摘　　要：以罐道绳为研究对象,建立罐道钢丝绳系统动力学模型,得到考虑罐道绳张紧力和自身质量的偏微分方程。对罐道钢丝绳系统模型在罐道绳不同张紧力、提升容器不同提升高度等情况下进行数值仿真分析,仿真结果表明:罐道绳动刚度不受提升容器作用力幅值影响;罐道绳动刚度变化幅值和罐道绳张紧力成正比例关系;罐道绳提升两端处动刚度变化幅值大于提升中间段动刚度变化幅值。Taking cage guide for research objects to build dynamic model of cage guide, and obtaining its dynamic stiffness calculation formulas. Numerical simulation analysis of rope system under different conditions, such as different force of container, different tension of tank rope and different height of lifting container. Research suggests that dynamic stiffness of wire rope hadn＇t been affected by amplitude of force. Dynamic stiffness amplitude of wire rope is proportional to the pretension of wire rope and at the ends of the dynamic stiffness amplitude greater than the middle section of cage guide.
