Optimizing of vertical lathe sliding pillow based on TRIZ/DOE

Abstract

Aim to reduce the deformation of sliding pillow in vertical lathe, related literature are reviewed and find that parameter optimization design method is widely used. However, this method is in essence to compromise the design parameters and does not eliminate the design conflicts. Therefore, the combination of TRIZ and parameter optimization design method is proposed to solve this problem. Our job include next three steps. Firstly, the framework of parameter optimization design combined with TRIZ is proposed. Secondly, the flowchart of combining TRIZ with parameter optimization design is established. Finally, the proposed method was applied to redesign the sliding pillow. ANSYS Workbench software was used to optimize the design, and lightweight and reducing deformation were taken as the design objectives. The simulation results show that, compared with the original design, the sliding pillow deformation is reduced by 17.049%, and the proposed method extends the conceptual solution space of the simple parameter optimization design method.
