Abstract:In this paper an equivalent method based on sandwich plate theory is deduced and the equivalent pa鄄
rameters of the honeycomb plate are obtained. With these equivalent parameters, the honeycomb plate FEM simula鄄
tion model is established and honeycomb sandwich plate static analysis and random vibration analysis are completed.
Then static and random vibration tests were made. The results indicated that the honeycomb sandwich plate theory
based model can accurately reflect the honeycomb sandwich plate static strength characteristics and structural dynamic
characteristics. Static strain value and the error is less than 4%, the natural vibration frequency and the error is less
than 5%, which shows good agreement with tests results and the effectiveness of the model.
