多层卷绕系统中钢绳跳槽力学行为分析

Analysis of groove-jumping behavior in the multilayer winding system

多层卷绕系统中,随着卷绕层数增多,容易出现钢绳排列凌乱、互相交叉挤压导致钢绳磨损。针对双折线绳槽卷筒钢绳卷绕中的跳槽问题,根据钢绳跳槽的行为特点,首先给出了钢绳跳槽段及其包角的定义,在此基础上建立了钢绳跳槽的受力模型,从力学角度分析并得出了卷筒钢绳直径比e、钢绳缠绕层数k、钢绳张力以及钢绳进出卷筒偏角γ与钢绳跳槽行为的关系,并通过ADAMS进行了仿真验证,为多层卷绕系统的设计提供了参考。

In the multilayer winding system,with the increase of the winding layer,the ropes tend to be in disorder,crossing and extruded,leading to wire rope wear.For the Lebus groove wire rope winding system,according to the groove-jumping characteristic,the rope jumping section and wrap angle are defined,with the groove-jumping force model set up;on this basis,from a force point of view,the relationship is analyzed of reel and wire rope diameter ratio e,wire rope winding layers k,and wire rope fleet angleγwith the groove-jumping behavior,and then through the ADAMS a simulation and verification is conducted,providing a reference for the design of multilayer winding system.
