摘 要: | 以聚碳酸酯/丙烯腈丁二烯苯乙烯共聚物(PC/ABS)合金安全气囊软塑盖板为例,对其结构进行ANSYS有限元仿真分析和实物实验研究发现,H型和双 Y型2种气囊软塑盖板在爆破时能精准打开,但爆破时有碎屑产生。针对这一缺陷,提出了减小残余厚度,加入支撑块和盖板表面加入防滑筋2种结构优化方案,并对优化方案进行了验证分析。结果表明,2种优化方案均有助于减少PC/ABS合金安全气囊软塑盖板爆破时碎屑的产生。

Structural Optimization of PC/ABS Alloy Airbag Cover Plates |

Abstract: | This article reported a case study for the soft plastic cover plate made of polycarbonate (PC)/acrylonitrile-butadiene-styrene copolymer (ABS) alloys in terms of the structure analysis by ANSYS finite element method and experimental verification. The results indicated that the H-type and the double-Y-type air bag soft plastic cover plates could be opened precisely during the blast, but there were some debris generated. For this defect, two structural optimization schemes were proposed by reducing the residual thickness and adding supporting blocks and antislip strips on the surface of the cover plate. These optimization schemes were verified, and the results indicated that these two optimization schemes were helpful to reduce the generation of debris in the air bag flexible plastic cover plate made of PC/ABS alloys. |
