在轴箱和构架之间采用液压减振器不一定总是成功的。对于摩擦式减振器,如果它的阻尼与位移速度关系不大,并且在两次较大的检修期间能保持足够的稳定时,就不应该排斥对它的采用。在外加干扰频率等于系统的自振频率时,系统就会产生共振。而在较大的速度范围内运行时所遇到的干扰频率不是一个定值,在高速运行时能引起特别厉害的位移速度和加速度。 The use of hydraulic shock absorbers between axleboxes and frames is not always successful. For frictional shock absorbers, its damping should not be excluded if its damping has little to do with the displacement speed and remains sufficiently stable during two major overhauls. When the external interference frequency is equal to the natural frequency of the system, the system will resonate. However, the interference frequency encountered when operating in a large speed range is not a fixed value and can cause particularly severe displacement speed and acceleration at high speed.
