基于NX NASTRAN的客车驱动桥桥壳有限元分析

摘要

The 3D model for drive axle housing is established in UGS NX, for finite element analysis with NX NAS-TRAN. The stress and deformation distribution of components are worked out through static analysis under typical working conditions. The impact load generated between the automotive wheels and the ground during driving will cause deformation or even breakage of the axle housing. The finite element analysis is performed for drive axle housing, providing reference for technical improvement of manufacturing and machining, etc. , for the purpose of improving the product quality.%在UGS NX中建立了三维驱动桥桥壳模型,并采用NX NASTRAN对其进行有限元分析.通过对其典型工况下的静力学分析,得出零件的应力及变形分布.汽车在行驶过程中车轮与地面间产生的冲击载荷会引起桥壳变形甚至出现折断现象.对驱动桥桥壳进行有限元分析,可为其制造加工等的技术改进提供参考,从而提高产品质量.
