前言铁路机车的动力性能是由许多因素决定的。而众所周知的蛇行现象则是机车悬挂系统的设计师们所特别关心的。当铁路机车横向振动发展到不稳定的时候,蛇行就发生了,其表现的特征是机车各部件不断增大的运动。这时,轮对装置沿两根钢轨横向振动,机车与转向架构架绕垂直中心线做回转运动,同时又横向窜动,而车体则相应地作回转运动和侧滚运动。但应着重指出的是,这种现象与线路情况
Preface The power performance of railway locomotives is determined by many factors. The well-known hunting phenomenon is the locomotive suspension system designers are particularly concerned about. When the lateral vibration of a railway locomotive developed to instability, the serpentine occurred, and its performance was characterized by the ever-increasing movement of the locomotive components. At this time, the wheelset vibrates transversely along the two rails, and the locomotive and the bogie frame rotate back and forth about the vertical centerline, and at the same time, they move transversely, while the car body rotates and scrolls accordingly. But it should be emphasized that this phenomenon and the line situation
