Abstract

To experimentally quantify the fatigue life of critical airplane
components (such as, for instance, the slat tracks), extensive tests
must be performed on a test rig. In this paper, a method is proposed to
design the load signal which has to be applied in order to exactly
obtain a certain damage content. The method presented uses a
(band-limited) perturbed multisine (MS) excitation signal. Therefore,
the load can be easily controlled. In addition, because the designed
multisine is periodic, the health of the structure can easily be
monitored on-line. The proposed method will be validated both on
simulations and on (low cycle) fatigue measurements of a steel beam.
