Motion State and Transient Analysis of the Hybrid Power Coupling Mechanism Based on Matlab and Solidworks

The hybrid vehicle is an important development of the automobile industry because of its capabilities in reducing pollution and saving energy. The key component of its power system is the power coupling mechanism which determines the power efficiency. Therefore, the planetary gear power coupling mechanism which is applied in heavy hybrid vehicles is studied. By using Matlab, an entire vehicle simulation model is established to obtain the output rotating speed and torques under different working conditions. And with the application of Solidworks, a simulation model of the coupling mechanism is set up to obtain its dangerous working period. Then, the simulation data are used to carry out the transient analysis of the coupling mechanism working during the dangerous period. The research results indicate that this method is simple and reliable and can provide technical support for strength-optimized design of the mechanism.
