Method for testing aluminum honeycomb panel

The invention relates to an aluminum honeycomb panel testing method, which comprises the following steps of: connecting an aluminum honeycomb panel on an electric vibration exciter, and capturing the displacement of the aluminum honeycomb panel by using two high-speed synchronous cameras; exciting the aluminum honeycomb panel by using a micro accelerometer and capturing response, and identifying the inherent frequency by using a peak taking method; in DIC measurement, a vibration exciter excites the aluminum honeycomb panel with sinusoidal vibration tuned to inherent frequency, so that the aluminum honeycomb panel resonates and vibrates, and a modal shape is identified; exporting the collected displacement data to calculate a working modal shape; and judging whether the aluminum honeycomb panel is damaged or not according to the inherent frequency. In the aspect of damage detection, the method uses curvature change to position damage, identifies a damaged area by constructing a damage index graph, filters abn
