摘要
为了减少乘员在碰撞事故中的伤害,提高座椅的安全性能,结合GB 11551规定性能对座椅结构进行优化设计。分析了座椅子系统台车正碰试验时座椅的传力路径,确定了对假人H点前移量及下潜量有影响的参数及结构,通过正交试验的方法系统分析了各因素对性能的重要程度,同时,提出了一种综合考虑座椅防下潜性能与乘坐舒适性的设计方法,给出了座椅安全性能及舒适性相平衡的设计方案。
In order to reduce the injury of occupants in collision accidents and improve the safety performance of seats,according to GB 11551 regulation performance,optimize the design of seat structure.This paper analyzes the force path of seat for sled test of seat subsystem in frontal collision,determines the parameters and structures that affect the forward displacement and submergence of the H point of dummy.Through orthogonal test,the importance of each factor to the performance is systematically analyzed.At the same time,a design method is proposed to comprehensively consider the seat anti submergence performance and ride comfort.The balanced design scheme of the seat safety and comfortableness is given..
