Optimization Design for Link Structure of Heavy-Duty Transfer Robot Based on Response Surface Method

In this paper, the statics analysis of the heavy-duty transfer robot is first performed to determine the maximum stress of each link in the dangerous position. The minimum mass of each arm is taken as the optimization target, and the strength conditions and deformation are the constraint conditions. Using the target optimization function of ANSYS Workbench, the thickness and width of each arm are optimized. And based on the optimized arm structure size, the robot structure is designed. The results show that the optimized mass of the forearm and the forearm support link is decreased by 24.66% and 28.71% respectively, so the lightweight of the heavy-duty transfer robot is realized.
