Load Spectrum Determination for Computing and Laboratory Testing
Miodrag Janković Vladimir Zeljković Katarina Maksimović
This paper presents a procedure for the load spectrum estimation based on the recorded working load. For a large number of cycles, the working load can be statistically analyzed and both a type and the parameters of the statistical distribution estimated. On the basis of such a suitable selection of load spectra and their step transformation, it is possible to introduce a systematic approach into this procedure in order to simplify the fatigue testing and the calculation of fatigue damage accumulation and finally the estimation of fatigue life. The load spectra for the wing-fuselage connection are presented. Key words: load, working load, load calculation, material fatigue, protection against load, statistical analysis.
