| 摘 要： | 镁合金作为轻量化材料,应用到汽车零部件中可以实现较大幅度的减重效果。而镁合金挤压型材在汽车零部件设计中的应用较少。将镁合金挤压管材作为后排座椅骨架的基本型材,通过多次弯曲得到座椅骨架,并基于Dynaform软件,对挤压管材的各段弯曲部位进行仿真,得到具有工艺可行性的弯曲半径设计。对新设计的镁合金座椅进行动态行李保持仿真,结果表明新设计的镁合金座椅能承受行李对其的动态冲击。

| Abstract: | As a lightweight material,the magnesium alloy can be applied to automobile parts to reduce weight effectively. But,its extruded section bars are rarely used in automobile part design. These section bars are bended several times to form the car's seat back frame. The bending process is simulated by Dynaform to obtain the feasible bending radius. The dynamic luggage keeping simulation shows that the new seat back frame can be subjected to the dynamic impact of luggage. |
