In order to predict the flow field distribution,analyze the design rationality and specify the structural optimization direction of electric-controlled pressure amplifier,the three-dimension flow field model of it is built by FIRE software,the three dimensional flow simulation analysis of pressure amplifier is conducted based on the model,and the flow field pressure and velocity change and distribution during the pressurization process are obtained.Results show that when the flow field of pressurization oil circuit is at the end of compression stroke,the highest pressure mainly distributes around the outlet of electric-controlled pressure amplifier,and the maximum velocity mainly distributes around the oil inlet passage of one-way valve chamber and pumping chamber.When the flow field of control oil circuit is at the end of compression stroke,the pressure in control volume reduces greatly,and the pressure of control volume outlet orifice is less than the critical pressure during the pressurization process,which may lead to the occurrence of gasification phenomenon.
