介绍了一种检测减振器故障的方法,该方法依据由加速度计获得的转向架构架或车体的浮沉运动和点头运动间的相位差进行检测。试验台试验和线路运用试验表明,本文所提出的方法既能判断出减振器是否发生故障,又能确定故障减振器所在的位置。
A method for detecting the failure of a shock absorber is presented. The method detects the phase difference between the swaying motion and the nodding motion of the bogie frame or body obtained by the accelerometer. Test bench test and circuit test show that the method proposed in this paper can not only determine whether there is a failure of the shock absorber, but also determine the location of the fault absorber.
