Abstract:The intrinsiccharacteristicsof al-composite honeycombcore sandwich panels(ACHCSP)were investigated usinga combinedapproachof theoryandexperimentation.Atheoretical modelof theACHCSPstructure Was established basedonthe highordersheardeformationtheoryandGibsonequivalenttheory.Thedynamiccharacteristicsof this structureweredetermined usingtheRayleigh-Ritzmethodandorthogonalpolynomialapproach.Arelevantexperimentalplatformwasconstructedtoconduct testsonACHCSPastheresearchsubject,therebyconfirmingtheaccuracyofthetheoreticalmodel.Theresultsindicatethatthis theoreticalmodelcanacuratelypredictthenaturalfrequenciesofACHCSPplates.Basedontheestablishedmodeltheinfluence offiberlayer thickness,oneycombcellwall thickness,andwallengthonthenatural frequenciesofCHCSPstructuresisdiscussed.
