摘　　要：结合汽车用减振器的工作特点,按照轿车悬架的技术要求,设计了基于混合工作模式的单出杆单筒磁流变减振器。根据流体力学理论,建立混合工作模式下磁流变减振器计算模型,并对磁流变减振器的阻尼力、动态响应时间及其影响因素进行了理论分析,进行了实物样机研制。对研制的磁流变减振器进行台架测试,分析了阻尼特性和动态响应时间,试验结果表明:设计的单出杆单筒磁流变减振器具有较大的阻尼力与和较宽的阻尼力调节范围,并且动态响应时间较短,能满足汽车半主动悬架对减振器的使用要求。According to the working characteristics of automotive shock absorber and the technical requirements of car suspension,a single rod and single cylinder magnetorheological shock absorber is designed.Based on the theory of hydrodynamics,the calculation model of MR damper under mixed working mode is established,the damping force,dynamic response time and influencing factors of MR damper are theoretically analyzed,and the physical prototype is developed.The damping characteristics and dynamic response time of the MR damper are analyzed.The test results show that the designed single rod and single cylinder MR damper has large damping force and wide damping force adjustment range,and short dynamic response time,which can meet the application requirements of automotive semi-active suspension.
