摘要：
Model of the cylindrical shell with internal substructure system was decoupled by the condensed transfer function. The dynamic behavior of cylindrical shell and the internal substructure model were obtained by the direct stiffness method respectively. Then the vibration response of the complex structure was solved by the condensed transfer function (CTF) method. The coordinate transformation matrix and the coupling in six directions were employed to ensure the calculation accuracy of the CTF method. The effectiveness of the CTF method was verified by comparing the calculation results with the finite element results. The influence of structural thickness, shell length, boundary condition and excitation direction on the vibration characteristics of cylindrical shells with internal substructures was analyzed based on research above. © 2022, Editorial Board of Journal of Huazhong University of Science and Technology.
