Locomotive-track interaction is a multidimensional task because it goes in many directions depending on the aim of the investigation. One such direction relates to wheel or track damage produced by traction and braking of locomotives under different train operational scenarios. The best option for performing wheel or track damage studies is to use the Exact theory developed by Kalker directly in the simulation procedure to solve the contact mechanics task at the wheel-rail interface. In this paper, a specially developed wheel-rail coupling is presented based on the Extended Contact library and incorporated in a full mechatronic model of a modern heavy haul locomotive. The implementation of the parallel computing technique in the locomotive model development allows for achieving reasonable computational performance. Thereby, this complex approach shows a perspective for competing with the standard approach that uses a sequential computing technique or combined study approaches, while at the same time providing accurate results that are required for locomotive/track damage studies.

机车-轨道交互是一项多维任务，因为它根据调查的目的在多个方向上进行。一个这样的方向涉及在不同列车运行情况下由机车的牵引和制动产生的车轮或轨道损坏。执行车轮或履带损伤研究的最佳选择是直接在模拟过程中使用 Kalker 开发的精确理论来解决轮轨界面处的接触力学任务。在本文中，基于扩展接触库提出了一种专门开发的轮轨联轴器，并结合到现代重载机车的全机电一体化模型中。在机车模型开发中实施并行计算技术可以实现合理的计算性能。从而，
