摘　　要：阐明了PZT压电材料的正、逆压电效应以及相应的压电作动器的机电耦合原理。针对航天自适应桁架结构的特点 ,运用PZT压电作动器进行了振动抑制实验并取得了良好的效果。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.
