AbstractIn order to improve the numerical calculation accuracy of the hexagonal aluminum honeycomb panel, the influence of the length-thickness ratio on the dynamic calculation accuracy of the equivalent models is studied. The modal frequencies of the equivalent models and the entity model are compared to analyse the influence of the length-thickness ratio on the dynamic calculation accuracy of the equivalent models. The results show that the first 10 order errors of sandwich panel theory model and honeycomb panel theory model are less than 20% for medium thickness panel with length-thickness ratio less than 10.3, so the equivalent effect is ideal. When the ratio of length to thickness of Reissner theory model and honeycomb panel theory model is about 10.3 and 13.7 respectively, the calculation accuracy is low and the error peak appears. The sandwich panel theory model has lower accuracy than other equivalent models for thick panel.
