在拙作“弹簧缓冲器的设计计算”《建筑机械化》1989№1一文中曾指出,要确定弹簧所受最大压力,就牵涉到最大减速度α的取值问题。同样,对安全钳来讲,首要问题是制动力的大小,这也牵涉到减速度α的取值。根据电梯技术条件(JB816-74)规定,不同速度的电梯有不同的制停距离,其减速度也有不同的相应上下限。并且随着电梯速度的增大,制停距离也加大,减速度的上下限也随之变大。至于《电梯制造与安装安全规
In the paper “Design and calculation of spring buffers” in “Construction Mechanization” (1989 No. 1), it was pointed out that to determine the maximum pressure on a spring, the value of the maximum deceleration α is involved. Similarly, for the safety gear, the first issue is the magnitude of the braking force, which also involves the value of the deceleration α. According to elevator technical conditions (JB816-74), elevators with different speeds have different stopping distances, and their decelerations also have different corresponding upper and lower limits. And as the speed of the elevator increases, the stopping distance increases and the upper and lower limits of deceleration also increase. As for elevator manufacturing and installation safety regulations
