Abstract

Electronic of military vehicle that had relied on pure machinery system is ongoing. A large part of electronic of small-sized military vehicle has been already commercialized, which will expand to large-sized military vehicle field. Design of solenoid valve for automatic transmission is significantly important for stable driving performance of military vehicle. This research aims to develop simulation method which is capable of predicting performance of solenoid valve quantitatively according to its variation of ATF temperature. The research has been conducted in line with Maxwell, a magnetic field analysis program, and AMESim, a hydraulic analysis program. After simulation, it turned out to have been very similar to the test result in temperature range which excludes high temperature (over $120^{\circ}C$) and extremely low temperature (below $-20^{\circ}C$).

순수 기계식 시스템에 의존하던 군용차량의 전자화가 진행되고 있다. 이미 소형 군용차량의 전자화는 상당부분 상용화되었으며, 점차적으로 대형군용차량으로 확대될 것이다. 군용차량의 안정적인 주행성능을 위해서는 자동변속기용 솔레노이드 밸브의 설계가 매우 중요하다. 본 연구에서는 솔레노이드 밸브에 대해 ATF온도 변화에 의한 성능변화를 정량적으로 예측할 수 있는 해석(Simulation)수법을 개발하는 것을 목적으로 한다. 연구는 자장해석소프트웨어인 Maxwell과 유압해석프로그램인 AMESim을 연동하여 진행한다. 시뮬레이션 결과 고온($120^{\circ}C$이상)과 극저온($-20^{\circ}C$이하)을 제외한 온도 영역에서 실험결과와 매우 유사함을 보인다.
