某发动机主轴承盖轻量化设计

Lightweight Design on Main Bearing Cap of an Engine

发动机零部件轻量化设计主要有2种途径,一种是更改材料,另一种是结构优化设计。针对某发动机主轴承盖进行轻量化结构设计,基于Abaqus对主轴承盖组件进行有限元仿真,分析主轴承盖的疲劳强度,然后对主轴承盖进行结构优化并进行仿真分析,获得主轴承盖最优设计方案。

There are two main ways in lightweight design of engine parts,one way is to change the material,the other one is structure optimization design.In this paper,we make lightweight structure design on main bearing cap of one engine.The finite element simulation of the main bearing cap is performed by Abaqus,and the result of fatigue on the main bearing cap is analyzed.After optimizing the main bearing cap structure and simulation analysis,the best project is obtained.
