Abstract

Technological developments to reduce underwater noise caused by equipment vibration on ships are essential to improve the operational capability and ensure the survivability of ships. Accordingly, several studies have been carried out to reduce the vibrations generated by mounted equipment. In this study, a finite element model was developed to predict the dynamic characteristics and control effects of a simple simulation test equipment designed to simulate the operating states of a ship. The predicted results were compared with the experimental results obtained from the fabricated test equipment to verify the accuracy of the model. The double elastic support model of the test equipment was designed using shell elements. The vertical and horizontal stiffnesses of the mount were defined using the Bushing Joint component. The dynamic characteristics and vibration reduction effects predicted by the active assembly of the finite element model showed good agreement with those observed from experiments.


Keywords: Structure-borne noise, Vibration reduction, Pasive mount, Finite element analysis, Active assembly
