【 摘 要 】

Thefundamentalfrequenciesofplateareimportant forengineeringdesigns.Freevibrationcharacteristicsofisotropicrectangularplateswithpoint, spring and viscoelastic supportshavebeenstudiedbyseveralresearchers.However, the practical implementation of these boundary conditions in application is not at all trivial. In this study, theeffectsofthe size of thesupportholearea on thefundamentalfrequenciesoftheplatehavebeenanalyzednumericallyandexperimentally.The process involves numerical modeling using finite elements and ANSYS software is used for the analysis of plates. It has advantages such as simplicity in use, applicability to various boundary conditions which solution is not available analytically. The convergence analysis and the analysis for comparison purposes are carried out for the elastic and point supported boundary conditions. For the rigid point supported plate with the specified size of the support area, the experimental study has been conducted and its results compared with the numerical results. The resultsshow that the effects of support size might be considered in engineering vibration analysis of point supported plates.
