Analysis of steady-state vibration of rectangular plate supported from four points and passive control applications

In this study vibration of rectangular plate has been investigated for various boundary and load coditions. Theoretical and experimental analyses are made for point supported, spring supported, viscoelastic supported and load applied situations. Natural frequency analysis and harmonic force analysis are made. Finite element method was used in theorotical process. During the experimental studies, FRF (frequency response function) and APS (auto power spectrum) diagrams are drawn. The results are investigated, and suggestions for experimental studies are made. Keywords: Natural frequency, finite element method, experimental modal analysis, vibration.
