  • Characteristics of vibration in middle-high frequency for a ring stiffened shell by vibration measurement are predicted in this paper. In middle-high frequency, the transfer function of vibration energy from the measured points to all subsystems is deduced by the Statistical Energy Analysis. Further more, mean square velocity of the shell can be obtained. Using the vibration signal of measured points as inputs, the mean square velocity of the shell is got by the transfer function of deduced vibration energy in numerical calculation. The result shows that the prediction method in this paper is feasible and more accurate in comparison with predicted values of calculation with experimental values.
