Vibration Control Research for Four Edges Simply Supported Rectangular Thin Plate

摘要

In this paper, the vibration of power machinery on the deck which is simplified to forced vibration of four edges simply supported rectangular thin plate was studied. The theoretical model of the system is built based on the vibration properties of deck using four-pole parameters method. For analyzing optimal phase relationship among the ship power machines, the deck's kinetic energy is chosen as the objective function. To fulfil active vibration isolation, the phase difference and layout of power machinery on the deck is researched. The analysis result show that this method is simple, reliable and effective to isolate vibration.
