摘　　要：提出一种基于加速度阻尼原理的改进型半主动控制,可以克服天棚阻尼半主动控制在高频范围内抑制振动效果差的缺点。突破了以往研究半主动控制只针对单车车辆的限制,利用ADAMS(Automatic Dynamic Analysis of Me-chanical Systems)建立了2动2拖104个自由度动车组模型,并结合Matlab/Simulink对提出的半主动控制方法进行设计和联合仿真。根据联合仿真的结果,从时域和频域两个角度对比两种半主动控制方法对车辆运行平稳性和安全性的影响,并分析控制中时滞对系统性能的影响。结果发现,改进型半主动控制在提高车辆运行平稳性和抗时滞方面效果更佳。The bad effect on vibration reduction usually appears when adopting a traditional skyhook semi-active control in high-frequency domain.In order to overcome the disadvantage,an improved semi-active control strategy based on acceleration damping was proposed.A high speed EMUs(Electric Multiple Units)model containing two motor cars and two traction cars with 104 DOFs was built by using conventional software ADAMS(Automatic Dynamic Analysis of Mechanical Systems),which breaks through the traditional methods' limitation of single car based model.The proposed semi-active control methods were designed and co-simulated by combined use of ADAMS and Simulink.According to the co-simulation results,the effects of two semi-active control methods on riding quality and safety were compared in both time domain and frequency domain,and the influences of time-delay on system performances were analyzed.The results show that the performances of improved semi-active control are better in riding quality and vibration reduction.
