滚动试验台预紧力设置探讨

Discussion on preload setting of a rolling test rig

针对某机车滚动试验台的牵引定位装置的预紧力设置问题,通过理论分析和现场试验得出滚动台两端拉压力传感器示数变化与机车轮周牵引力之间的关系,从而总结出试验前所需的预紧力与机车轮周牵引力之间的关系。

Aiming at the preload setting of traction positioning device on a locomotive rolling test rig,this paper finds out the relationship between traction force and data changes of pull-pressure sensor by theoretical and test analysis, and summarizes the relationship between the preload and traction force.
