Design of Shipborne Reducer Box Damping in Reducing Vibration

Abstract:

The structure noise of marine gear reducer seriously affects the concealment of ships, the stability of transmission system and comfort of crew's working environment. There are many ways to control structural vibrations, in which adding damping structure into reducer box is an effective measure to restrain the resonance. Aiming at the excessive vibration of box 240569 node, this paper realized the design of damping reducing vibration with the method of shell structure damping design finite element. Finally, the authors verified vibration during box reducer normal operation through harmonic response analysis.
