비례솔레노이드 액추에이터용 제어콘 설계에 관한 연구 = New Approach to Design Control Cone for Electro-Magnetic Proportional Solenoid Actuator

다국어 초록 (Multilingual Abstract)

In this paper, steady state characteristics of the electro-magnetic proportional solenoid actuator for pressure control valve determined by the shape of control cone are analyzed using finite element method and it is confirmed that the electro-magnetic proportional solenoid actuator has a constant attraction force in the control region independently on the stroke position. And the shape of control cone is optimized using (1+1) evolution strategy to get a constant force. In the optimization algorithm, control cone length, thickness and taper length are used as design parameters.
In this paper, poppet and valve body which are assembled into the electro-magnetic solenoid actuator were designed and manufactured. Also, manufactured valve was tested using the experimental setup. Through the experimental procedure, characteristics of the manufactured valve were studied and compared to the results of theoretical analysis. The attraction force of proposed model was verified to have about ±2.5% error compared with simulation value
