Abstract

Fatigue damage is one of the main reasons for the failure of aircraft and its structural parts. According to the statistical analysis of practical application, it is found that more than 80% of the strength problems of aircraft in the application process are caused by fatigue damage. Compared with uniaxial fatigue loading, multiple fatigue refers to the fatigue caused by the direction and value of the force changing with the time. Therefore, based on the understanding of various fatigue life analysis methods and the idea of critical surface method, this paper makes a comprehensive analysis of the mechanical structure of aircraft.
