A Theoretical Study of the Multifrequency Reed Gage for Measuring Shock Motion,
Abstract
A theoretical study of the multifrequency reed gage as an instrument for recording shock motion is presented with particular reference to the various types of shock motion most frequently encountered on naval vessels. The two types of reed gages so far designed at the David Taylor Model Basin are described briefly, and examples of records obtained by each are given. A mathematical analysis of the responses of the individual reeds of the gage to shipboard shock motions is presented on the assumption that each reed behaves as a system of one degree of freedom. Emphasis is placed on the correlation between the measured records and the theoretical responses. Displacement-time curves showing the theoretical responses of a reed to various simple harmonic shock motions are given.
