Abstract

Taking the main landing gears of fighter and transport airplanes as examples, the fatigue life was estimated by means of the Miner's rule and from the spectrum of the real measurements. The computed results show that the landing damage to the fighter and transport airplanes is 75% and 60% of the total damage, and the damage caused by the landing stroke is 40% of the landing-gear damage. The fatigue damage properties can provide important information for reliable designing and the structural optimization.
