Performance Analysis of the Floating Raft System Base on the MSC.Patran

Pro/Engineer and MSC.Patran were associated to establish the finite element model for the floating raft system.The frequency response analysis of the floating raft system was carried out in MSC.Nastran.The effect of vibration isolation was investigated by the power average method,as well as the influence of main structure parameters upon the isolation effect of the floating raft system.
