基于键合图的行星变速器换挡过程动力学仿真

Dynamic simulation of the gear-shifting process of the planetary gear system based on the bond graph

基于键合图理论建立行星变速器换挡过程的动态仿真模型,推导出系统的状态方程,用M atlab/S imu link软件对其进行动态仿真,仿真结果很好地揭示了换挡品质的优、劣与换挡时间的关系,对换挡品质的控制提供理论基础。

Based on the bond graph, a dynamic simulation model of gear-shifting process of the planetary gear system was developed, depend on which the state equation of the system was deduced. The dynamic simulation was carried out by the Matlab/Simulink software which disclose the relationship between gear-shifting quality and shifting time and provide a theory method for controlling gear-shifting quality.
