Fatigue Life Prediction and Reliability Analysis of Airplane Structures Based on Shock Models
Pages: 39-42
Year: Issue:  3
Journal: Aircraft Design

Keyword:  shock modelsstructural componentsfatigue lifereliability curve;
Abstract: Airplane structure fatigue life prediction and reliability analysis is of great significance to airplane design and improvement of the airplane safety. This paper establishes a kind of fatigue life prediction model of airplane structures based on shock modes,w hich is verified by experiment. The result show s that the model is valid to predictthe airplane structure fatiguelife. Then,this paper get the fatigue life distribution curve and reliability curve of airplane structures,w hich is important basic data for airplane design and maintenance
