摘要

针对传统建模方法下汽车传动系统中非规则壳体部件有限元分析结果不准确的问题,提出一种基于部件简化的有限元新型建模方法。详细给出了轴承、齿轮和紧固件等常用部件的模型简化方法,并以汽车主减速器壳体有限元分析为例,基于有限元软件环境,建立了基于传统建模方法和文中提出方法下的两种有限元分析模型;通过对两种模型的仿真结果对比发现:两种方法下汽车主减速器壳体上应力分布总体趋势相同,但是在安装轴承位置等局部区域应力值相差较大。通过对主减速器在输入扭矩为100 N·m,200 N·m和400 N·m三种工况下壳体应力的测试得知:简化方法建立的模型分析结果更加接近实际数值,从而验证了所提方法的正确性和准确性。

Abstract

The problem of inaccurate results was presented based on irregular shell finite element analysis using traditional modeling methods,a finite element modeling method was presented based on simplified of transmission components. The paper introduced the bearings,gears and fasteners of simplified model method. For example,finite element analysis of automobile main reducer shell based on finite element software environment. Two finite element analysis models were established based on traditional method and simplify component method; Comparing simulation results of the two models found: stress distribution on the overall trend of automobile main reducer Shell was the same,but the value of the local area to install the bearing stress positions were quite different. Stress tests show in 100 N. m,200 N. m and 400 N. m of input torque main reducer: Simplified model approach closer to actual value of test results,verify the correctness and accuracy of the method.
