On the Approximate Solution of Aircraft Landing Gear under Nonstationary Random Excitations

비정상 랜덤 가진력을 받는 항공기 착륙장치의 응답해석 기법연구

The motion of an aircraft landing gear over rough runway at variable speed is nonstationary. hi this paper, a method for the computation of nonstationary response variance is presented which uses a state space form for the combination of landing gear and runway excitation. The dynamic characteristics of the landing gear under nonstationazy random excitations has also been analyzed using the proposed method. The formulation is for linear systems of arbitrary order and allows any deterministic velocity history.
