摘　　要：利用Patran软件设计了1×6钢丝绳直线段股和独立绳芯钢丝绳的有限元模型,利用Nastran进行了有限元分析,计算中考虑了一端固定、一端轴向旋转情况下钢丝绳的载荷与应变的关系和股内各钢丝分载荷情况.对比有限元分析结果、理论计算结果和实验结果发现,三者间误差均在容许范围内,验证了本文有限元模型的有效性.With the aid of the Patran software, a new finite model is established for the 1＆#215;6 straight strand and the IWRC straight wire rope and a finite element analysis and calculation is made using the Nastran. The calculation takes into account the variation of axial load with axial strain and load distribution in the situation where one end of the wire is fixed. Comparative finite element analysis result, theoretical calculation result and experimental result show that the errors in the three results are within the allowable range and verify the effectiveness of the finite element model.
