Abstract
In this paper, the experimental and Jacobi–Ritz method (JRM) have been adopted to analyze the forced vibration analysis of uniform and stepped circular cylindrical shells with general boundary conditions. The simply supported cylindrical shell at both ends is taken as an experimental model, and the free, steady and transient vibration characteristics of structures under hammer and fixed exciter are recorded. The results show that the results of JRM are in sensible agreement with those in experiment. In addition, the results for various boundary conditions, structural parameter are also presented. On this basis, the Newmark-[Formula: see text] integration method is adopted to realize the time domain solutions for transient vibration response, and the frequency domain results can be obtained by using Fourier transformations from time domain results. Finally, the line spectrum vibration response results of the structure are presented under the random excitation load, and the research can supply technical support for the vibration control of cylindrical shell structure.
