- Abstract
The paper demonstrates modelling and analysis of the thin circular plate. Numerical and analytical methods were used to analyse the problem. The introduction is about the vibrations of thin circular plate made from steel. Boundary conditions and constitutive equation on dynamics of the plate were shown. Moreover, the model of vibrations of the thin plate was presented. Next part shows the concept of test stand. It is based on Bruel & Kjer impedance tube, Polytec laser vibrometer and white noise generator. The research of thin steel plates was done. The eigenfrequencies and modes of vibrations were found using theoretical and experimental methods. Moreover, comparison between obtained results was shown. Last but one chapter presents the influence of support stiffness on vibrations spectra. Abstract model was used to explain the difference between experimental and theoretical results. The summary of the whole paper includes discussion on the obtained results and synthetic conclusions about vibrations of the considered system. Conclusions also show further application of this investigation.
