Abstract
-
Study was made of forcing functions and their characteristics, methods of estimating a combined response, and proof tests required to qualify structure and equipment. The report is presented in three parts. Part One discusses the various sources of vibratory energy which can result in vehicle vibration including rocket noise, aerodynamic pressure fluctuations, wind shear and gust, meterorites and direct mechanical coupling. Part Two discusses the prediction of vibratory response through both empirical and analytical approaches, and includes a thorough discussion of the single degree of freedom system, resonance-on-resonance, panels, shells, mobility, generalized force, joint acceptance, correlations and other statistical tools. Part Three contains a discussion of fatigue and malfunction, the properties of an ideal test, implications of and methods for obtaining a simplified composite response and an examination of various test equivalences.
