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.
