A new intelligent fuze safety system based on a linear piezoelectric actuator is proposed in this paper. The liner actuator utilizes the stator’s first-order longitudinal vibration and second-order bending vibration to drive the slider. According to the initial structure size of fuze safety system, parameter design has been carried out and the actuator’s final size has been determined. The prototype is manufactured and frequency-response experiment shows the two vibration modes can be excited at the same approximately frequency. The speed characteristics of the actuator are measured and the maximum speed of 88.2 mm/s is obtained.

Model Transfer

Structural-parametric models, structural schemes are constructed and the transfer functions of electro-elastic actuators for nanomechanics are determined. The transfer functions of the piezoelectric actuator with the generalized piezoelectric effect are obtained. The changes in the elastic compliance and rigidity of the piezoactuator are determined taking into account the type of control.
