Dynamic analysis of a pilot-operated two-stage solenoid valve used in pneumatic system
A dynamic model was developed to study the dynamic characteristics of a pilot-operated two-stage solenoid valve used in pneumatic system. The dynamic model couples motion of the valve spindle with fluid in the system. While solving the system equations, vibration of the valve spindle, characteristic...
