Abstract:The vibration of propeller exciting force transmitted to the hull through the shafting is an important aspect that affects the acoustic performance of the stern. To achieve the purpose of attenuating the vibration magnitude of the transmission path, particle damper is arranged in the shaft section between propeller and thrust bearing. The energy consumption results of propulsion shafting with different damper schemes are obtained through simulation, and the influence of damper configuration on the propulsion shaft is analyzed. Then, based on the shafting mechanism test bench, taking the vibration acceleration response magnitude of thrust bearing base as the evaluation index, the applicability and actual effect of particle damping damper in vibration reduction of propulsion shafting are fully evaluated. The experimental results show that the particle damper installed in the appropriate position can obtain better damping effect, and verify the accuracy of the simulation results.
