【Abstract】 The dynamic properties of the complex electromechanical system are significantly influenced by many coupled factors that exist in the system simultaneously. These coupled factors even cause a great failure. Therefore it is necessary to investigate the complex mechanism caused by coupled factors of multiplenetwork in the complex electromechanical system. In this paper, the modeling of globally dynamic model in the complex electromechanical system is discussed, which can prepare for dynamic simulation,mechanism study and global optimization. Meantime, the types and modeling of dynamic equation are analysed in detail. In a modeling example, the globally coupled model is presented to show the interaction between stand vibration system and torsional vibration system of highspeed rolling mill, the relations among all shaft trains of torsional vibration system, the coupled relations among electric control system and stand vibration system, torsional vibration system, the coupled relations among all parts of electric control system, and so on. The dynamic properties and feedback relation of multiple network are clearly given by block diagram.1fig.,12refs.更多还原
