摘要
本文利用ProE/5.0建立2/3捻距钢绳环非连续接触三维模型,在Abaqus中进行轴向拉伸和扭转载荷下的非连续接触钢绳环有限元分析,在非连续接触钢绳环损伤试验台上对钢丝绳进行磨损实验,并借助光学显微镜(OM)对磨损后钢丝表面磨痕分布进行了分析,结果表明:等效应力、轴向应力、轴向变形均沿钢丝绳轴线方向呈螺旋状分布,在绳股截面上,等效应力由芯丝向侧丝逐渐递增,在绳槽接触区域出现最大值,实验表明钢丝表面也呈现椭圆磨痕,与仿真结果相一致。
In this paper, the 3-D model of discontinuous contact of 2/3 lay length steel rope is established by ProE/5.0. Finite element analysis of discontinuous contact steel rope under axial tension and torsion load was carried out in ABAQUS. The wear test of wire rope was carried out on the discontinuous contact steel wire rope damage test bench, and the distribution of wear marks on the worn steel wire surface was analyzed by optical microscope(OM). The results show that the equivalent stress, axial stress and axial deformation are spiral distribution along the axial direction of the wire rope;on the strand section, the equivalent stress increases gradually from the core wire to the side wire, the maximum value appears in the contact area of rope groove, the experimental results show that the steel wire surface also presents elliptical wear scar, which is consistent with the simulation results.
