| Summary: | 碩士 === 國立海洋大學 === 造船工程學系 === 85 === It has great advantages to design a vibro-acoustic
structure by performing a preliminary analysis. The purpose of
the thesis is to perform the dynamics analysis of the large
cavitation tunnel of the National Taiwan Ocean University. The
analysis is performed by using the software package of Finite
Element Methods, ANSYS. The structure is modeled by shell
elements and beam elements and the acoustic medium is using a
3-D acoustic element. The in-vacuo structure's natural vibration
frequencies and natural modes are computed and compared to the
data obtained by the ANSYS analysis using the model provided by
USDDC. A reasonable correction was observed. The consequent
analysis is the natural vibration of the structure-acoustic
coupled system. The natural vibration frequencies under the
acoustic loading were computed which showed lower values than
the natural frequencies without the effect of water.
