Abstract
Abstract
In this paper, the finite element model of marine gearbox is established, using Lanczos method performed the modal analysis of the gearbox system mathematical, the modal frequencies and modal shapes of each order of the box were obtained, and the modal experiment of marine gearbox is carried out. The results show that by comparing the data obtained from the experimental modal analysis with the theoretical calculated values, it is verified that the theoretical analysis values and experimental test values are in better agreement, and the maximum frequency error is 4.04%, the fea model is reliable, thus theoretical model could better reflect the natural vibration characteristics of the box on the marine gear box.
