The Welding Robot Arm Optimization Based on APDL

Abstract

Ontology stiffness of welding robot has an important effect on its positioning accuracy. Based on the parameterized model of the arm built with the software of ANSYS, this paper optimized the robot arm mass of the welding robot in method of first-order using the ANSYS parametric design language (APDL). The lightest mass of the arm was obtained on the premise of the stiffness requirement of the welding robot. From the results, we could assume that the first-order method was a scientific and accurate optimization method, which provided the theoretical direction of optimization as for the welding robot structure.
