英文摘要: |
Traditional bending machine design has the disadvantages of heavy structure. By using Pro/Engineer of 3D
design software and ANSYS Workbench, the bending machine topology was optimized. To reduce the weight, the
preliminary optimization model was designed based on the topology optimization. The thickness of the wall plate and
reinforced plates were optimized, and the final structural optimization scheme was confirmed. The final scheme met the
requirements of strength and stiffness. and the total mass was reduced. The study provides a design method that the
topology optimization combines with size optimization. |
