Through structure optimal design,the aim of light-duty design of the electronic frame is achieved by the method of combining finity element analysis with test.

Research on lightweight design of BIW of some car

Technology charac- teristics of SiC mirror on lightweight design,mirror blank fabrication,SiC coating,optical machining and optical test- ing are introduced.

According to the requirements of lightweight design in a new vehicle development,an improvement design is conducted on the original body structure with the mass of front-end structure reduced.

An integrated method of topology optimization and shape optimization was presented to study the application of structure optimization to the light-weight design of engine block.

To implement the light-weight design for an engine support,the finite element model of its local support is established based on the global structure finite element analysis of support assembly according to equal rigidity principle,and the support displacement distribution results under different loading cases are obtained.

A variable density based topology optimization method was applied to the light-weight design of engine block.

The research indicates that the topology optimum design by way of FEA is a highly efficient optimum method,which may provide valuable conceptual light weight design idea for mechanical structures and parts in the process of preliminary design stage.
