Statistical Energy Analysis for Designers. Part 2. The Engineering Application
Abstract
This report is concerned with the practical applications of Statistical Energy Analysis (SEA) to the prediction of vibration in high speed flight vehicles. The procedures of estimation, based on the theory presented in Part I, are presented in Section I of the report. The authors describe how energy estimates are used to infer stress, displacement, or other dynamical variables. Obtaining the energy estimates is described next, and the SEA parameters - mode count, loss factor, and coupling loss factor are introduced. A discussion of SEA modeling completes Section I. Experimental and analytical procedures for evaluating the SEA parameters are presented in Section II. In Section III, an example of the use of SEA to predict the vibration of an equipment shelf in a reentry vehicle is described in some detail.
