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。
Aiming at the limitations of traditional morphology optimization technique that rib was generated only along the positive direc- tion 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.
