The research here was the primary work of the system dynamics behavior study for the wire rope enwinding system in the ZJ70D rig.

本文的研究是对钻机滚筒钢丝绳缠绕系统力学行为研究的探索，旨在对下一步系统结构改进设计提供理论依据。

Based on the differential geometry, mechanical system dynamics, theoretical mechanics, strength of materials and elasticity theory, we made the study for the enwinding system in the roller of the ZJ70D rig. Finally, we solved the equations in the computers.

本文依据微分几何、机械系统动力学、理论力学、材料力学及弹性力学等基础理论，对钢丝绳在LEBUS绳槽滚筒缠绕行为进行了几何、动力学及静力学等方面的研究，并基于ZJ70D钻机结构参数进行求解。

In general, the major results are:(1) Established the geometrical model for the enwinding of the wire rope in the roller, such as the inclination of the wire rope and the climbing equation of roller in the commutation process;(2) Established the tensile force kinetic model for the enwinding wire rope used the Lagrange kinetic equation and the continual kinetic theory in the start up and retard moment. Solved the equations by the method of modal analysis and separation of variables(3) Based on the analysis on the enwinding mechanism of the wire rope, we did the research on the mechanics behavior of the wire ropes enwinding process.(4) According to the research above, we made the computer program to solve the mechanics models. And after parametric analysis, we made the suggestion for the improving of the current wire rope enwinding system.

主要研究工作有：(1)建立了钢丝绳在滚筒缠绕几何模型，研究了钢丝绳缠绕过程极限偏角及换向过程在滚筒爬坡机理及几何模型；(2)依据LAGRANGE系统广义动力学方程、连续体动力学理论分别建立起升系统启动及制动过程钢丝绳缠绕快绳拉力的动力学模型，并分别采用模态分析法及分离变量法求解；(3)结合对钢丝绳在钻机滚筒缠绕机理分析的基础上，研究了钢丝绳在滚筒缠绕过程力学行为；(4)编制计算机仿真程序对上述模型进行求解，在参数分析的基础上提出对目前钢丝绳缠绕系统结构改进建议。
