ON THE CHARACTERIZATION OF VIBRATION SOURCES

摘要

This paper reports an investigation on existing methods for the characterization of vibration sources. The concepts and techniques proposed in the literature are briefly reviewed, andresults and conclusions obtained for the simple case of a source connected to a receptor structure at a single point in one direction are presented. Random and deterministic force cases are treated. The source is a shaker and the receptor structure is either a beam or a plate. The difficulties in obtaining the mobility of the source, used in the calculation of the Characteristic Power, are discussed. Threedifferent methods for obtaining the source mobility are used.
