| Abstract: | The method to amplify the displacement of stack-type piezoelectric ceramic actuator was studied.A piezoelectric actuator module that could be using in high pressure common rail injection system was designed.A new micro-displacement amplifying mechanism was presented based on hydraulic transmission theory.The mechanism included a displacement amplifying chamber and two pistons.The piston at the bottom of the amplifying chamber was used to amplify and transmit the displacement of the upper piston.The experime... |
