초록

우주 물체 및 우주 구조물의 초고속 충돌 시뮬레이션을 LS-DYNA를 사용하여 수행하였다. 구형, 원뿔형, 및 속이 빈 원통형의 다양한 형상의 우주 물체는 SPH(Smoothed Particle Hydrodynamics)를 사용하여 모델링하였다. 다양한 두께의 우주 구조물은 직접 충돌 영역과 간접 충돌 영역으로 나누어, 각각 SPH 및 유한 요소를 사용하여 나타내었다. 초고속 충돌에서 금속 재료의 비선형 거동을 나타내기 위하여 Johnson-cook 재료 모델과 Mie-Grüneisen 상태 방정식을 사용하였다. 우주 물체의 형상, 우주 구조물의 두께, 충돌 각도, 및 충돌 속도의 다양한 충돌 조건을 고려하였다. 파편운은 우주 물체와 우주 구조의 초고속 충돌로 인해 발생되며, 발생된 파편운의 형상을 정량적으로 분석하였다. 본 연구의 모든 충돌 조건에서, 원뿔 형상의 우주 물체로 인한 파편운이 가장 위험한 형상임을 확인하였다.

The hypervelocity impact simulations of space objects and structures are performed using LS-DYNA. Space objects with spherical, conical, and hollow cylindrical shapes are modeled using the Smoothed Particle Hydrodynamics (SPH). The direct and indirect impact zones of a space structure are modeled using the SPH and finite element methods, respectively. The Johnson-Cook material model and Mie-Grüneisen Equation of State are used to represent the nonlinear behavior of metallic materials in hypervelocity impact. In the hypervelocity impact simulations, various impact conditions are considered, such as the shape of the space object, the thickness of the space structure, the impact angle, and the impact velocity. The shapes of debris clouds are quantitatively classified based on the geometric parameters. Conical space objects provide the worst debris clouds for all impact conditions.
