Abstract

The accurate mathematical model of the jet-pipe hydraulic amplifier, which is the pilot control stage of a jet-pipe servovalve, is very necessary to analyze and control the performance of a jet-pipe servovalve. In this paper, based on the hydraulic bridge’s flow balance equations, an improved nonlinear explicit model with the absorption effect is developed. The linearized model and valve coefficients are derived from the nonlinear improve model. To test and verify the improved models, the pressure and flow characteristic model of jet-pipe hydraulic amplifier are verified by the experiment. The results show that the model is approximate to the experimental data. In addition, the influence of structural parameters on performance of jet-pipe hydraulic amplifier is analyzed by simulation.
