摘　　要：以同向捻钢丝绳为例,研究钢丝绳中一次螺旋线与二次螺旋线的几何周期关系。在均匀性假设下,取钢丝绳中心丝,任一股中心丝,以及股外层丝为研究对象,研究了单根丝的完全周期,分析钢丝绳捻距、股捻距、股在钢丝绳中的捻角关系,指出钢丝绳参数关联因子n取有理数是由钢丝绳结构周期性所决定的。钢丝绳出现周期性的本质是由结构和捻向共同决定的。Taking lang-lay wire rope as an example,the geometric period relationship between primary spiral wire and secondary spiral wire in wire rope is studied.Under the assumption of uniformity,the center wire of wire rope,any center wire of strand,and the outer layer wire are taken as research object.The complete cycle of a single wire is studied,and the relationship between lay length of wire rope,lay length of strand,and lay angle of strand in the wire rope are analyzed.It shows that wire rope parameter correlation factor n is a rational number is determined by periodicity of wire rope structure.The periodicity of wire rope is essentially determined by structure and lay direction.
