Topology optimization and structural reconstruction design of manipulator shell of rescue robot for power transmission line

Electric Machine Design and Control > Electric machine design

The lightweight structure of the rescue robot for high-voltage transmission lines is the key to its practical stage. This paper takes the high-voltage power transmission line rescue robot manipulator shell as the object, takes the minimum structural quality as the goal, and takes the rigidity as the constraint conditions. The topology optimization design of the structure is carried out, and the three-dimensional topology of the shell structure is obtained. According to the optimized topology, the three-dimensional structure of the manipulator shell is reconstructed and the finite element force is verified and analyzed. By comparing the force analysis results before and after reconstruction, the mass of the reconstructed manipulator shell is reduced by 41.40% under the conditions of structural strength and rigidity. The research ideas and results of this article can provide ideas for the pro-quantitative design of other structures of the rescue robot on the transmission line.
