Abstract: In order to solve the forced vibration response of rotating short thin walled cylindrical shells, an innovative calculation method is proposed considering the different boundary conditions in the axial displacement functions based on beam functions. The method is on the basis of the research results proposed by researchers previously. They studied the calculation method of the free vibration and harmonic excitation response of rotating finite cylindrical shells under the one condition of simply - simply supported boundary only. The vibration differential equations for rotating cylindrical shells were established using the Hamilton principle based on the Love’s shell theory. The differential equations are transformed to ordinary differential equations by using Galerkin’s method. Taking an example of the simple harmonic excitation, the calculation method of the forced vibration response of rotating short cylindrical shells under the different boundary conditions is given. The proposed calculation method is verified by experiment.
