Abstract:
This paper propose a single-stage valve system actuated by a piezostack actuator and control performance is experimentally evaluated from room temperature to high temperature(150℃). In order to achieve this goal, a design of a piezostack driven single-stage valve system is proposed and an experimental apparatus is manufactured to evaluate the valve performance with high temperature conditions. The experimental apparatus consists of a heat chamber, pneumatic-hydraulic cylinders, a hydraulic circuit, a pneumatic circuit, thermal insulator, and electronic devices such as computer, Data acquisition (DAQ) board, sensors, and a high voltage amplifier. The displacement control performance of the valve system is evaluated via experiment. In order to evaluate of performance with high temperature, the piezostack valve system is heated and controlled at the inside of heat chamber. The experiment results are compared between room temperature condition and high temperature condition. Control of displacement tracking is evaluated and compared between room temperature and high temperature.
