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