Abstract
A coupled vibration model of a stiffened cylindrical shell with a stiffened interior plate is established based on the receptance method to get the stiffeners' influence on the plate-shell coupled structure's vibration characteristics. Numerical analysis on how an increase of the plate's and the shell's stiffener number affect the combination's vibration is carried out. It shows that the amplitudes of both the plate's and the shell's acceleration levels would reduce and peaks of their vibration curves would shift to the higher frequency range as stiffeners on the plate increases. And increase of the shell's stiffener number has little impact on the plate's acceleration level curve except for some peaks, but it would reduce the shell's acceleration level.
