车辆系统动力学（包括在附着极限下行驶时的驱动动力学和牵引力控制）的复杂仿真的必要条件是考虑大的纵向蠕变的先进蠕变力建模。本文提出的方法可以用一个参数集模拟各种真实的轮轨接触条件。这些参数可以从测量中识别，或者可以使用工程应用中典型轮轨接触条件建模的推荐参数。还考虑了车辆速度、纵向、横向和自旋蠕变以及接触椭圆形状的影响。通过与应用实例中的测量结果进行比较，验证了该方法的有效性。(C)2004 Elsevier B.V.保留所有权利。
A necessary condition for complex simulations of vehicle system dynamics including drive dynamics and traction control when running on adhesion limit, is an advanced creep force modelling taking large longitudinal creep into account. A method presented in the article allows to simulate various real wheel-rail contact conditions using one parameter set. The parameters can be identified from measurements or the recommended parameters for modelling of typical wheel-rail contact conditions in engineering applications can be used. Influence of vehicle speed, longitudinal, lateral and spin creep and shape of the contact ellipse is also considered. The method was validated by comparisons with measurements as presented in application examples. (C) 2004 Elsevier B.V. All rights reserved.
