摘要
电梯在紧急情况下,制动器、安全钳、缓冲器3种不同的安全保护装置分别参与电梯的紧急制动,可能导致轿厢内人员受到伤害,然而这种受伤害程度无法定量测量。文中针对不同工况下,轿厢内人员采用不同姿势,当电梯紧急制动时,轿厢内的人员将受到多大冲击载荷,以及以超出缓冲器允许的速度撞击缓冲器时,轿厢内人员将受到多大伤害,利用假人进行实验比对研究,并获得结果。
In case of emergency,if three different safety protection devices,including the brake,safety gear and buffer,are used for emergency braking of elevator at the same time,people in the car may be injured,but the degree of injury cannot be measured quantitatively.For problems such as under different working conditions and different postures,how much impact load will people in the car be subjected to during emergency braking,and how much harm will be caused when the speed exceeds the allowed value by the buffer,the dummy is used for experimental comparison and research,and results are obtained.
