Dynamic Characteristic Analysis and Structural Optimization of Corrugated Wheel Based on ANSYS

车轮是保证城市轨道交通车辆安全、平稳运行的最重要部件之一，其再运行中产生的机械应力、制动热应力和声辐射功率都与车轮辐板的几何形状有密切关系。其中，波形辐板车轮是国际铁路联盟UIC标准规定得标准车轮形式。波形辐板车轮辐板几何形状的优化设计可以使得用较少的材料尽可能提高轮对的承载能力和运行寿命，本设计运用SOLIDWORKS三维软件对列车车轮进行了三维建模，运用ANSYS分析了波形辐板车轮在典型工况下的应力分布状态受车轮几何形状主要参数的影响规律。通过对轨道交通车辆车轮进行有限元模拟，基于列车制造和运行中产生的应力对波形辐板车轮几何形状进行优化设计。为日后对波形辐板轮对的动力特性的研究提供了指导。
Wheel is one of the most important components to ensure the safe and smooth operation of urban rail transit vehicles, and the mechanical stress, braking thermal stress and acoustic radiation power generated during its operation are closely related to the geometry of the wheel spoke plate. Among them, the corrugated wheel is the international railroad union UIC standard stipulates the standard wheel form. The optimized design of the spoke plate geometry of the corrugated wheel can make use of less material to improve the load carrying capacity and operating life of the wheel set as much as possible, this design uses SOLIDWORKS three-dimensional software to carry out three-dimensional modeling of the train wheel, and uses ANSYS to analyze the distribution of stress in the corrugated wheel in the typical working conditions by the influence of the main parameters of the wheel geometry law. Through the finite element simulation of the wheels of rail transit vehicles, the optimized design of the wheel geometry of the corrugated wheel is based on the stresses generated in the manufacture and operation of the train. The optimized design of the wheel geometry is based on the stresses generated during train manufacturing and operation, which provides guidance for the future research on the dynamic characteristics of corrugated wheel pairs.
