Research of Hard Elastic Isolation Technology of Marine Gearboxes
2013
Ship gearbox is the important equipment in the mid-high speed diesel propeller system.As the diesel vibration isolation performance promoting,the vibration source from gearbox has become the main factor influencing the ship’s sound performance.The vibration isolation technology of gearbox is crying for break-through,and the vibration isolation measures of the gearbox corresponding to the diesel engine’s are necessary.Taking a twin-engine parallel operation propeller system along with the gearbox as a vibration isolation research object,the hard elastic vibration isolators were designed for gearbox’s vibration control.The modal was analyzed for the vibration isolator set by FEM.And the expectant vibration isolation effect was verified by the test.
