The present invention relates to a technology for estimation spring constant and damping coefficient of a flying object landing gear, and more specifically, to a method and an apparatus for estimating spring constant and damping coefficient for a high fidelity modeling of a landing gear through a real drop test utilizing a stepped drop jig of a flying object equipped with the landing gear. According to the present invention, through estimating dynamic spring constant coefficient of the landing gear, a landing gear material as landing and putting to earth is able to exactly copy a response nonlinear dynamic characteristic.

    본 발명은 비행체 착륙 장치의 탄성/감쇠 계수 측정 기술에 관한 것으로서, 더 상세하게는 착륙 장치가 장착된 비행체의 계단식 낙하 치구를 활용한 실제 낙하 시험을 통해 착륙 장치의 고 충실도(High Fidelity) 모델링을 위한 탄성 계수/감쇠 계수 추정 방법 및 장치에 대한 것이다. 본 발명에 따르면, 착륙 장치의 동적 탄성 계수 추정을 통해 착륙 접지시의 착륙 장치 천이 응답 비선형 동특성을 정확하게 모사할 수 있다.
