由于磨损引起的车轮和轨道轮廓的改变涉及相当大的车辆和轨道维护成本，并且影响轨道的承载能力以及车辆的操作安全性和乘坐舒适性。在过去的二十年中，出现了基于车辆动力学、接触力学和摩擦学的研究工作，最近在国际范围内也在持续进行，并且这项研究越来越深入。随着计算机分析的可能性越来越大，已经详细阐述了几种算法和数值程序，以及基于测量的实验已经进行，以建立对磨损引起的车轮和钢轨轮廓变化的可靠预测，并通过选择用于在特定的-在通常固有随机的交通条件下。本文试图介绍一种新的电子...
SUMMARY The alteration in wheel and rail profiles due to wear involves considerable vehicle and track-maintenance costs, and influences the loading capacity of the rails, as well as the operation safety and riding comfort of the vehicles. In the past twenty years a vehicle dynamics, contact mechanics and tribology based research work has emerged which is also recently continuous in an international scale, and this research is more and more intensive. Parallel to the growing possibilities of computer based analyses, several algorithms and numerical procedures have been elaborated, as well as measurement based experiments have been carried out to establish the reliable prediction of wear-caused wheel and rail profile alterations and to maximise the mileage performance by selecting the optimum vehicle system parameters for running gears operating on a selected railway line or a whole network under specified -in general inherently stochastic - traffic conditions. This paper takes an attempt to introduce the e...
