Abstract： In order to solve the application problems of topological optimization technology in reality，the bicycle frames and multiple arch bridge was investigated.After the analysis of all kinds of methods of topological optimizaiton，the mathematical model that unit material density as design variables，the minimum of structural compliance as the objective function，the volume reduction percentage as the constraint function was established. The topology optimization design module of the commercial finite element software ANSYS was used to the bicycle frame and multiple arch bridge for the topology optimization design.The topological structure is clear and they are very likely to the bicycle frame and multiple arch bridge in reality. The results indicate that the method is correct and effective，it has a certain engineering application prospect.
