착륙장치는 반복적인 하중을 받는 구조물로써 피로수명 예측이 필요하다. 피로수명 예측 시 필요한 하중 스펙트럼 생성 방안에 대해 소개하고자 한다.
A landing gear experiences fluctuating loads during landing and ground maneuovering. Life of landing gear should be estimated by analysis and qualified by test. Fundamental inputs for fatigue analysis are a load spectrum, material information, a geometry of the component, etc. In this paper, a methodology of a load spectrum generation is introduced for landing gear fatigue analysis.
