On the prediction of impact noise, V: The noise from drop hammers
Journal of Sound and Vibration, 1983Abstract In earlier papers in this series, the concepts of “acceleration” and “ringing” noise have been studied in relation to impact machines, and values of radiation efficiency have been obtained for the various types of structural components. In the work reported in this paper the predicted and measured noise radiation from a drop hammer, both in ...

Method of controlling impact force and shock interval in drop hammers
The Journal of the Acoustical Society of America, 1986Method of controlling impact force and shock interval at a drop hammer of the type which has a core (10) and a number of casings (12, 14, 16, 19) arranged concentrically around the core. Between the core and the casings, spacings are arranged, and the core and the casings are interconnected alternatingly at one end and the other beginning at the upper ...
