基于间隙理念的钢丝绳产品结构参数求解方法

A Clearance-Based Method of Designing and Solving Structural Parameters of Steel Wire Rope

基于钢丝绳间隙设计理念提出一种用于钢丝绳结构设计参数求解的新方法.在设计阶段考虑构成钢丝绳的股与钢丝的捻制变形以及钢丝绳结构与加工工艺等多种约束,采用渐进逼近的方式对捻距倍数、间隙要求、结构参数等多项指标进行优化计算,克服了传统设计方法中进行参数设计时不考虑生产工艺约束,造成设计与生产脱节的缺点.通过一种复合钢丝绳产品的设计案例,表明了该设计方法的有效性,计算出的设计参数与实际生产情况相吻合,能够有效指导生产实践.

A clearance-based method of designing and solving structural parameters of steel wire rope was proposed. Considering twisting direction of strands and wires, producing technique and structure of rope in design process, an approach of stepwise nearness was adopted to optimize the lay of wires, clearances between wires and strands and other structural parameters. The proposed method avoids disadvantage of traditional design method that does not consider the producing technique constraints and, as a result, the design may not accord with practice. An actual design example of a complicated steel wire rope was presented to illustrate the effectiveness of proposed method, and design results accord with practice and can guide production effectively.
