@@@@A power flow testing approach is presented for ring-stiffened cylindrical shell in this paper. According to Flugge cylindrical shell theory, the power flow testing equations are derived to obtain the power flow information from the acceleration and strain signal. In order to verify the presented approach, the finite element model of the ring-stiffened cylindrical shell is excited by axial and lateral force, and the computed acceleration and strain signal is used to obtain the power flow by the presented approach, which is consistent to the computed result by the definition of power flow.
