| Abstract: | Objectives Compared with 1-stage, 2-stage and raft vibration isolation, the attenuation of longitudinal wave and bending wave transfer for blocking mass is low, and relatively few scholars are interested in studying the application of these measures. However, with the development of submarine noise and vibration reduction, designers should survey such less effective measures as blocking mass. Methods In this paper, the attenuation characteristics of blocking mass in a simple system are analyzed via the Wave Propagation Approach(WPA). Combined with engineering practices, a |
