1×7+IWS结构钢丝绳有限元分析

The Finite Element Simulation for 1 × 7 + IWS Steel Wire Ropes Based on UG and ANSYS

为提高钢丝绳的安全性,最大限度发挥材料性能,合理地设计和制造满足各种性能要求的钢丝绳产品,采用UG软件对1×7+IWS结构的圆股钢丝绳进行三维实体建模,然后通过UG与ANSYS的接口导入ANSYS中。采用面—面接触求解方法,对导入的钢丝绳实体进行有限元网格划分、建立接触对和施加约束并求解。研究了捻距S对服役中的钢丝绳应力应变的影响,得到相应的应力应变云图,为钢丝绳的设计和改进提供了理论依据。

In order to improve safety of steel wire ropes, make full use of the material performance and reasonably design and manufacture steel wire products satisfying various performance requirements, the 3D solid model of 1 ×7＋IWS circular strand steel wire rope was established by using UG, and imported into ANSYS through the in-terface of UG and ANSYS.The solid model was divided into finite element mesh, and contact pairs were estab-lished, restraint applied and solved by the surface-surface contact analysis method in ANSYS.Influence of lay length S on the stress and strain in steel wire rope in service was studied, and the corresponding stress-strain contours were obtained, which provides theoretical basis for design and improvement of steel wire ropes.
