Abstract

In this paper, a 3-D finite element model of a gear-rotor-bearing-box coupling system is developed by coupling transmission subsystem and structure subsystem with the support of bearing for the analysis of the kinetic characteristic of large burden marine gearbox. Based on the research on the change of contact line of helical gears, a method of calculating the time-variant stiffness is proposed. Considering the effect of internal and external excitation on the transmission subsystem, its kinetic characteristic is dealt with by numerical simulation. The kinetic evaluating indexes of structure subsystem, such as vibration displacement and velocity, and the structure preestimated noise are obtained. The research results lay down a theoretical basis to optimize the dynamic performance of large burden marine gearbox.
