摘要:

交通事故中汽车重量对人体伤害的影响取决于事故工况。很多严重事故只涉及一辆车,则自车的动能是唯一的"杀伤力"。从交通伤害防控整体考虑,汽车轻量化对降低交通事故伤害利大于弊。

关键词: 交通安全, 事故伤害, 汽车重量, 冲击力学

Abstract:

In vehicle collision accidents, the influence of the vehicle mass on the human body injuries depends on the accident conditions. Many severe accidents involve only one car, and the car's kinetic energy is the only "power" for producing injuries. From a viewpoint of the injury prevention for the entire road traffic, the lightweight of the vehicle has more positive effect than the harmful one.

Key words: traffic safety, accidental injury, vehicle mass, impact mechanics
