电梯液压缓冲器复位工况和复位时间分析

简单介绍了电梯用缓冲器的基本类型、结构及工作原理，着重分析了耗能型缓冲器复位过程的力学及运动学特征，给出了判定缓冲器复位时间的理论依据。经过计算分析可知，缓冲器复位时间短暂，为此开发了一种实用性较强的缓冲器复位时间测试仪。

Analysis on the Return Case and the Return Period for Hydraulic Buffer

This paper introduces the type, construction and principle of buffers, analyzes the mechanics and kinematics features of return course of dissipation type buffer and describes the theory of determining the its return period. Based on the calculation, we know that the buffer return period is very short, and a practical buffer return period test instrument has been developed here.
