摘要

高速列车齿轮箱内的齿轮副的强度为列车安全运行的关键因素，以我国自主研发的某高速列车转向架齿轮箱齿轮副为研究对象，通过建立齿轮系统三维实体模型，通过SOLIDWORKS简化并建立有限元仿真模型，利用ANSYS WORKBENCH对齿轮啮合部位进行静态和瞬态力学分析。理论计算值和仿真分析结果都在强度安全范围之内，符合设计要求。在瞬态分析时发现，在齿轮启动阶段接触应力较大且出现应力波动，对齿轮系统的可靠性有一定的不利影响。

Abstract

The strength of the gear pair in the high-speed train gearbox is a key factor for the safe operation of the train, using China’s independent research and development high-speed train bogie gearbox gear as study object, three-dimensional gear system model was established, and finite element model was built by SOLIDWORKS simplifying, and with ANSYS WORKBENCH, static and transient mechanical analysis of gear meshing parts was carried out. Theoretical calculation and simulation results were both within the safe range of strength, and met the designed requirements. In transient dynamics analysis, it was found that there was some higher contact stress and stress fluctuation at the starting stage of the gear, which would have some adverse effects on the reliability of the gear system.
