MRD在铁路车辆减振上的应用

Application of MRD in railway vehicle vibration reduction

MRD是一种以MRF为介质能够输出连续可调阻尼力的半主动控制减振器,在铁路车辆振动控制上有广阔的应用前景。文章阐述了铁路车辆振动的原因及现有铁路车辆减振器的研究情况,介绍了MRD的工作原理;针对铁路车辆运行实际,讨论了MRD在铁路车辆实用化进程中还有待解决的问题。

The MRD is a semi-active control demper that can output continuous adjustable damping force by usingMRF as medium, and has expansive application prospect in vibration control of railway vehicle. This paper describesthe causes of railway vehicle vibration and the research condition on railway vehicle demper, and introduces theworking principles of MRD. Aiming at the actual running of railway vehicle, this paper discusses the issues that MRDstill has to solve in the practical application process of railway vehicle.
