A typical marine shafting test bench was investigated in this paper. A finite element model of the shafting was established based on FEM and verified by tests. Natural characteristics of the shafting with main engine vibration isolation were analyzed. Lateral rolling was predigested as equivalent variational acceleration of gravity. It was applied to FEM model for the transient response analysis as boundary conditions. The computation results indicate that main engine vibration isolation reduce the natural frequencies of the whole system but makes no difference to those of shafting. Transfer forces and displacements at coupling increased and transmitted to shafting, causing much stronger vibration of shafting.
