摘要: 为了减轻汽车座椅背板重量,采用玻璃纤维复合材料替代金属材料,通过仿真与试制件测试检验轻量化效果。建立金属和玻璃纤维复合材料背板模型,根据GB 15083—2019标准进行碰撞仿真分析,结果均满足要求。使用模注一体化成型工艺生产玻璃纤维复合材料背板件,重量为5.04 kg,相比金属(铁)背板(7.31 kg)减重31.05%。通过摆臂碰撞试验,实测玻璃纤维复合材料背板变形与仿真变形最大相对误差为3.2%,仿真结果可靠,碰撞后玻璃纤维复合材料背板未发生失效且仍保持在原锁止位置,满足标准行李箱冲击试验要求。玻璃纤维复合材料背板达到了预期的轻量化效果。

Abstract: In order to reduce the weight of car seat back panels, glass fiber composite materials are used instead of metal materials, and the lightweight effect is verified through simulation and trial production testing. Establish models of metal and glass fiber composite back panel, collision simulation analysis is conducted according to GB 15083—2019 standard, and the results meet the requirements. The glass fiber composite back panel was producted by using integrated injection molding process, weighing 5.04 kg, which achieved a weight reduction of 31.05% compared to metal (iron) back panel weighing 7.31 kg. Through the swing arm collision test, the maximum relative error between the measured deformation and simulated deformation of the glass fiber composite back panel was 3.2%, and the simulation results were reliable. After the collision, the glass fiber composite back panel did not fail and remained in its original locking position, meeting the requirements of the standard luggage impact test. The glass fiber composite back panel achieved the expected lightweight effect.
