根据多层压电陶瓷产生电量的理论计算和分析,制作了压电陶瓷堆,利用压电陶瓷在爆炸冲击作用下产生的能量对半导体桥火工品进行了点火试验,并研究了压电陶瓷层数、爆轰激励源大小对点火的影响。结果表明:压电陶瓷片层数越多,其输出电压越高,输出能量越大;施加的爆炸冲击波压力越大,其输出的电压越高,能量也越高。因此,压电陶瓷用于半导体桥点火是可行的。
According to the theoretical calculation and analysis of the electricity generated by multi-layer piezoelectric ceramics, a piezoelectric ceramic stack was fabricated. Ignition experiments were conducted on the semiconductor bridge fire using the energy generated by the piezoelectric ceramic under the impact of explosion. The effects of piezoelectric ceramics The number of layers, the size of the detonation stimulus impact on the ignition. The results show that the higher the output voltage is, the higher the output voltage is. The larger the applied piezoelectric shock wave pressure is, the higher the output voltage is and the higher the energy is. Therefore, the use of piezoelectric ceramics for ignition of semiconductor bridges is feasible.
