一般研究和计算机车运动问题时,都假定车轮和钢轨是新的,具有标准的截面形状。但是,这种新截面形状,是不能保持很久的。新换上的钢轨,新造的车轮轮箍,一经使用,就出现了或多或少的磨损。在大多数时间内,轮轨是在磨损状态下工作的。对于磨损后的机车运动力学现象,研究得并不多。并不是磨损因素可以忽略。而是注意这个问题的,还比较少。计算机车的曲线运动,研究机车运动稳定性,计算振动,由于磨损轮轨的接触过程大小不相
In general research and computational vehicle motion problems, it is assumed that the wheels and rails are new and have a standard cross-sectional shape. However, this new cross-sectional shape can not last long. New rails, new wheel hubs, when used, appear more or less worn. Most of the time, the wheel and rail work in wear and tear. There is not much research on the mechanics of locomotive after wear. Not wear factors can be ignored. But pay attention to this problem, still relatively few. Calculate the curvilinear motion of the locomotive, study the stability of locomotive motion, calculate the vibration, because the contacting process of the worn wheel and rail is not the same in size
