摘要：
In this paper, the dynamic stiffness method is adopted to analyse the vibrational characteristics of plate structures, considering both in-plane and out-of-plane waves. Through the use of dynamic stiffness method, the displacement contour and frequency response of the L-shaped plate under uniform excitation are studied. This method is validated through comparing the results from DSM and those from FEM. Then, taking a double bottom tank as an example, the vibrational response and power flows are analyzed by dynamic stiffness power flow approach. The results show that dynamic power flow approach can clearly display the power flow information within complex structures and can easily give the dynamic stiffness matrix of complex structures, which is helpful to study the dynamic mechanism, vibration transmission and waveform conversion of complex plate structures. © 2019, Editorial Board of Journal of Ship Mechanics.
