摘要
利用相对节点法对钢丝绳建模的方法进行了理论推导,为钢丝绳虚拟样机的建立和分析奠定了基础。然后利用仿真软件RecurDyn对钢丝绳虚拟样机进行了动力学分析,通过钢丝绳长度差和摩擦轮直径偏差对张力不平衡研究分析发现,不同时刻下钢丝绳长度差和直径偏差量对钢丝绳张力影响规律相似,且同等偏差量条件下直径偏差量在张力不平衡中起着主导作用,主要影响了钢丝绳的使用寿命。钢丝绳张力不平衡研究为钢丝绳安全生产提供了一定的参考依据。
In this paper,the relative node method is used to deduce the modeling method of the wire rope,which lays the foundation for the establishment and analysis of the virtual prototype of the wire rope.Then the dynamic analysis of the wire rope virtual prototype is done by using the simulation software RecurDyn,through the research on the influence of the length difference of the wire rope and the diameter deviation of the friction wheel on the tension of the wire rope,the wire rope length and the diameter deviation value under different time of wire rope tension effects are similar,under the same deviation,the diameter deviation of the diameter plays a leading role in the imbalance of the wire rope tension,which mainly affects the service life of the wire rope.The study of the unbalanced tension of the wire rope provides a reference for the safety production of the wire rope.
