Design and Dynamic Characteristics Simulation Reserch of Pneumatic Solenoid Valve
According to the technical specifications of pneumatic solenoid valves,a model simulation was conducted based on AMESim,and the structural dimensions and dynamic response time parameters of the solenoid valve were determined.The results showed that the closing time of the solenoid valve was 66 ms,far greater than the requirement of response time≤10ms in the technical specifications.Through analysis,it is found that the main reason affecting the long closing time of the solenoid valve is that during the closing process of the solenoid valve,the coil voltage changes slowly,and its magnetic flux also decreases slowly,which causes eddy currents in the valve core and hinders the movement of the valve core.By adopting a dual voltage control method,the reverse voltage is increased when the solenoid valve is closed,reducing the closing delay time of the solenoid valve,and reducing the closing time of the solenoid rom 66 ms to 4.5 ms.The correctness of the simulation analysis is verified by experiments.
