In order to meet the requirement of spiral welding rod production line, a truss robot was designed to automatically carry pipe in the process of welding. Aiming at the problem of stiffness of robot body and the stability of truss robot, static analysis of robot body was carried out which shows that the deformation of body had little effect on the positioning accuracy of the robot. And modal analysis of the robot which proves that the lowest natural frequency is higher than the robot excitation frequency was conducted. Finally, in order to further improve the dynamic performance of the whole machine, some suggestions for improving the structure of linear motion module were put forward. The method provided a scientific basis for the structural design of the truss robot.
