Abstract： A novel scheme for panel flutter suppression is proposed by the authors of this article. In this scheme the panel is designed as a sandwich panel incorporated with distributed micro beam-type dynamic absorbers acting as its core layer. To improve this scheme, the frequency design method for the dynamic absorber is investigated in the present study. Based on the mode-coupling mechanism of panel flutter, the frequency design of dynamic absorber is performed according to the single-frequency design scheme and double-frequency design scheme respectively. Numerical simulation results show that when all the micro dynamic absorbers are designed with single-frequency design scheme, a maximum flutter speed for the sandwich panel can be achieved at the optimal absorber frequency, which is different from the flutter frequency or the natural mode frequencies of the original sandwich panel; and when the micro dynamic absorbers are designed with double-frequency design scheme, a maximum flutter speed of the sandwich panel which is much bigger than that obtained by single-frequency design scheme can be achieved.
