Abstract

以最新研制的搅拌摩擦焊机器人为例,建立了一套针对于大型重载高精度设备的结构设计分析流程。为了提高机器人的焊接精度和评估重要零部件的力学性能,建立了搅拌头的力学模型,并进行了焊接过程的数值仿真,精确地模拟了机器人在5种典型工况下的受载状态,获得了整机刚度和强度的结果数据,最终有效地指导了整个机器人的结构设计。结论表明:搅拌摩擦焊机器人在最恶劣构型瓜瓣焊工况下刚度性能良好,各主要功能元器件安全可靠,整机的刚度性能能够满足给定的焊接指标,为整机的轻量化设计和力学性能优化创造了条件。

Other Abstract

Considering the latest developed Friction Stir Welding (FSW) robot, a set of structure design analysis process is established for large-scale equipments of heavy-loading and high precision. The FSW robot is characterized by large volume, complicated structure and extremely bad working conditions. In order to improve the accuracy and evaluate the mechanical property of the welding joints, the mechanical model of the FSW head is built and the welding process under five working conditions is simulated. The obtained forces and torques can be taken as the boundary conditions for robot strength and stiffness analyses; and the analysis results can be used to verify the rationality of structure design of the robot. Simulation results show that the stiffness performance of the robot is good under the most severe welding condition of melon-segments configuration; all the functional components are safe and reliable, and the structure design of FSW robot meets the welding quality requirement. The results may provide references for further lightweight design and mechanical performance optimization of the FSW robot.
