In order to make the robotic arm of the palletizing robot respond to the control instruction faster,improve the movement speed,increase the flexibility,and reduce the energy consumption,the lightweight design of the boom part was carried out under the condition of ensuring that the strength and stiffness of the boom part of the palletizing robot meet the requirements.Based on Altair Inspire lightweight design software,the geometry of the boom part of the palletizing robot was reconstructed to find the optimal distribution position of material and remove unnecessary material.Under the condition of satisfying the minimum safety factor,the mass of the boom part is reduced as much as possible,so as to achieve the lightweight goal.The result shows that under the premise of satisfying the displacement,equivalent stress and minimum safety factor,the mass of the boom part of the palletizing robot is reduced by 80％,and the motion performance is improved,which provides a reference for the subsequent lightweight design of the palletizing robot.
