双驱动卷场杨是在行星减速器基础上发展起来的节能、环保型新一代扬机。简述了卷扬机多流动传统的基本原理，采用键僵图理论和方法，建立卷扬机多流传动系统耦合振动健合图模型，推导出传动系统的状态方程，并进行了系统动力学的仿真分析，获得了系统内部各部分状态变量的变化规律及关系，较全面地揭示了系统的传动性能及动态特性。研究结果为进一步深入研究卷扬机多流传动系统提供了动力学分析方法和设计依据。

The double drive hoist reducer developed in the planetary gear is a new generation of energy saving and environment protecting hoist product. The multi flow transmission system theory of hoist is analyzed. With the theory and method of bond graph,a bond graph model with coupled vibration is established for hoist multi flow transmission system for the first time. The state equation of the system is developed and dynamic simulation analysis is also carried out. The internal changing law and relationship of the system for the state variable are got. Therefore, the dynamic properties and gearing features of this system are revealed comprehensively. The research results can provide the dynamic analysis method and design basis for multi flow transmission system of hoist.
