Abstract

The anti-vibration cave is an effective measure for vibration reduction at ship stern. Based on theories of vibration and plate structure, an approximate calculation method of natural frequency of rubber plate was deduced and verified. The influence of design parameters on the fundamental frequency was summarized. A two degree-of-freedom (DOF) vibration system was then established to analyze vibration reduction effect of the anti-vibration cave, and factors to be considered during design phase were discussed. Finally, an anti-vibration cave was designed on a 318,000 DWT VLCC to verify its effectiveness. This paper gives detailed analysis on frequency characteristics and design parameters selection of the anti-vibration cave, which provides practical reference for ship vibration reduction.

Key words
