Predicting Fatigue Life of A Mount of A Device with Shock Absorber

All aircraft operate under vibration loads and these cause vibration-induced fatigue damage to the parts. Fatigue damages are dangerous because they occur suddenly without giving a warning before, for this reason need be carefully analyzed. In analysis, especially natural frequencies dampings must determined correctly, when match with frequencies, resonance is observed reduces life of part. study, mount device shock absorber investigated. Flight tests were carried out in real flight scenarios provide an input analysis. A modal test was performed model absorbers correctly. Vibration prove accuracy prepared finite element determine damping ratios. analyses frequency domain commercial software, nCode, analysis proven by experiment.
