英文摘要：

In order to enhance ride performance of automobile,an electromechanical actuator suspension is proposed and hardware-in-the-loop simulation testing platform of electromechanical actuator suspension is designed.Mathematics and simulation models of active suspension based on electromechanical actuator are built.Controller of electromechanical actuator suspension is designed by taking embedded system singlechip computer as the CPU.On these bases,hardware-in-the-loop simulation testing platform of electromechanical actuator suspension is built by taking dSPACE as the working carrier of models.Simulations are carried out by using the testing platform.The results indicate that the testing platform has good function of carrying out HILS and can verify and estimate the performance of electromechanical actuator suspension and controlling algorithm of active suspension.
