摘　　要：传统的座椅在汽车前碰撞中是不允许产生明显变形的,本文中提出了3种移动式的汽车安全座椅,它们可在汽车前碰撞时发生相应的变形,具有防止乘员下潜,消除安全带与乘员之间的初始间隙和降低胸部加速度的作用;建立了使用3种移动式座椅和传统座椅的汽车前碰撞乘员动力学响应和损伤分析的仿真模型,并进行4种座椅的对比仿真。结果表明,与传统座椅和其它两种移动座椅相比,第一种移动式安全座椅对乘员头部、颈部和胸部具有较好的防护性能。The apparent deformation of traditional seat is not allowed during vehicle frontal impact.In this paper,three types of moving safety seats are proposed,which can deform during frontal impact and hence prevent occupant submarining,eliminate the initial slack of seat belt and reduce occupant chest acceleration.The simulation models for analyzing the kinematic response and injury of occupants sitting in moving safety seats and traditional seat during frontal impact are built and comparative simulations on 4 different seats are performed.The results show that the first type of moving seat can provide better protection to the head,neck and chest of occupants than another two moving seats and traditional seat do.
