摘要
通过对已在外场使用停放24年的某飞机机翼的有限元分析和全尺寸疲劳试验,得出腐蚀和腐蚀疲劳对该飞机结构使用寿命的影响及该机疲劳承载能力,定量分析了腐蚀环境对飞机结构及使用寿命的影响.
By fatigue test, FEM analysis of a wing of an aircraft, which has served for 24 years in Navy, the effect of corruption or fatigue corruption on the aircraft structure service life can be seen. Thus we can calculate the aircraft＇s of fatigue load and even quantify the corruption effect. It will be useful to research of aircraft service life.
