Using a Computer Display to Model a Complex Vibrating Surface

Abstract

Vibration waveforms are taken at several points on a vibrating surface and then combined, using a computer with a cathode-ray-tube display, to produce several representations of the movement of the surface. An important advantage of this method is that the forms of the data and representations lend themselves readily to manipulation by the computer. A noncontact vibration pickup, developed especially for this application, is briefly described.
