Theoretical Analysis and Experimental Research on the Vibration Characteristics of Typical Vibration Isolation System

Taking the typical miniatures of motor and fan in ship engine room facilities as the power facility objects,this article studies their vibration transfer characteristics from aspects of theory and experiment.Results show that when using the simplified spring and damper vibration isolator to simulate the actual rubber vibration isolator,the vibration isolation effect has certain difference at high frequencies,little effect at low frequency.In order to improve the vibration isolation effect,a damping layer can be pasted in raft body and base,and the vibration isolator stiffness should be reduced and the vibration isolation damper should be selected reasonably.
