Application of Piezoelectric Actuator in Fuze Safety System

针对某些引信安全系统中解除保险的原动力来源于电驱动做功火工元件,解除保险时间不精确、炮口保险距离可控性差的问题,该文提出将一种行波旋转型压电精密驱动器应用到引信安全系统中驱动隔爆转子的动作。设计了驱动机构,分析了压电驱动器的工作原理及其应用的可行性。研究结果表明,压电精密驱动器可使引信安全系统解除保险过程精确可控,结构紧凑,体积小。

In view of that the motive force to remove safety in most electromechanical fuze safety system is electricity-drive initiator component, the time of removing safety process is not accurate and the muzzle safety distance is poorly controllable, a traveling-wave revolving piezoelectric actuator is applied to the fuze safety system for driving the movement of the isolating explosion rotor. The drive mechanism is designed. The piezoelectric actuator working principle and the application feasibility are analysed. The research results show that the piezoelectric actuator makes the removing safety process accuratly controlled and the fuze safety system smaller.
