Abstract

This paper is the first paper among two papers which constitute the paper about the rigid body dynamic analysis on the spent nuclear disposal canister under accidental drop and impact on to the ground. This paper performed the general theoretical study on the rigid body dynamic analysis. Through this study the impulsive force which is occurring in the spent nuclear fuel disposal canister under accidental drop and impact to the ground and required for the structural safety design of the canister is intended to be theoretically formulated. The main content of the theoretical study is about the equation of motion in the multibody dynamics. On the basis of this study the impulsive force which is occurring in the multibody in the case of collision between multibody is theoretically formulated. The application of this theoretically formulated impulsive force to computing the impulsive force occurring in the spent nuclear fuel disposal canister under accidental drop and impact to the ground is investigated.

본 논문은 두 편으로 구성된 사고로 지면에 추락낙하 충돌하는 고준위폐기물 처분용기에 대한 기구동역학 해석 논문 중 첫 번째 논문으로 기구동역학 해석에 대한 일반 이론연구를 수행하였다. 이를 통하여 고준위폐기물 처분용기의 구조 안전성 설계에 요구되는 처분용기 처분 시 사고로 추락낙하 하여 지면과 충돌하는 경우 처분용기에 가해지는 충격력을 이론적으로 구하고자 하였다. 이론 연구의 주된 내용은 다물체 동역학의 운동방정식에 관한 것이며 이를 토대로 다물체간 충돌 시 발생하는 충격력을 구하는 문제를 이론적으로 다루었다. 이렇게 이론적으로 구한 충격력을 처분장에서 처분용기 운송 시 운반차량에서 사고로 추락낙하 하여 지면과 충돌하는 처분용기에 발생하는 충격력을 구하는 문제에의 적용을 검토하였다.
