| Abstract: | Based on elastic wave theory and bending vibration equation of plate, the vibrational characteristics of thin annular plates is analyzed. The extensional and bending vibration of the thin plate is addressed respectively. A new method for calculating the dynamic reverse forces is given. These forces are introduced as displacement dependent load, whose magnitudes reflect the elastic and inertial properties of the plate. An example dealing with this calculation is offered. |
