mechanism, a new kind of quadruped-imitating walking mechanism was designed. In order to simplify the structure of the walking mechanism, each links of the mechanism is driven directly by steering gear.Considering non-interference condition of each links and undulation requirement during movement, the constraint functions were established. In order to ensure the movement feasibility and reduce the undulation of the walking mechanism, optimization design for the size parameters of each links were completed by using Matlab optimization tool. The virtual prototype model of quadruped-imitating walking mechanism was set up in SolidWorks software, and the rationality of the optimization design was verified through the simulation analysis.
