| Abstract: | It was researched and analyzed the realization scheme of lightweight manipulator structure，established the topology optimization model of the manipulator through the variable density algorithm provided by Patran software，analyzed the topological structure of the boom according to the pre-divided design area，and implemented the topology optimize the solution，and finally output the topology optimization result.On this basis，the topological optimization results of the mechanical arm were analyzed through the stress cloud chart of the mechanism arm and the displacement cloud chart of the mechanism arm.The experimental study found that the maximum stress and maximum displacement of the mechanical arm before and after the topology optimization did not change significantly，and the change of the mechanical arm topology did not affect its physical performance.The masses of the boom before and after the topology optimization were 2.092 kg and 1.777 kg，the mass of the boom was reduced by 15.06%.In addition，the speed fluctuations of the joints of the manipulator arm during operation had also been improved accordingly，showing a significant optimization effect. |
