Abstract

Abstract

The governing equation and energy equations for thermal-elastic coupling vibration of cylindrical shell were developed.The Garlerkin method was used in numerical process.Some useful result can be concluded from numerical result.With the increase of the amplitude of temperature and coupling coefficient,the speed of vibration decaying becomes slower and the coupling effect becomes weaker.The larger the ration of length to radius and length to thickness,the faster the decaying of the vibration amplitude and the vibration frequency increase.It means the coupling effect gets stronger.The larger the coupling coefficient,the smaller the axial stress,the axial force and the bendind moment are.
