Numerical Simulation on Shock Isolation Characteristics of Ship Equipment

In this paper, the marine supercharged boiler was researched by time-domain simulation method. With the condition of underwater explosion, the dynamic responses of marine supercharged boilers with and without impact damper were simulated and studied respectively. Then the effect of impact damper on shock resistance was studied and some rules are obtained. The resuhs show that the boiler＇s anti-shock performance is enhanced by the e shock isolation installation. The research aims to provide some references to the design and evaluation of ship equipment shock-resistance performance.
