This study investigates the vibrational behavior of 15×15 cm rectangular metal and plastic plates using both finite element analysis (FEA) and experimental measurements. The research aims to compare simulation results with real-world experimental data to validate the accuracy of numerical models in predicting plate vibrations under excitation from a speaker. Initially, modal analysis is performed via FEA to determine the natural frequencies and mode shapes of the plates. The numerical simulations are conducted using appropriate boundary conditions and material properties to ensure realistic modeling. Subsequently, an experimental setup is designed to excite the plates using a modal hammer, modal shaker and sound exciter. Thus, the resulting vibrations are measured using accelerometers and acoustic microphone. The measured frequency response is then compared with the FEA predictions to assess discrepancies and potential sources of error. Results indicate that while the FEA models provide a good approximation of the experimental outcomes, differences arise due to material imperfections, boundary condition assumptions, and damping effects not fully captured in simulations. The findings contribute to a better understanding of plate vibration characteristics, with implications for applications in acoustics, structural engineering, and materials science.
