摘要
根据微分几何学理论分析钢丝绳股内钢丝的空间位置关系,利用ANSYS软件建立了6×7 IWS钢丝绳的几何模型。通过网格划分得到钢丝变形计算的有限元模型,以钢丝绳一端完全约束,另一端施加轴向力作为加载工况,确立模型求解的边界条件,并进行了钢丝受力变形的数值模拟,得出在此工况下股内各丝的轴向应力、剪应力及轴向变形的分布规律。研究了股内各钢丝受力变形规律,对照分析股内2根钢丝在接触位置各自的伸长量,通过求两丝变形差的方法求得出两丝的错动量。对照分析右同向捻及右交互捻钢丝绳股内钢丝应力及变形结果,研究捻向组合对股内钢丝所受应力及变形的影响,以及捻向组合对股内相接触2根钢丝的错动量的影响,得出了相关结论。
According to the analysis on the space location relationship of the steel wires in the strand of the steel cable with the differential geometric theory,ANSYS software was applied to establish a geometric model of the 6×7IWS steel cable.With the grids divided,the finite element model for the steel wire deformation calculation was achieved.Based on the one end of the steel cable fully restrained and the other end of the steel cable forced with an axial force as the load performance,the boundary condition calc...
