Abstract

High temperature exists in the process of coding robot for hot-rolled steel. This article uses ANSYS for thermal analysis, stress analysis and thermal-stress coupling analysis to solve the high temperature problem of the hot-rolled steel. This article studies the temperature distribution, deformation and stress of the coding robot and ensure the robot to work safely and reliably. Solid Works software is used to build the three-dimensional model of the coding robot, and ANSYS software is used to analyze the coding robot in three positions and postures, also to solve the temperature distribution. Secondly, the position of maximum displacement and maximum stress is found by stress analysis. This article uses ANSYS for modal analysis to solve frequency and mode shape of the coding robot. Finally, the real working condition of the robot system under the simultaneous action of high temperature and load are simulated and changes of stress and displacement in the coupled thermal-stress field are analyzed. The results show that the coding robot meets the requirements of stiffness and strength and it can work normally. In the coupled field, the deformation of the coding robot is slightly smaller than that of the static analysis, as well as the thermal radiation has less influence on the stress of the coding robot.
