机车动力 meaning in Chinese

railroad traction

When we do so we cannot get the detail distribution of system ' s stress and we are difficult to improve the structure as our wishes . wheel / rail system analyze is a typical elasticity contact problem , so we can use fem to analyse this system effectually . in this paper we used fem contact method analysed the system from engine kinetics standpoint
作为一种典型的接触问题，车轮轨道系统分析同时也属于机车动力的研究范畴，本文从机车动力学入手，对起重机车轮轨道的接触状态进行了动力学分析，在此基础上利用有限元接触问题的分析方法对起重机车轮轨道系统的接触应力进行了不同状态下的计算仿真。
