安全气囊是装在轿车上的被动安全装置。当汽车车速在40km/h以上时.若与正面物体发生猛烈碰撞。车上的传感器即时接到车辆的碰撞信号.电脑立即指令将安装在乘员前方隐蔽处的气囊快速充满气体并打开.使其在乘员前方形成一个较大体积的气包。以保护乘员不受伤害.这一整套动作说着似乎较为复杂.而电脑和安全气囊系统却要在0.3s以内完成。安全气囊能否正常工作.事关人身安全。 相似文献

汽车安全带用于在汽车碰撞、倾翻事故中约束乘员,防止其被甩出车外,避免或减轻乘员与方向盘、仪表板、挡风玻璃等车内物品相撞(即二次碰撞),从而起到保护乘员的作用。作为汽车被动安全性的一种措施,安全带已被40多个国家用法律的形式强制使用。 相似文献

《Vehicle System Dynamics: International Journal of Vehicle Mechanics and Mobility》2012,50(3):113-122
SUMMARY The idea of a passive safety belt operated solely by the motor car's door has been rigorously analysed on a mathematical model. By calculation methods, an optimal configuration of the device was produced and a working model built, based on the analytically obtained design specifications. The model proved the feasibility and advantages of the proposed system, which is based on the conventional 3-point safety-belt design and utilises existing car structures. 相似文献
