Optimization Design for the Rib Plate Structure of the Workbench of a Electric Discharge Wire Cutting Machine Tool
In order to improve the static and dynamic performance of electric discharge wire cutting machine tools,an optimization design method for the structure of workbench rib plate is presented.Rib plates,with different shapes and densities,at the bottom of the workbench are designed,and the shape of the rib plate with optimal static and dynamic performance is obtained through comparing workbenches to rib plates with the same density and different shapes.Comparing rib plates with different densities and shapes on workbenches,the appropriate rib plate density is obtained.After converting the volume of the cut part into the volume of the designed rib plate,the rib plate with the optimal shape and density is found,and the appropriate rib plate height is solved further.The size optimization design of the rib plate is carried out to achieve lightweight of the workbench.The research results show that the proposed optimization design method of the workbench rib plate structure is feasible and the static and dynamic performance of the designed #-shaped rib plate workbench is relatively optimal.After optimization,the mass of the workbench is reduced by 2.28％compared to the original workbench,the maximum total deformation is reduced by 3.00％,the maximum equivalent stress is reduced by 5.28％,and the first order natural frequency is increased by 4.99％.
