Vibration Characteristics Analysis and Experiment of Marine Gearbox’s Finite Element

The analysis of vibrationexciting forces for a marine gearbox, the model establishments of a multi-stage gear transmission and the marine gearbox and the vibration characteristics calculation of the gearbox body surface are proved in the paper. The models and the calculation method are verified by the vibration experiment. The finite element analysis is an effective method for the vibration characteristics of the marine gearbox.
