INVESTIGATION OF A METHOD FOR THE PREDICTION OF VIBRATORY RESPONSE AND STRESS IN TYPICAL FLIGHT VEHICLE STRUCTURE TECHNICAL DOCUMENTARY REPORT ASD-TDR-62-801

摘要

The prediction of the vibratory response of a complex structure such as an aircraft fuselage or missile to a random external forcing function was the primary task of this project. Previous attacks on the problem have shown it is not possible to estimate vibratory response with useable accur¬acies. Local and remote acceptance, transmission through structure and to substructure, which are all three dimensional phenomena, and randomness are a few of the complexities involved. The timeliness and importance of the study is due to its concern with structural integrity and reliability. The various needs for better handling of new phenomena in structural dyna¬mics are given.
