Experimental Study on Dynamic Response Characteristics of the Panel in Transonic Regime

An experimental investigation was conducted to characterize the dynamic response of a thin panel in the transonic regime from Mach 0.8 to 1.2. A panel-frame model was designed and tested in the FD-06 wind tunnel. The dynamic characteristics were captured using synchronized multi-physics measurement techniques. The results identify two distinct aeroelastic regimes: a lock-in regime with high-frequency, narrowband vibrations at lower Mach numbers, and a low-frequency and suppressed-vibration regime at higher Mach numbers. This study provides critical experimental data for the structural design of high-speed unmanned aerial vehicles.
