摘　　要：针对现有引信压电电源发电时间短的问题,设计制作了以弹簧-质量块和压电换能器为主要部件的引信发电装置。该装置能将弹药发射瞬间的冲击能量收集并转换为持续的电能输出。测试结果表明,冲击加载、换能器结构、换能器层数、质量块等对其发电性能有不同的影响规律,且钹式叠堆结构发电性能优于薄片压电叠堆,所提出改进后的发电装置发电时间能达到2.499s,有效延长了引信压电发电装置的供电时间。Aiming at the shortages that the power supply time of fuze piezoelectric mechanism is too short, a new fuze generator based on spring-mass structure was proposed and designed, which was of different stacks of slice piezoelectric and cymbal structure. Testing results showed the different influence rule of shock level, mass？ layer number and structure to electric parameters of these generators ？ and mechanic-electric transfer characteris-tic based on cymbal stack was prior to that of slice stack. Based on these conclusions. The structure based on cymbal array was brought out, and test results showed that the power supply time could last for 2. 499 s.
