Abstract

If an actuation system of the tactical missile is required very fast response time on conditions of short operating time and big loads on the actuator, we would prefer to adopt a small hydraulic system. In this paper, a mathematical model is proposed to analyze and simulate the small hydraulic actuation system. The mathematical model consists of a high pressure vessel model, a pressure regulator model, a hydraulic reservoir model and a actuator model. The suggested model is validated by comparison of simulation results with experimental data. The simulation results show that the mathematical model could be useful for designing a hydraulic actuation system.

최근 전술유도무기 분야는 대부분 전기식 구동장치를 채용하고 있으나 주어진 공간조건과 무게 제한 아래 상대적으로 부하가 크며 작동시간이 짧고 동시에 빠른 응답성이 요구될 경우에는 무게 및 공간 조건을 맞추기 위해서 반드시 유압식 구동장치를 적용해야 할 경우가 발생한다. 본 논문에서는 소형 유압식 구동장치 시스템을 대상으로 수학적 모델링과 시뮬레이션을 수행하였다. 수학적 모델은 고압용기, 압력조절밸브, 저유기, 유압작동기로 나누어 구성하였으며 실험 결과와 비교하여 모델의 타당성을 검증하고 고찰하였다. 본 연구를 통하여 소형 유압식 구동장치 시스템 설계에 유용한 수학적 모델을 수립하였다.
