基于Creo和Inspire的工业机器人末端执行器结构拓扑优化设计

Structural Topology Optimization Design of Industrial Robot End Effector Based on Creo and Inspire

为了在不降低力学性能的情况下实现轻量化设计,在对某工业机器人末端执行器的手指结构的使用工况和边界条件进行分析的基础上,利用Creo 7.0软件完成该手指结构的三维建模,借助Altair Inspire 2020软件先进的有限元优化求解器对手指结构在设定条件下进行拓扑优化设计和结构强度校核,在兼顾制造工艺的基础上获得手指结构的最优设计方案。拓扑优化后的手指零件质量减小了43.85%,使用上述方法进行产品结构设计,在第一时间就能实现降低开发成本、缩短产品开发周期、减少材料消耗和减轻产品重量。

In order to achieve lightweight design without reducing mechanical properties,based on the analysis of the working conditions and boundary conditions of the finger structure of an industrial robot end effector,the three\|dimensional modeling of the finger structure is completed by Creo 7.0 software.With the help of the advanced finite element optimization solver of Altair Inspire 2020 software,the topology optimization design and structural strength check of the finger structure under the set conditions are carried out,and the optimal design scheme of the finger structure is obtained on the basis of considering the manufacturing process.After topology optimization,the finger part mass is reduced by 43.85%,so that the product structure design can solve the problems of reducing development cost,shortening product development cycle,reducing material consumption,and lightening product weight at the first time.
