[Objectives]As the first element to support the shaft and transfer the vibration, water-lubricated stern bearing becomes an important part of ship shafting. To enhance its dynamic performance on vibration and noise reduction,[Methods]a fluid-saturated perforated slab was designed. Based on the theory of fluid-structure interaction,the modal analysis and harmonic response analysis on conventional water-lubricated stern bearings and the water-lubricated stern bearings with fluid-saturated perforated slab were carried out by using the finite element analysis software ANSYS to analyze the influence of the fluid-saturated perforated slab.[Results]The simulation and test results show that the design of the fluid-saturated perforated slab can effectively reduce the vibration amplitude of stern bearing.[Conclusions]The research results has certain guiding significance for the improvement of the performance of stern bearing. |
