摘　　要：起重机械中钢丝绳会存在磨损、腐蚀、断丝等损伤现象,致使其在吊装过程中经常发生断裂而引发伤亡事故。本文针对常用的6×19M-WSC单层股钢丝绳结构,考虑钢丝之间的接触行为,利用有限元软件建立钢丝绳仿真实体模型,对比分析单根钢丝、"1+6型"及"1+6+12型"钢丝绳的破断拉力计算值与规范值的大小,总结钢丝绳破断拉力计算规律;并采用断丝模拟钢丝绳的损伤情况,研究钢丝绳的损伤对其破断拉力的影响,进一步为起重机械中钢丝绳的使用提供相应的参考依据。The steel wire rope in hoisting machinery will be damaged by wear,corrosion,broken wire and so on,which often lead to fracture and cause casualties during hoisting process.In this paper,the simulation entity model of 6×19 MWSC with single-layer wire rope structure was established by using finite element software on the basis of considering the contact behavior of steel wire.This paper compared and analyzed the calculated values of breaking tensile force of single steel wire,"1+6 type"and"1+6+12 type"steel wire rope and summarized the calculation law of breaking tension force of wire rope.The damage of wire rope was simulated by wire breakage,and the influence of wire rope damage on its breaking tensile force was studied,which provided a reference for the use of wire rope in hoisting machinery.
