摘　　要：采用8结点六面体单元,在考虑钢丝间挤压条件下,用SAP84有限元软件计算分析了受轴向拉伸的钢丝绳中钢丝的弹性应力分布,给出了钢丝绳横截面上各钢丝的应力分布和钢丝绳的极限承载力,并对计算结果的误差进行了分析,计算结果可为钢丝绳的结构设计和应用提供依据.In this paper, elastic stress of steel wires under tension was analyzed with finite element method SAP84 in hexahedral elements with 8 nodes in the case of extrusion effect between steel wires. The stress distribution of each steel wire on cross section of rope and the ultimate load of rope were presented. Finally, an error analyse was proceeded for the numerical result, which is provided as reference for the application and construction design of steel wire ropes.
