Abstract
In this article, the radiated noise by a shock-absorber is studied. This particular shock-absorber is used in a heavy-gauge shearing line in order to stop the cut steel sheets. Three steps are followed to evaluate the propagated sound in the surroundings; first of all, the plate vibration response is specified after the impact. Secondly, the edges of the plate are substituted by a set of the monopoles to model the effects of the edges in the sound generation. Thirdly, Rayleigh integral equation is used to calculate the sound generated by the surfaces of the plate. The finite element method is also employed to simulate the problem.
