Design of Optimization of the Industrial Robot Forearm Topology
The forearm was an important load-bearing part of industrial robots.The forearm of an industrial robot with a load of 50 kg was taken as the research object,and it was carried out that the structural optimization design for additive manufacturing.Through topology optimization and model reconstruction,the material layout was optimized and the forearm structure was improved.Through the finite element analysis,the optimized forearm structural properties such as strain,stress and natural frequency were improved to varying degrees,at the same times the weight of the forearm was reduced by 22.12%,which realized the lightweight of the structure,reduced the operation energy consumption and the cost,and im-proved the life.It was conducive to green manufacturing.The topology optimization method had the value of popularization,and could provide reference experience for the optimization design and improvement of continuous structure.It helped the re-alization of digital design and intelligent manufacturing.
