Taking variable density method as material interpolation,the minimal compliance as the objective and optimization criterion as the optimal algorithm,this paper described the process of topology optimization of microstructure by using finite element technology.The topology optimization with the products of low voltage apparatus was carried out.The results show that the quality of parts structure is greatly reduced with topology optimization,while the performance is ensured at the same time.Thus an effective scheme of cost reduction is provided.
