This paper presents an analysis of the vibration characteristics of a conical shell with a fixed support. Firstly, a reasonable numerical calculation model has been established based on the Donnell shell theory, and the first 9 modes has been calculated by Numerical method with MATLAB. Then, the finite element model of conical shell has been built on the ANSYS Workbench simulation platform. With specific constraints set, modal analysis has been carried out on the model of conical shell to find and verify the corresponding numerical model is convergent.
