The Study of the Installation Angle of Anti-hunting Dampers on Bench Test

Abstract

In this paper, the effect of the installation angle of anti-hunting damper on the hunting stability and the ride index of high-speed trains was verified through tests on roller rig. Firstly, the roller rig and related test methods were introduced, and then the changes in the dynamic performance of the vehicle were analyzed based on the test results. The results show that the vehicle has a higher nonlinear critical speed when the anti-hunting damper is installed horizontally. The installation angle of the anti-hunting damper has a great influence on the vertical ride index of the vehicle. With the increase of test speed, the difference of vertical ride indexes of vehicles under the two installation angles increases, and the vertical ride index of the vehicle is poor when installed at an angle.
