. The type and working principle of multi-engine multi-gearboxgearing are introduced. The global dynamic modeling method, based on thegeneralized finite element theory, and the layered dynamic modeling method,based on the idea of whole first and then partial are proposed, and thedynamic models of three operation modes in the four engines with two shafts are established. The effects of coupling, rotation speed, configuration andpower loss on the dynamic response of the system are studied by using thedynamic model. The research results show that the coupling vibration ofmulti-engine multi-gearbox gearing is obvious at low speed, and the coupling vibration weakens with the increase in speed. Reducing the coupling stiffness can weaken the coupling vibration of the system. The symmetrical structure of the transmission system has the same dynamic response at the symmetrical position. Meshing friction has little effect on the dynamic response of the system. The more power flowing through the cross-connect gearbox, the greater the system power loss. This research provides theoretical support for the low-vibration design of multi-enginemulti-gearbox marine gearing and has a positive significance for understanding the coupled vibration characteristics of complex gear systems.
