摘要
传动系统对电动汽车的性能影响重大,直接关系到电动汽车的动力性和经济性。针对某两挡变速器电动汽车传动系统的结构特点,将传动系统视为刚体系统,建立了3自由度动力学仿真模型,并使用Matlab进行仿真,得到了传动系统的响应特性。其结果为传动部件的匹配和机电控制方法的制定提供了依据。
Transmission system which directly relates to the dynamic and economic performance of vehicle has a great impact on the performance of electric vehicle. Aiming at the structural characteristics of the transmission system of a two - speed electric vehicle, by regarding transmission system as a rigid body system, the 3 degrees of freedom dynamics simulation model is built. And by using Matlab as a simulation tool, the response characteristic of transmis- sion system is gained. A basis for the matching of transmission components and the formulation of electromechanical control methods is provided by the simulation results.
