铸件切割打磨机器人工作臂关键部件有限元分析

为保证铸件切割打磨机器人工作臂关键部件强度和零件材料选择的合理性,运用ANSYS Workbench软件对铸件切割打磨机器人工作臂关键部件进行静力学分析,有限元分析结果表明:砂轮切削打磨装置进行曲面切削打磨,承受左三向力极限载荷时,最大位移变形量为0.29332mm,发生在打磨头;最大等效应力为85.45MPa,发生在打磨头与打磨头固定位置左上侧,即结构强度和刚度满足砂轮切削打磨装置工作要求,为铸件切割打磨机器人结构设计和强度校核提供了参考。

Finite Element Analysis of Key Components of the Working Arm of Casting Cutting and Grinding Robot

In order to ensure the rationality of the strength and material selection of the key components of the working arm of the casting cutting and grinding robot,the static analysis of the key components of the working arm of the casting cutting and grinding robot was carried out by using ANSYS Workbench software.The results of the finite element analysis show that the maximum displacement deformation of the grinding wheel cutting and grinding device is 0.29332 when it is subjected to the limit load of the left three-way force The maximum equivalent stress is 85.45MPa,which occurs at the upper left side of the fixed position between the grinding head and the grinding head,that is,the structural strength and stiffness meet the working requirements of the grinding wheel cutting and grinding device,which provides a reference for the structural design and strength check of the casting cutting and grinding robot.
