Dynamic Feature Simulation Analysis of AutoUniversal Transmission Device

The three-dimensional model of the universal transmission device was built up by using Pro/E software and the dynamic characteristic simulation analysis is respectively carried out on the auto transmission device based on ADAMS software and ANSYS software.Getting angle acceleration and angle velocity curves by theoretical calculations and kinematics simulation of the established model;and then, natural frequency and vibration mode can be obtained by modal analysis of intermediate shaft.Results indicate that simulation curves are in consistent with theoretical analysis, modal results are agree with the experimental data and it is effectively that the model of the universal transmission device is reasonable and reliability.At the same time, the simulation results can simplify the design process of the universal transmission device, which lay a good foundation for structure optimization universal transmission device.
