摘要
约束系统是汽车被动安全的重要组成部分,为提高约束系统的有效性,以Hybrid III 50th男性假人在100%重叠正面碰撞工况下的得分为基础进行多学科优化分析,得到了安全带及安全气囊参数与假人胸部、小腿之间的变化关系。并通过调整安全带和安全气囊参数,得到了最优参数匹配,使假人得分从14.12分提高到14.46分,有效提高了假人得分,对约束系统参数设计具有一定的参考意义。
Restraint system is a significant component of vehicle passive safety.In order to improve the effectiveness of the restraint system,multidisciplinary optimization analysis has been completed based on the score of Hybrid III 50th male dummy under 100%overlapping frontal impact condition.The relationship between the parameters of safety belt and airbag and the dummy chest and lower leg was obtained.And the optimal parameter matching was obtained by adjusting the parameters of seat belt and airbag.The dummy score was increased from14.12 to 14.46,which effectively improves the dummy score.It has a certain reference significance for the parameter design of restraint system.
