摘　　要：为探讨副驾驶员座椅靠背角度对乘员碰撞安全性的影响,建立了某乘用车副驾驶员约束系统模型,采用LS-DYNA软件分析了该车型在正面碰撞时对应于不同座椅靠背角度的副驾驶员损伤情况。结果表明,随着靠背角度的增加,乘员的损伤加重,尤其是头部和颈部损伤。因此,在正面碰撞中,将副驾驶员靠背角度适当调小有利于对副驾驶员保护。For investigating the influence of the backrest angle of co-driver＇s seat on occupant crash safety,a model for the co-driver＇s restraint system of a passenger car is built,and the injuries of co-driver during frontal head-on crash with different seat backrest angles are analyzed by using LS-DYNA software. The results indicate that with the increase of backrest angle,occupant injury,especially his head and neck injuries,becomes more severe.Hence,reasonably reducing the backrest angle of co-driver＇s seat is beneficial for the protection of his safety.
