| 中文摘要: |
| 针对传统形貌优化技术的起筋只能沿板件法向正方向的局限性，应用空间多层形貌优化技术解决了该问题，结合工艺可行性、结构功能及性能等要求，对车门内板进行结构轻量化设计，并进行了实车门刚度台架试验验证。在不增重的前提下，提高了扭转刚度，满足了车门设计目标要求，实现了车门轻量化设计。 |
| 英文摘要: |
| Aiming at the limitations of traditional morphology optimization technique that rib was generated only along the positive direction of plate normal, space multi layer topography technology was applied to solve this problem. The door lightweight optimization design was conducted based on torsional stiffness, bonding process feasibility, structure, function and performance requirements etc. A real door stiffness bench validation was done. It is proved that the torsional stiffness is promoted and the objectives and requirements are achieved, under the premise of not increasing weight. |
