“…Electromechanical converters, which are key components of servo valves, have a great effect on their performance. Thus, research on high-speed and high-precision servo valves aims at the replacement of conventional electromagnetic electromechanical converters by high-precision and high-response prestage drivers [1,2]. In recent years, piezoelectric materials have been the primary choice of electromechanical converters because of good linearity, high response, high precision, absence of electromagnetic interference, and easy miniaturization.…”

A piezoelectric actuated prestage driver of hydraulic servo valves for the low-frequency response of electrohydraulic servo valve electromagnetic prestage driver was presented. The new driver was driven by piezoelectric multilayer actuators. The displacement of a piezoelectric multilayer actuator was amplified by a flexure-hinged amplifier based on the principles of triangle amplification. Static and dynamic characteristics were tested on the model machine. The characteristics of good linearity, high resolution, and high-frequency response were approved. The natural frequency reached 1.201 kHz using finite element analysis, and the practice measurement result was 1 kHz.

“…Perfect performance of smart actuators, such as high-response, high power density and compactness can be used to improve the competitiveness of hydraulic products [3] . Compared with the magnetostrictive and solenoid actuators, the piezoelectric (named PZT) actuator has the following advantages: fast response (up to GHz), high output force (kN), low energy consumption (current of mA) and low cost.…”
