Analysis of Vibration and Acoustic Sound Radiation of a Rotationally Symmetrical Plate

Abstract

The importance of studying the vibration and acoustic radiation of symmetrical plates lies in its widespread applications across various engineering disciplines. Symmetrical plates are fundamental structural components found in aerospace, automotive, marine, and civil engineering systems. This study is focused on vibration behaviour and acoustic sound radiation of a rotationally symmetrical plate. Therefore, analysing the vibration behaviour of a rotationally symmetrical plate can be helpful to optimize the mechanical and acoustic properties of such structures. Sweep operation, Lissajous curve and stochastic excitation methods have been used to determine the natural frequencies. The acoustic radiation is measured at various frequencies and distances from the plate using a calibrated microphone.
