作用于轮轨间的蠕变力,不仅担负着传送车辆驱动力和制动力的职责,同时也对车辆的曲线行车性能及车轮出轨等有着很大的影响。蠕变力对于了解铁道车辆行驶状况十分重要。到目前为止,针对蠕变力的特性已进行过各种各样的研究,但由于在蠕变力试验中存在滚动接触操作,所以通常在模拟 The creep force acting on the wheel and rail is not only responsible for transmitting the driving force and braking force of the vehicle, but also has a great influence on the driving performance of the vehicle and the derailment of the wheel. Creep force is very important for understanding the running condition of railway vehicles. So far, various studies have been conducted on the characteristics of the creep force, but because of the rolling contact operation in the creep test, it is common to simulate
