Description
Summary:碩士 === 國立海洋大學 === 造船工程學系 === 82 === The problem of vibration and noise is always the major concern in naval architecture. The present study addresses to develop a general, automated, procedure for prediction and analysis of ship's vibration and noise . Finite Element Method (FEM) is applied to describe the vibrations of ship, and boundary elements method is employed to deal with the acoustic behavior. There are two cases will be presented in this paper. In order to show the procedure of dealing with the elastic - water coupled problem, the first one is a elastic ellipsoidal submerged model. The second case is a real situation of ship's vibration and noise of which approximation of acoustic boundary is introduced inorder to meet the computational capacity for engineering practice.
