Abstract: Aimed at the problems that the multi-workstation revolver of ultra high-speed packaging machine had high motion inertia impact and high structure dynamic characteristics under the condition of large dead weight, ultra high-speed rotation and complex multi-workstation load. The paper analyzed the working load and constraint condition of multi-workstation revolver under rated working condition, and the finite element analysis model was constructed by using ANSYS Workbench platform, and the optimal topology optimization material distribution characteristics of multi-workstation revolver in the design domain was calculated with topology optimization technology, and based on the topology optimization density map and 3D model, two optimized schemes were constructed by the structure scheme of gradient ring band and stiffener and the structure scheme of gradient arc groove and weight reduction hole respectively with symmetric structure. The results showed that the structure scheme of gradient ring band and stiffener is optimal, which can be meet the static and structural natural frequency requirements under proper working load at the same time,compared with the prototype design,the quality of the optimal structure scheme is reduced by 16.33%, and the maximum equivalent stress of the optimal structure scheme is reduced by 11.25%, and the dynamic specific stiffness efficiency of the optimal structure scheme is increased by 4.14%.
