基于车用轮毂轴承接触仿真与模态分析

Based on the Contact Simulation and Modal Analysis of the Vehicle Wheel Bearing

对于目前车用轮毂轴承实际广泛应用,需要对车用轮毂轴承具有更深入的参数评价,以车用轮毂轴承作为研究对象,建立三维立体实体模型,导入Workbench进行有限元分析。根据国家标准的轴承极限载荷和转速下,得到车用轮毂轴承在径向载荷作用下的形变情况与接触应力、应变大小分布。有限元仿真结果表明轴承形变和应力、应变主要分布在车用轮毂轴承内、外滚道,以及对该轴承进行模态分析给予轴承旋转时振动特性。

For the current wide application of automotive wheel bearings,it is necessary to have a more in-depth parameter evaluation of automotive wheel bearings.With automotive wheel bearings as the research object,a three-dimensional solid model is established and imported into Workbench for finite element analysis.According to the national standard bearing limit load and speed,the deformation and the distribution of contact stress and strain of the vehicle wheel bearing under radial load are obtained.The finite element simulation results show that the deformation,stress,and strain of the bearing are mainly distributed in the inner and outer raceways of the automotive wheel bearing,and the modal analysis of the bearing gives the vibration characteristics of the bearing during rotation.
