摘　　要：在建立整车磁流变减振器（MRD）半主动悬架模型基础上,利用八板块方法设计了整车的变论域控制策略。基于重构的标准B级和C级路面激励信号,分别在10、20和30 m/s 3个车速下进行了整车在直线和转向行驶工况下的仿真研究。在完成试验车辆改装基础上,进行了大量台架和道路工况下的试验。仿真和试验结果显示,所设计的半主动悬架和控制策略可以有效地提高车辆行驶的平顺性,磁流变半主动悬架与被动悬架相比振动强度可降低9%~22%,结果表明所建立的模型和控制策略是可行的。The variable universe control strategy was adopted from the octa-plate control method for whole vehicle MRD semi-active suspension model.Simulations of vehicle travelling both straight and turning with the speed of 10 m/s,20 m/s and 30 m/s were done in reconstruction standards B and C level road excitation signal.Large numbers of bench tests and road test have been done upon the completion of the modification of the vehicle.Simulation results showed that the designed semi-active suspension and control strategy had effectively improved the smoothness of the ride and there was 9% to 22% reduction in vibration intensity of the magneto rheological semi-active suspension and the passive suspension.The results showed that the model and the control strategy were feasible.
