Abstract EN
A simple yet accurate solution procedure based on the improved Fourier series method (IFSM) is applied to the vibration characteristics analysis of a cylindrical shell-circular plate (S-P) coupled structure subjected to various boundary conditions.
By applying four types of coupling springs with arbitrary stiffness at the junction of the coupled structure, the mechanical coupling effects are completely considered.
Each of the plate and shell displacement functions is expressed as the superposition of a two-dimensional Fourier series and several supplementary functions.
The unknown series-expansion coefficients are treated as the generalized coordinates and determined using the familiar Rayleigh-Ritz procedure.
Using the IFSM, a unified solution for the S-P coupled structure with symmetrical and asymmetrical boundary conditions can be derived directly without the need to change either the equations of motion or the expressions of the displacements.
This solution can be verified by comparing the current results with those calculated by the finite-element method (FEM).
The effects of several significant factors, including the restraint stiffness, the coupling stiffness, and the situation of coupling, are presented.
The forced vibration behaviors of the S-P coupled structure are also illustrated.
