提高飞机座椅的保护作用研究

A Study on Improving the Protection of Aircraft Chairs

飞机重大事故一般是在前进运动中发生的,有很大的危险性,如何减少对人体的伤害,就成为普遍关注的难点问题.本文研究了飞机座椅的安装方向,根据运动学冲力的概念计算了保险带与座椅的保护作用,提出了一个估算保护作用的公式,计算结果表明,如果把飞机的座椅朝后安装,可以提高对人体的保护效果30倍以上,减少事故对人身的伤害,以此来加强主动防止事故的能力,提高人体的生存能力.

Most aviation accidents occur in the forward movement with much danger, and how to reduce the harm to the human body becomes a conventionally concerned and a difficult problem. The orientation of the vehicle chairs is studied in this paper by comparison. The protection of the belt and the chair is calculated according the impulsive force. An estimate formula of the chair protection is presented in this paper. The result shows that if the aircraft chair is set to backwards, the total protection to the passenger will be thirty times higher. The effect will make the survival ability higher.
