Dynamic Test Results Assessment on the Optical Bench of LEO Satellite

저궤도 지구관측위성의 광학탑재체 지지구조물 동환경시험 결과분석

This paper is an assessment on the dynamic test results of optical bench for LEO satellite. According to the design requirements, optical bench was designed and manufactured. Dynamic test was performed to verify stability of optical bench. Low level random vibration test, sine burst test and sine vibration test are carried out to identify dynamic characteristics and to verify static strength and safety under quasi-static load conditions. From the result it can be stated that the optical bench is well qualified under the launch environmental conditions.
