| Abstract: | As one of the best piezoelectric materials, PZT ceramics is widely used in actuator design and manufacture. This paper demonstrates the positive and negative piezoelectric effect of PZT material, as well as mech electric coupling principle of relevant piezoelectric actuator. In pertinence to the characters of aerospace adaptive truss structure, PZT piezoelectric actuator is applied in vibration suppression test and favorable results are obtained. |
