多臂节机械臂架系统连杆组参数化建模及优化设计

针对多臂节机械臂架系统连杆计算效率不高,优化设计手段保守的问题,以混凝土泵车臂架作为典型工程装备部件,将臂节之间的油缸及连杆作为整体考虑成连杆组,利用ANSYS APDL语言对连杆组进行参数化建模,并在多工况下进行优化分析,得到连杆组的最优结构模型;通过结构应力试验,验证了计算方法的可行性.结果表明,参数化建模及优化设...

Link Group Parametric Modeling and Optimal Design in Multi-arm Mechanical Arm System

Aiming at the problems of low calculation efficiency and conservative optimization design method of link in multi-arm mechanical arm system,taking the concrete pump truck as a typical engineering equipment component,the cylinder and link between the arm units are considered as one link group,the ANSYS APDL language is applied for the parametric modeling,and the optimization analysis is carried out under multiple working conditions,the optimal structure model of the link group is obtained.The feasibility of the calculation method is verified by the structural stress test.The results show that,the calculation efficiency of links is greatly improved with the methods of parametric modeling and optimal design,a feasible and effective method is provided for the design of links in the multi-arm manipulator system,and an important reference is provided for the design of components with similar structures.
