초록

본 연구는 우주 쓰레기를 제거하기 위한 청소 위성(Space debris removal satellite)의 우주 그물(Space-net)을 이용한 우주 쓰레기의 포획 시뮬레이션 연구를 수행하였다. 포획 시뮬레이션은 비선형 구조 동역학 해석 코드인 ABAQUS를 이용하여 수행하였다. 정사각형(1 m × 1 m)의 우주 그물 및 30 kg 질량의 정육면체(0.3 m × 0.3 m × 0.3 m) 형상인 우주 쓰레기를 기본 모델로 설계하였다. 기본 모델에 기반하여 포획 과정을 이해하고 포획 성공 또는 실패에 대한 기준을 정립하기 위하여 ABAQUS를 이용한 포획 시뮬레이션을 수행하였다. 또한 우주 그물의 다양한 설계 조건을 고려하여 포획 시뮬레이션을 수행하였으며, 우주 쓰레기를 성공적으로 포획하기 위한 우주 그물의 주요 설계 인자를 확인하였다.

This study conducts capture simulations of space debris using a space-net. The present capture simulations are performed using ABAQUS, a nonlinear structural dynamics analysis code. A square space-net with 1 m × 1 m and a space debris with a cube configuration(0.3 m × 0.3 m × 0.3 m and 30 kg) are considered as baseline models. Using the baseline models, the capture simulation using ABAQUS is conducted to understand the capture process and establish the criteria of capture success or fail. In addition, the capture simulations are performed when various properties of the space-net are considered, and it is investigated that major design factors of the space-net are recognized to capture successfully the space debris.
