摘要
以棉桶更换机器人为研究对象,采用Solidworks对机器人进行建模与装配,获得了总体设计模型;采用ANSYS Workbench软件,分析了棉桶更换机器人整机在最大载荷情况下最远端位姿的静力学特征,得到整机在工作空间内的应力云图和位移云图;综合研究机器人强度和刚度分布特性,指出腰部的回转支架是其薄弱环节所在;提出通过加厚回转支架底部的加强筋,可以在一定程度上减小机器人最大等效应力和最大等效位移,从而进一步提高机器人的结构性能。
The general design model is attained taking the cotton barrel replacement robot as the research object using Solidworks to model and assemble the robot. The stress contour and displacement contour of the robot in workplace were obtained by analyzing the static characteristics of the cotton barrel robots terminal position under the maximum load condition using the ANSYS Workbench software. The fact that the lumbar rotary bracket is the weakest link was indicated after an integrated research of the distribution characteristics of the robot strength and stiffness. The conclusion is drawn that the maximum equivalent stress and displacement of the robot can be reduced to some extent by thickening the stiffening rib on the bottom rotary bracket and this can further improve the structure properties of the robot.
