摘　　要：应用电磁感应的基本原理,设计了一种响应快、出力大和动行程长的车辆主动悬架用作动器。建立了该作动器的集总元件的动力学模型并进行仿真;同时对制作的样机进行了斜坡电压输入和方波电压输入的电磁力测试,测试与仿真结果很好吻合,验证了模型的准确性。最后,结合最优控制理论和矢量控制方法,对包含作动器动力学模型的车辆主动悬架系统进行了正弦路面激励下的仿真分析,结果表明,与被动悬架系统相比,主动悬架系统能明显提高车辆的平顺性。By applying the basic principle of electromagnetic induction,a vehicle active suspension actuator with the features of fast response,large force and long stroke is designed.The dynamics model for the lumped element of the actuator is built and a simulation is performed.Meanwhile a test is conducted on the prototype of actuator with both ramp and square wave voltage inputs.The good agreement between simulation and test results verifies the correctness of the model.Finally combined with optimal control theory and vector control scheme,a simulation is carried out on the vehicle active suspension system with actuator dynamics model under sinusoidal road excitation.The results show that compared with passive suspension system,active suspension system can markedly improve the ride comfort of vehicle.
