Abstract

The design of the main control valve, which is the main component of the flap control system, was based on actual manufacturing experience on the basis of trial and error method. In this paper, a model-based part design method is proosed. The flap control system consists of a main control valve, fail-safe valve, solenoid valve, LVDT and force motor. The main control valve consists mainly of a spool and slot. The important design parameters of the main control valve are the slot width, overlap and clearance. AMESim is linked to the model and it analyzes the flow path of the main control valve. Applying the proposed design procedure, it was confirmed that the required performance was satisfied within the allowable machining error range.

플랩제어시스템의 주요 구성품인 주제어밸브의 설계는 실제 제작 경험을 바탕으로 반복-오차 방법에 의존하여 수행하였다. 본 논문에서는 모델 기반의 부품 설계 방법을 제안하였다. 플랩제어시스템은 주제어 밸브, 고장-안전 밸브, 솔레노이드 밸브, LVDT, 구동 모터 등으로 구성된다. 주제어밸브는 주로 스풀과 슬롯으로 구성된다. 주제어밸브의 중요한 설계변수는 슬롯의 폭 (Slot Width), 오버 랩(Overlap) 및 간극(Clearance)이다. AMESim을 활용하여 주 제어 밸브의 유로를 모델링하고 해석하였다. 제안된 설계절차를 적용한 결과 허용된 가공오차 범위 내에서 요구 성능을 충족함을 확인하였다.
