摘　　要：基于钢丝绳的空间螺旋结构及微分几何理论,利用三维建模软件和有限元法建立1×37 IWS单捻钢丝绳三维实体模型和有限元模型,采用Augmented-Lagrangian算法及相应接触参数,结合相应的边界条件进行仿真。仿真显示:在轴向载荷作用下,中心丝的应力要大于其他层钢丝应力;由于钢丝绳股内钢丝点接触状态,导致钢丝应力呈现等幅度周期性波动;理论计算和模拟仿真结果基本一致,验证了模型具有一定的合理性。Based on space spiral structure of the wire rope and theory of differential geometry, 3D solid model and finite element model of 1 × 37 IWS single twisted wire rope was established by 3D modeling soiiware and FEM. By using Augrnented-Lagrangian algorithm and corresponding contact parameters, the simulation was conducted with corresponding boundary conditions. Simulation results showed： the stress of the central wire was greater than other layers of wire under the action of axial loads; point contact state of strand wire of the wire rope brought about equal-amplitude cyclical fluctuation of the stress of the wire rope; the theoretical calculation results were generally consistent with the simulation ones, which verified some reasonableness of the model.
