Study on design method and vibration reduction characteristic of floating raft with periodic structure
The noise level is getting higher with the development of high-power marine power plant.Mechanical noise is one of the most obvious noise sources which not only affect equipment reliability,riding comfort and working environment,but also enlarge underwater noise.The periodic truss type device which is commonly applied in fields of aerospace and architectural is introduced to floating raft construction in ship.Four different raft frame structure are designed in the paper.The vibration transmissibility is taken as an evaluation index to measure vibration isolation effect.A design scheme with the best vibration isolation effect is found by numerical method.Plate type and the optimized periodic truss type raft frame structure are processed to experimental verify vibration isolation effect of the structure of the periodic raft.The experimental results demonstrate that the same quality of the periodic truss floating raft has better isolation effect than that of the plate type floating raft.
