中文摘要：
针对目前应用于汽车悬架系统的磁流变减振器工作时需要外部电源和控制设备的问题,设计了一种新型磁流变减振器,该减振器在无需外部电源和控制设备的条件下实现了对振动的自适应控制。研究了该减振器的结构特征和电能收集理论模型,并进行了模拟仿真。利用该减振器构建了无需外部电源和控制设备的汽车自适应磁流变悬架半主动控制系统,在1/4悬架实验台上进行了实验研究,实验结果表明,该控制系统是可行的,明显提高了汽车行驶的平顺性。
英文摘要：
According to the problem of power supply and control for current automobile MR suspensions,a new MR damper was designed to control the vibration of vehicle suspensions,which can isolate vibration intellectually under no-power and no-control device circumstances.A dynamic equation for the new MR damper was derived and a simulation study based on Matlab and PSPICE was conducted to check the ability of harvesting energy.Based on this new MR damper,an automobile self-adaptive MR suspensions semi-active vibration control system was constructed and tested on 1/4 vehicle suspension test rig.The experimental results show that the automobile self-adaptive MR suspensions vibration control system based on the new MR damper is feasible and can improve ride comfort of vehicle effectively.
