| Abstract: | Fluid filled pipe systems are widely used in ship industry,such as cooling,water conveying systems,etc.Its vibration and underwater acoustic radiation has always been a hotspot in academic research and engineering application.The continuous boundary conditions of the force and displacement at the coupling point were cosidered,and the analytical study of the liquid filled pipeline,the finite element calculation of the hull and the test of the pipeline support were combinedly used based on the impedance synthesis method to investigate the vibration characteristics and underwater acoustic radiation of the pipe-hull coupled system.The synthesis method was applied to a complex spatial pipeline-hull coupling model,and the results were compared with the finite element results to verify the correctness of the method proposed. |
