Analysis of Fast Response Characteristics of Solenoid Actuator for Pneumatic Valve

공기압 밸브 개폐용 솔레노이드 액츄에이터의 속응성 해석

The plunger speed of solenoid actuator is affected by mass of plunger magnetic motive force. inductance, and return spring. These factors are not independent but related with each other according to design characteristics of solenoid actuator So, it is impossible to change the designed value for the purpose of increasing plunger speed. In this paper, we performed the FEM analysis for non-magnetic ring which is used for increasing attraction force and plunger speed by concentration of effective magnetic flux, and also performed simulation for dynamic characteristics of plunger. And, we proved the propriety of these by experiments.
