摘要
对安装磁流变液阻尼器的悬挂式座椅的挡板冲击和减震性能进行评价,并与安装传统阻尼器的同样悬挂式座椅的性能进行对比。在振动实验台上通过分别给座椅阻尼器施加临近主频的瞬态激励、连续随机激励EM1以及放大150%的EM1激励进行性能测试。
The end-stop impact and vibration attenuation performance of a suspension seat equipped with MR(magneto-rheological) fluid damper were evaluated and compared to those of the same with a conventional damper.The performance test was conducted on a vibration exciter by imposing a transient excitation with almost dominant frenquency,continuous random excitations of class EM1 and a 150% EM1 excitation on the seat.
