Abstract:Abstract: The bed of screw rotor grinder is a key force part, whose dynamic and static characteristics directly affect the whole machine’s processing accuracy and stability. To realize fast dynamic optimization design of the bed by ANSYS, the rib box parameters’ influence on the rib box’ dynamic characteristic was firstly analyzed based on the unit structure theory. Then the structural parameters of bed were optimized to increase natural frequencies and reduce bed weight. The feasibility of the comprehensive optimization scheme was verified through the static analysis. The results show that the bed’s dynamic performance is improved and the manufacturing cost is saved greatly: the first order natural frequency is increased by 22.3%, the bed weight is decreased by 8.39%, while the static stiffness is also increased significantly. The optimal method based on the unit structure can be also applied to the dynamic optimization design of other similar key parts.
