Abstract
In this paper, a new electric-pneumatic convert device with piezoelectric composite disc as actuator is proposed. The new convert device break through traditional principle of force balance, which the parameters optimization to the whole air course and the structure of piezoelectric actuators were carried on by orthogonal experiment method. Experimental results show that the new device character is effected seriously by original installation site and has the characters of fast response, sensitive reaction, stable performance and meet the requirement of air pressure output between 0.02MPa and 0.1 MPa in industrial field with low voltage, which provides good basis of development of electric-pneumatic convert valve with new piezoelectric structure.
