摘要
根据现代智能微型火工品对电源的需求,设计了三磁钢单绕组磁电动机结构。针对模型进行Ansoft仿真计算,并通过冲击试验台实验,对比冲击实验与仿真计算结果:三磁钢磁后坐电机在过载973 g时,正向峰值电压误差小于7.8%,在工程误差许可范围内;在过载961 g、脉宽1.35ms时,钽电容器充电稳定,电容电压为2.28V,其储存能量为57μJ;过载约2 135 g时,三磁钢较单磁钢、双磁钢的绕组电压都大;过载约535 g时,脉冲宽度由1.10ms增加到2.01ms,绕组电压增加了83.18%。
Taking into account the requirements of the demand of power supply for modern intelligent micro-initiating explosive device,a single-winding magnetor-generator with three magnets is designed.Using Ansoft and a shock test machine,a comparative study of impact is carried out.For the recoil generator with three magnets under 973 g,the error of forward peak voltage is less than 7.8%,which is within the allowable range of engineering errors.With the tantalum capacitor steadily charged at a voltage of 2.28 V,the stored energy is 57μJ under 961 gand a pulse width of 1.35 ms.The voltage of winding with three magnets is higher than those with one or two magnets under 2 135 g.Under 535 g,the pulse width of 1.10 ms is increased to 2.01 ms,with winding voltage increased by 83.18%.
