起重机钢丝绳剩余破断拉力的试验研究

Experimental Research on Residual Fracture Tension of Wire Ropes on Crane

钢丝绳剩余破断拉力与钢丝绳驱动卷绕系统的失效概率有着密切的关系,因而它的大小直接影响到冗余并联的钢丝绳驱动系统的可靠性。本文介绍了钢丝绳剩余破断拉力的试验研究方法、试验方案、数据处理和回归分析等。

Residual fracture tension of wire rope is closely related to failure probability of hoisting system of wire rope.Therefore,its quantities affect directly the reliability of redundant parallel hoisting system of wire rope.This paper introduces the experimental scheme and research method,data processing and re- gression analysis on residual fracture tension of wire rope.
