| 摘 要： | Based on wave theory, blocking mass impeding propagation of flexural waves was analyzed with force excitation applied on a ship pedestal. The analysis model of a complex structure was developed by combining statistical energy analysis and the finite element method. Based on the hybrid FE-SEA method, the vibro-acoustic response of a complex structure was solved. Then, the sound radiation of a cylindrical shell model influenced by blocking mass was calculated in mid/high frequency. The result shows that blocking mass has an obvious effect on impeding propagation. The study provides a theoretical and experimental basis for application of the blocking mass to structure-borne sound propagation control.

| Abstract: | Based on wave theory, blocking mass impeding propagation of flexural waves was analyzed with force excitation applied on a
ship pedestal. The analysis model of a complex structure was developed by combining statistical energy analysis and the finite
element method. Based on the hybrid FE-SEA method, the vibro-acoustic response of a complex structure was solved. Then, the
sound radiation of a cylindrical shell model influenced by blocking mass was calculated in mid/high frequency. The result
shows that blocking mass has an obvious effect on impeding propagation. The study provides a theoretical and experimental
basis for application of the blocking mass to structure-borne sound propagation control. |
