为弥补现有引信压电电源电能输出少、供电时间短的缺点,文中设计出一种新型引信用钹式压电阵列发电装置,并对其工作原理进行了分析。而后对钹式压电阵列的发电特性进行了研究,并采用总能量求偏导法推导出并联钹式压电阵列的输出电压公式,最后利用Matlab软件进行了数值分析。研究结果表明该新型结构设计能够高效收集诸如发射环境中的冲击能量,在很大程度上提高了压电发电装置的机电转换效率。

To overcome the fuze piezoelectric generator's shortages such as little electrical energy output and short power-on time, a new cymbal piezoelectric array generator was designed for fuze, and its operating principle was studied. Then the generating characteristic of cymbal piezoelectric structure was researched, the formulas of output voltage of parallel connected piezoelectric array were obtained through total energy partial differentiation method. Finally, Matlab was used to preced numerical analysis for the model of piezoelectric generation. The research results indicate that this new structural design could collect impact energy around projectile launch environment effectively, and increase the electromechanical conversion efficiency of piezoelectric generator greatly.
