Topology optimization is one of the most important methods of structure optimization, which is to optimize the weight and performance of the structure by changing the distribution of materials. Firstly, this paper introduces five main methods of topology optimization: homogenization method, variable density method, progressive structure optimization method, independent continuous mapping method and level set method. Then, the development process, optimization principle and effect of each method in practical application are elaborated. Based on the theoretical basis of these methods, the advantages and limitations of these methods in different situations and practical applications are analyzed and compared. In addition, the applicability of these methods in different scenarios is summarized, and their effects and limitations in solving specific engineering problems are pointed out. Finally, the future research direction of topology optimization and some potential improvement measures are proposed to find better solutions in complex engineering problems. The research results show that each topology optimization method has its own advantages and disadvantages. Each method is suitable for different application scenarios, so it is necessary to choose the appropriate method according to the specific needs.
