摘　　要：本文研究作为迫击炮弹引信电源的涡轮电机的模拟问题。首先在理论上分析了迫击炮弹的典型弹道特征,对涡轮电机速度/频率的数学关系和涡轮电机全弹道的输出特性进行了理论推导。然后利用实际迫弹引信涡轮电机的吹风实验数据,拟合得到涡轮电机全弹道频率响应曲线。最后在理论推导的基础上设计了模拟涡轮电机输出的硬件电路和软件程序,作为迫弹引信的模拟供电电源,并实现了引信信号的自动采集、分析和判别。实验结果表明本文设计的迫弹引信涡轮电极模拟信号源满足科研生产的实际要求。In this paper, the simulation of the mortar fuze turbine alternator is studied. The typical trajectory characteristic of the mortar is analyzed, the wind speed/frequency relationship and the whole trajectory respond of the turbine alternator are deduced. The real experiment data of the mortar fuze turbine alternator is used to fitting the curve of the whole turbine alternator trajectory respond. The hardware and software of the virtual source is designed to simulate the voltage and frequency of the turbine alternator, the signal of the fuze is acquired, analyzed and judged automatically. Experiment result indicates that the virtual source of the turbine alternator meets the application requirements of research and production.
