Verification of Vibration Isolation Effectiveness of the Underwater Vehicle Power Plant

In order to enhance the vibration isolation effectiveness of an underwater vehicle power plant, and alleviate mechanical outer housing, initially discrete isolators were improved, three new types ring designed, i.e., metal rubber isolators, magnesium alloy modified ultra-high polyethylene (MUHP). A vibrator excitation test was carried out, evaluated, adopting insertion loss energy level drop. The results showed that compared with initial other two MUHP most significant effectiveness. Furthermore, its verified by a plant. To improve effectiveness, in addition it is essential carry out investigations on high-impedance housings.
