摘要
采用有限元分析软件ANSYS对焊接机器人大臂进行静力学和模态分析,得到大臂在最危险工况下的应力变化特性和固有频率及其对应振型,了解了大臂结构的薄弱环节,并对大臂进行拓扑优化设计,根据拓扑优化结果建立新的大臂结构,对最优结构的强度校核证明了设计方案的可用性与有效性。
The static and dynamic characteristics of the welding robot’ s arm was carried out by using AN-SYS based on FEM, the stress distribution and the natural frequency was obtained for a limit position. the weak links of the robot’ s arm was understood, and then the topological optimization was applied to the robot ＇s arm ,according to the results of the topological optimization ,the new robot＇s arm was established ,the in-tensity of the optimal structure proves the design scheme effectively and feasibly.
