摘要
2012版CNCAP偏置碰撞速度增加到64 Km/h,加大了此部位的得分难度;假人胸部伤害值与约束系统的参数紧密相关。利用Mode Frontier分析软件,在头颈部伤害值不超标的情况下,通过调整安全带与气囊的关键参数(气袋排气孔直径、安全带限力值、气囊点火时间)来优化分析胸部伤害值,使得胸部尽量多得分。该项研究可为整车约束系统开发工作提供一定的理论参考。
The speed of 40% Offset Impact is increased to 64Km/h in 2012 CNCAP, making it more difficult to score. The damage value of dummy chest is closely related to the parameters of the constraint system. In this paper, using the Mode of Frontier analysis software, in the case of head and neck injury values are not overweight, by adjusting the key parameter of seat belts and airbags （air pocket vent diameter, seat belt strength, airbag ignition time limit） to optimize analysis chest damage, make bosom score as much as possible. This research can provide some theoretical reference for the development of vehicle restraint system.
