摘要
针对薄壁件定位支撑结构的优化设计问题,建立了以刚度为目标函数,以体积为约束函数的拓扑优化模型。将支撑材料与工件看作同一实体,采取多组件多约束的拓扑优化方法,利用Ansys软件中的拓扑优化设计模块对环形薄壁件的定位支撑结构进行拓扑优化分析。并对不同加工条件的仿真结果进行了比较,得到了切削力大小和方向、优化参数与系统刚度以及工件变形的关系。
Aiming at the design of workpieces positioning structure, the topological optimization model was established, in this model, the stiffness is used as target function and volume as restraint function, and the supporting materials and parts is treated as the same entity, the multiple component and constraint method are adopted. Then using Ansys software, compared the different results, and got the relationship of the cutting force magnitude and direction, the optimized parameters and system stiffness and distortion. The results for cutting process optimization has certain effect.
