Research and Application of Technology for a New Piezoelectric Ceramic Actuators

文中介绍了一种新型的压电驱动器技术,驱动器通过调节相邻两根陶瓷杆的伸长量,经机械放大后再耦合可在横向圆周预定方位输出角位移。在此基础上,建立了驱动器的力学模型和耦合数学模型,该驱动器在制导弹箭上具有潜在的应用价值。该研究可为制导弹箭弹头的偏转驱动装置设计提供参考。

The technology for a new piezoelectric ceramic actuator is depicted, the actuators change the elongating scale and couple the displacement magnified, it result to the angle displacement output in the preconcerted orientation. Base on the concept, the dynamics model of actuators and coupling math model are built, and the actuators have potential value in application for guided shell. The research can provide the reference for the design of actuators which be used to drive the warhead.
