炮口可实时装定的精确计时、定距引信要求内置电源在弹丸出炮口前能可靠地对引信电路供电 ,即要求引信电源的激活时间短。本文对一种用于机电引信的新型可蓄能压电电源的工作原理进行了分析研究 ,建立了该电源在外力作用下蓄能过程的数学模型 ,分析了其主要参数对蓄能速度和蓄能能量的影响 ,并对其在高炮引信中的应用进行了研究。该压电电源具有激活时间短的特点 ,适用于对低功耗电路的短时供电 ,可作为某些精确计时。

A precise timing or ranging fuze that can load information at the muzzle, demands that the power supply deposited in the projectile can provide electric energy for the fuze circuit reliably before the projectile passes muzzle. Studies a new energy storage piezoelectric power supply that can be used in a mechanical electronic fuze, and its mathematical model is established in the energy storing process. Chief parameters affecting the storage of energy in speed and capacity are analyzed. The power supply can be activated instantly. It can provide energy for a low consuming energy circuit in little time and can be used in precise timing or ranging of fuzes.
