Experimental Methods in Acoustic Fatigue.
Abstract
Methods for reducing acoustic fatigue testing time on research, fatigue development, and equipment qualifying tests are presented. Test time reduction include test truncation and testing at higher excitation levels. Statistical developments are based on parametric and non-parametric analyses. Lognormal and Weibull families were investigated as underlying distributions for parametric analyses. The experimental program was directed to reduction of fatigue development test time. Application of methods to typical test situations is discussed. The methods described are intended to be used by aircraft test engineers when performing sonic fatigue or reliability tests on aircraft structural components or equipment items. (Author)
