Abstract

Abstract

Based on the dynamic finite element method of structures,the response analysis of a flexible nozzle having a cone cylinder shaped divergent section is presented.The flexible joint is simply treated as a distributed spring and to which the Newmark difference method is applied.The numerical results are obtained when triangular wave excitation,sine wave excitation and arcsine wave excitation are exerted correspondingly.
