An analytical estimation method is described for the shell mode vibration of piping coupled with the pulsation of contained fluid. The object of the analysis is restricted to the N=0 (N denotes circumferential wave number) mode of shell vibration. The contained fluid is considered as an axisymmetric viscous flow, and continuity at pipe wall is defined as the coupling condition between the pipe wall vibration and fluid pulsation. The response of a coupled system is formulated in the frequency domain by means of the transfer matrix method. The estimated responses of pressure pulsation and piping vibration are compared with measured responses in a model piping system having a simple configuration, and it is found that the estimated frequency frequency response and mode shapes agree well with the measured data.
