Mathematical model and experimental verification of high flow cartridge servo valve

KONG Xiao-wu,WEI Jian-hua(State Key Laboratory of Fluid Power Transmission and Control,Zhejiang University,Hangzhou 310027,China)  
Mechanism analysis of the cartridge servo valve was done to solve problems that the cartridge servo valve exhibits serious nonlinear characteristics in the high velocity and high flow electro-hydraulic servo system and its mathematical model cannot be linearized in theoretical analysis.The pilot valve's model was simplified as a linear second-order equation with the ranges of the input and output variables limited,and kinetic analysis of the main spool was done.A compact nonlinear mathematical model of the cartridge servo valve was established.A test platform was set up to verify the mathematical model.The experimental results showed that the step response of the main spool displacement exhibits a great pure delay and the step response time increases with the step amplitude.Comparison between experiment and simulation based on the mathematical model showed accuracy of the model,which proved that the model could be applied to theoretical analysis of the high velocity and high flow electro-hydraulic servo system.
