Modal Analysis of the Line Inspection Robot's Manipulator

Abstract:

The Line Inspection Robot is used to detect the line's defects when it walks on the overhead lines. It will be swinging under its own vibration and the action of wind , due to the robot arms hanging on overhead line alone ,so the dynamic characteristics of robot arm cannot be ignored. In this paper, we establish three-dimensional models of the line inspection robot's manipulator with double manipulators of antisymmetric structure, and conduct solving and post-processing of statics and modal analysis after meshing and applying constraints. The manipulator's low frequencies and vibration modals are drawn, so we can provide a theoretical basis for the reasonable optimization improvements to the line inspection robot's manipulator with double manipulators of antisymmetric structure.
