摘要
首先利用ADAMS软件建立带有电动助力转向系统(EPS)的整车多体动力学模型;然后在Matlab/Simulink环境中设计了PID控制的EPS系统,定义了与ADAMS/CAR环境下车辆模型的数据交换接口;最后,将设计的控制系统在ADAMS/CAR和Matlab/Simulink环境下通过输入输出接口进行联合仿真。几种行驶工况下的EPS及整车的动态特性计算结果,表明联合仿真方法是正确有效的,并为其在车辆工程中的实际应用提供了参考。
A simulation model with multi-body dynamics and electronic power steering （EPS） was presented based on the co-simulation technology. First, by using automatic dynamic analysis of mechanical systems （ADAMS） software, a multi-body dynamic model of a full vehicle was established, then a PID controller was designed for the EPS under Matlab/Simulink environment; in addition, a data exchange interface with ADAMS/CAR was also defined. At last, a proposed control system including a multi-body vehicle model and a PID controller was implemented by using I/O interface under Matlab/Simulink and ADAMS environment, and the co-simulations have been carried out. The vehicle dynamic response under various operating condition was given. The results showed that co-simulation is effective and it could be applied in the development of vehicle engineering.
