摘要:基于有限元分析方法,利用SolidWorks的实体建模和有限元分析模拟功能,建立了第二代汽车轮毂轴承法兰盘外圈的三维模型,而后进行网格划分得到离散化的有限元分析模型。针对第二代汽车轮毂轴承的实际应用情况,参照VW-5载荷谱,对建立好的有限元分析模型施加VW-5载荷谱中的最严苛的第18步载荷步的工况,计算分析得出法兰盘外圈的应力分布和轴向形变。结果表明,最大应力位于螺纹孔安装面上,其值为694.22 MPa,大于规定的塑性延伸强度,但小于该材料的拉伸强度,说明法兰盘外圈发生了不可恢复的塑性变形。轴向位移为0.357 mm,通过力矩刚性计算公式得出其力矩刚性为9.48′。

Abstract:Based on the finite element analysis method, using SolidWorks entity modeling and finite element analysis simulation function, established 3D model of generation second wheel hub bearing flange outer ring, and then to grid discretization of the finite element analysis model. In view of the practical engineering application, with reference to VW-5 load spectrum, applying the toughest steps 18th load condition of VW-5 load spectrum in flange outer ring, calculated and analyzed it to get that the stress distribution and axial deformation of the flange outer ring. The results show that the maximum stress is located in the installation on the threaded holes, the value is 694.22 MPa, it is more than the plastic elongation strength and less than tensile strength of the material, it shows have taken place unrecoverable plastic deformation in the flange outer ring. The axial displacement is 0.357 mm, and the moment rigidity is 9.48' by calculation formula.
