During the topology optimization of the load pan, the combination of the homogenization and artificial density method is adopted, and the concept of density subjection function and relative density is introduced, consequently, the traditional topology optimization issue is transformed to the optimum distribution of materials 在对负载盘进行拓扑优化设计的过程中,本文采用了均匀化法和变密度法相结合的方法,引入了密度隶属函数和相对密度的概念,从而将传统意义上的拓扑优化问题转换为材料的最优分布问题。
