摘要
主要介绍了圆股钢丝绳几何建模与力学分析的理论研究进展。在总结描述钢丝绳几何与运动学参数的基础上,结合Love-Kirchhoff曲杆理论、赫兹理论、Winkler地基模型和Archard-Kragelsky磨损定律,分析了在拉压、剪切、弯曲、扭转和局部接触等载荷作用下钢丝绳螺旋分层结构的非线性力学现象,并将钢丝绳的几何建模、运动描述、整体变形、接触应力与磨损之间的关系加以综合考虑,加深对钢丝绳结构和相关力学分析的理解,为进一步研究此类问题拓宽思路。
Progress in theoretical study on geometric modeling and mechanical analysis of the columnar-strand wire rope was introduced in detail. After summarizing of geometric and dynamic parameters of the wire rope, in combination with Love-Kirchhoff theory of curved rods, Hertz theory, Winkler foundation model and ArchardKragelsky abrasion law, the paper analyzed nonlinear mechanical behavior of spiral delamination of the wire rope under the action of squeezing, shearing, bending, torsion and local contact. Moreover, the relationship among geometric modeling, kinematic expression, total elastic deformation, contact stress and abrasion were taken into comprehensive account, thus the understanding of wire rope structure and relative mechanical analysis was enhanced, so as to broaden the thinking of studying this kind of problem.
