Fundamentals of Vibration Analysis

AbstractELECTRICAL engineers' handbooks have become both bulky and inconvenient, and contain much duplicated matter owing to the rapid development of the various branches of engineering. In this series it has been decided to publish the fundamental material which forms the basis of all engineering in a separate volume, and the existing handbooks as they are revised are being issued in several volumes containing material closely connected with the specialized branch considered. The entire new series of handbooks will give much more complete information on all topics of interest to engineers.Electrical Engineers' Handbook
 (Vols. 4 and 5 of Wiley Engineering Handbook Series.) 4: Electric Power. Prepared by a Staff of Specialists under the Editorship of Dr. Harold Pender William A. Del Mar Knox McIlwain. Third edition rewritten. Pp. xiv + 1268 + 37. (New York: John Wiley and Sons, Inc.; London: Chapman and Hall, Ltd., 1936.) 30s. net.

Electrical engineers' handbook

An outline is presented of the analysis, engineering study, and theoretical investigation of the steady-state vibrations and the sudden-impulse-shock dynamic characteristics of a new military airborne gimbaled system A mathematical model is described which consists of three mathematical regimes--each defining the distribution of dynamic masses and motions for one plane of excitation Comprehensive recursion tables for the three regimes were filled out by the high-speed No 704 Digital Computer Dynamic-equation matrix coefficients were determined for each frequency Where the error function was zero, the recursion tables were filled out to determine true mode shapes and distributions Additional programming determined forcing-function responses and, through the use of open parameters, determined the effects of modifying masses and other elements of the system Aerodynamic loads for extreme flight conditions were rigorously investigated, and margins-of-safety were determined It is reported that this mathematical method led to recommendations for weight savings, as well as improvement in the dynamic characteristics of the system
