전자제어식 리버스 연속가변댐퍼용 파일럿밸브의 동특성 해석

Since semi-active suspension systems of automobile, of which suspension damper are controlled actively, exhibit high performance with light system weight, low cost and low energy consumption. From this view point, semi-active suspension systems are greatly expected to be in the mainstream of future controlled suspension systems. In this paper, mathematical modeling and dynamic characteristics analysis of a reverse continuously variable damper and pilot valve used for semi-active suspension systems are investigated. The mathematical model of piston with valve are proposed by IMAGINE/AMESim in the paper. To verify the mathematical model developed, the dynamic characteristics are simulated by AMESim and are compared with experimental results. It was confirmed that the developed models represent well the actual system and can be used for control system design.
