| Abstract: | The structure and principle of the GMM actuator and the new nozzle flapper valve with GMA are presented. The models on dynamic characteristics of the nozzle flapper valve are established. Experimental system testing the control pressure is also constructed. The output performance of the control pressure is done under typical working conditions. Influence on the control pressure is analyzed with varied input pressures and structure parameters. And matching relation of the different parameters is obtained under the best control pressure. The results show that the nozzle flapper valve has wide pressure control performance, good linearity, and high response speed. And theoretical basis is presented to further introduce the GMA nozzle flapper valve into electro-hydraulic servo valve. |
