A receptance synthesis approach was formulated to investigate the dynamic characteristics of a coupled beam-cylindrical shell system. The system was divided into a beam substructure and a shell substructure. The receptance functions for the beam and cylindrical shell substructures were determined using the improved Fourier series method and the wave propagation approach respectively. Based on the kinematic compatibility and force equilibrium conditions at the coupling interfaces of the substructures, the responses of the coupled system were directly predicted though the load applied to the substructures. The receptance synthesis approach was then used to determine the responses of a beam-shell system which serves to validate the correctness of the method, comparing with a FEA model. The vibration responses of a coupled lumped mass-shaft-cylindrical shell system were then used to study the effects of modifying some model parameters.
