The Topology Optimization Analysis Of YQ-1 Auto Trunk Inner Panel

The purpose of autobody components optimization design is to make designed structures who have lighter weight, smaller volume,lower cost,better reliability and so on. But autobody components are usually complicated,the results are not good using traditional experience formula method to optimize autobody components. However,with the rapid development of computer and numerical value method,some engineer problems whatever are simple or complicated can easily be resolved by discretized numerical value method and computers. Finite Element Method (FEM) is not only one important numerical value method,but also supplies a platform for structure analysis. As a way of structure optimizations for the topology optimization,because this method is very important during primary period of products design, in recent years people pay more attention to the technology of topology optimization design.HyperWorks , the structure Finite Element Method software is supplied by American Altair Software Corporation. This software is not only easy to use,but also has very powerful functions,especially for meshing technology and optimization functions. So,this software is very popular in home and abroad.This paper is a basic study for structure topology optimization design. Basing knowing about topology,structure topology optimization design,learning HyperWorks software, we study density method topology principle based on Finite Element Method in detail.
