Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The amplitude and radiation efficiency of vibration mode should be considered synchronously for noise control in lower frequency band. To analysis the structural modal radiation efficiency of arbitrary closed structure with arbitrary boundary condition expediently, a numerical method based on BEM is presented. The arithmetic indicates that the contribution to sound radiation of a certain mode can be weakened only by reducing the amplitude of modal response or eliminating the mode in the process of structure-acoustics design, and besides, the calculation of the simple supported and uniformly ring-stiffened circular cylindrical shell shows that the structural modal radiation efficiency are not influenced by the variety in geometry parameters and spacing of the rings with the same material properties, but are increased by increasing the aspect ratio of the length to radius of circular cylindrical shell.
