Structural vibration optimization of the marine excitation source region based on modal superposition method
2026
Overview
Propeller, as one of the main excitations, causes the vibration of the ship, which seriously affects the life and living comfort of the ship. Therefore, the structure of the marine excitation source region, which acts as a direct action area for the propeller excitation, is essential to the improvement of vibration. Based on the modal superposition method, the modal vibration analysis and vibration transmission law are worked out to conduct a study on the vibration characteristics of the marine excitation source region. The first-order vertical mode shapes of the plate frame model, the plate model, and the lattice model are 35.48 Hz, 42.42 Hz, and 131.42 Hz, respectively. In the vertical direction, the transfer function slightly decreases from the bottom to the 01 deck. In the longitudinal direction, the transfer function visibly decreases from the excitation source to the bow. In the transverse direction, the transfer function significantly decreases from the mid-longitudinal profile to the side shell. An optimization scheme of the marine excitation source region is proposed to reduce vibration response by increasing the number of the bottom longitudinal stiffeners. This paper gives an ideal for optimizing structural vibration, which is of guiding significance for the structural design of ships and the improvement of living comfort.
