Abstract：

In order to study the static properties of the gantry bending machine and its anti-vibration performance of frame during full load operation, pre-stress modal analysis of a gantry bending machine frame was processed using ANSYS Workbench. The static analysis results and the first six orders of natural frequencies and corresponding vibration modes of vibration were obtained. Using topology optimization, the shape of removed material for the bending machine workbench was optimized. The workbench model was reconstructed in SolidWorks after the shape was resized according to the topology optimization nephogram. The optimized model was imported into ANSYS Workbench again for pre-stress modal analysis, and the static properties and dynamic characteristics of the frame before and after optimization were compared and analyzed. The weight of the final workbench was reduced by 11.7%. The maximum equivalent stress was also reduced. And the anti-vibration performance of the gantry bending machine was not affected. The feasibility of topology optimization was determined.
