Abstract

Two control approaches are presented in this paper for the vibration control of ship structures. One aims to control vibration energy transmission from vibrating machinery to a ship structure by modifying the input mobility of the local supporting structure. Another aims to control vibration energy propagation in the ship structure by introducing irregularities to the ring frame locations. Four structural modifications are proposed in the first approach. The effect of the modifications to the force and moment input mobility at the engine mount locations is discussed. It is found that vibration energy transmission from a mechanical source to the ship structure can be controlled by structural modifications of the local supporting structure. In the second approach, we found that vibration of the ship structure at low frequencies can be confined at the source section by moving some of the ring frames away from their respective periodic locations

Impact and interest:

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
