고속카메라 영상분석 데이타를 이용한 충격흡수시설의 충돌거동 분석에 관한 연구

Collision behavior of crash cushion occurs for a second of less than 0.4sec usually so that it is too hard to calculate numerically. Therefore, for development of crash cushion, it rely on full-scale vehicle crash test without any design procedure. Occupant safety indices is calculated from acquired data by data measurement system and collision behavior of vehicle and crash cushion is filming using high-speed camera in the crash test. But practical use scope of high-speed camera is limited and it is not using to calculated the occupant safety indices or analyzed the energy dissipated mechanism of crash cushion. This work is to estimate to be suitable or not for compare the data from measurement system with the data from high-speed camera. And also it is to grope for practical use scheme to calculation of occupant safety indices or analysis of collision behavior.
