FATIGUE LOADS APPLIED ON A FULL-SCALE STRUCTURE IN RANDOM AND PROGRAMMED SEQUENCES.
Abstract
For an investigation on the equivalence of random and programmed fatigue loads eight full-scale wing center sections were tested. The report describes the load sequences applied in the tests. The random sequence was derived from a strain-gage record obtained with an aircraft flying in turbulent air. This record was amplified and adapted to the fatigue machine. The statistical properties as obtained by several methods, counting peak loads or load ranges, are presented. The load sequence for the program tests and the assessment of the ground-to-air cycles are described. The loads applied in each of the eight tests are summarized. Brief comments on the results are given. (Author)
