Transient acoustic radiation from excited plates

Research output: Contribution to journalArticle

Abstract

The acoustic radiation time signature as radiated from an infinite elastic plate is obtained for transient forced excitation applied to a point on the plate. The forced excitations considered are those encountered in industrial and marine applications such as the sudden application of dead weight, an impact load, or a sinusoidal finite length pulse that could be generated by starting machinery. The solutions in these cases were idealized by use of a point force whose time history is a step function, a square pulse, or a cw pulse. The time signature for the radiated noise was obtained by convolving the approximate acoustic radiation impulse response solution for an impulsive force with the force time history.
