电梯紧急制动减速度的理论分析

Theoretical Analysis of the Emergency Braking Deceleration of Elevator

对欧拉公式适用于钢丝绳与轮槽面发生相对打滑和非打滑工况进行了论证。详细讨论了曳引力，抱闸制动力与紧急制动减速度的关系，给出了电梯在紧急制动工况下减速度的计算式以及计算实例。

This paper argues that the Euler equation is applied to the conditions of relative slip and non-slip between rope and the traction sheave, and analyzes the relationship between the emergency brake deceleration and traction force and braking force. The deceleration calculation formula of elevator in emergency braking condition is given with a calculation example.
