Research on the Influence of Hollowness on the Dynamic Characteristics of Marine Shaft System

In order to study the influence of hollowness of marine shaft system change on the vibration characteristics of shafting alignment, this paper takes the shafting of a test bench as the object, combines the finite element method and co-simulation, and takes the hollowness of the stern shaft as the independent variable to complete the static shafting. Mechanics and dynamics calculations, and further analysis of the inherent properties and dynamics of the marine shaft system with hollowness, the research results can provide new theoretical support for the selection of shaft diameter and marine shaft system design optimization.
