Design of Novel Fuse Generator Based on Cymbal Piezoelectric Array

A novel fuse generator based on cymbal piezoelectric array has been designed in this work. The generating characteristics of cymbal piezoelectric transducer and cymbal piezoelectric array have been studied according to hydrostatic piezoelectric properties, and the power output characteristic of the generator under the ammunition projectile launch environment has been analyzed. The results show that this novel generator can effectively collect the impact energy under the ammunition projectile launch environment, and convert it into vibration energy firstly, then obtain continuous electrical energy. The designed generator increases the power on time, and effectively solves the problems of small electrical energy output and short power on time in the current fuse.
