摘　　要：分析了多层压电电源的工作原理,分别导出了该电源在冲击力和惯性力作用下的能量公式。指出减小陶瓷片的厚度、增加层数以及选择高值介电常数和高值压电常数的压电材料是提高电源能量途径。并探讨了该电源在小口径高炮引信中应用的可行性。Based on the principle analysis of multiplayer piezoelectric power supply,the energy equations were induced under an impact force or idiomatic force loaded on it.In order to increase output energy,the approaches of decreasing the ceramics chip thickness,adding ceramics chips,choosing a ceramics material whose dielectric constant ε and piezoelectric voltage constant g_(33) are high values should be adopt.And the feasibility of the power supply used in air defense artillery pill fuze was investigated.
