- 摘要：
- The vibroacoustic coupling between a 'nite circular cylindrical shell closed at each end by
a piece of circular plate and its enclosed cavity is analyzed in this paper by using a new
method, called the covering-domain method. The covering-domain method, which
transforms the calculation of the scattering sound 'eld of a complicated-shaped close cavity
to that of a series of simply regular-shaped close shells such as close spherical shell and
in'nite cylindrical shell, is applied to calculating the scattering sound 'eld of the plate-ended
cylindrical shell structure. So we can predict radiated sound pressure of the composite elastic
structure excited by an external force by using the acoustical reciprocity theorem. The new
method expands practical application of the reciprocity theorem. It is veri'ed to be valid by
a corresponding test.
