摘　　要：从优化的角度来评估倒角形状对某转台外框的影响程度,首先根据静动态特性,用优化准则法实施拓扑优化,得到满足要求的最少材料分布,为倒角优化提供可行性;接着在参数化建模的基础上对圆倒角半径进行了尺寸优化,先采用随机搜索法获得可行解,再用函数逼近法进行寻优,以得到倒角大小对结构的影响规律,对同类结构的设计具有指导和借鉴意义。Chamfer shape is assessed from the viewpoint of optimization on the structure of outer frame of simulating turntable.Firstly,based on static and dynamic behaviors and by using the method of optimality criteria to implement topological optimization,the least material distribution that meets the requirements was obtained,providing feasibility for chamfer optimization.Then,on the basis of parametric modeling,the size optimization was carried out,the feasible solution was found by applying random searching technique.After optimizing by using the function approaching method,the rule of the influence on the structure by the amount of the chamfer was found.The conclusion provides a guide and reference for design of similar structures.
