With the increase of the train speed, the vertical and transverse interaction between wheel and rail would result in excessive vibration of vehicle systems. Hydraulic damper is effective energy dissipation device. So, it is widely used in the rolling stock. Hydraulic damper have been becoming an important part in the rolling stock for improving the comfort and assuring the safety of railway transportation.
The operating principle of hydraulic damper is to absorb vibrational energy using th...
