Structural Optimization and Lightweight Analysis of Industrial Robot Arm
Abstract
Industrial robots play an increasingly significant role in modern manufacturing. The robotic arm, as one of the key components,
holds considerable value in the research on its structural optimization and lightweighting. In this paper, the ER20-C10 six-degree-of-freedom
industrial robot arm is taken as the research object. By adopting the orthogonal experimental design method and in combination with topology
optimization technology, the optimization paths of the robotic arm in terms of strength, stiffness, dynamic characteristics, and lightweighting
are thoroughly explored. Finite element analysis is employed to compare different optimization schemes, ultimately achieving the lightweighting of the robotic arm structure while ensuring structural safety and enhancing mechanical performance.
