摘要
为了培养学员的工程实践能力,帮助他们深入认识电磁发射技术在军事领域的广阔前景,了解电磁炮的理论基础和基本构成,采用多级加速线圈级联的方式,构建了电磁发射实验模型。利用多组红外光电对管实现抛体位置的检测,通过单片机记录抛体通过各组对管的时间,计算出抛体的通过速度,并根据抛体加速过程中各组加速线圈的通断电逻辑关系,实现它们的通断电触发控制。经测试,该模块能够满足实验要求。
In order to cultivate the students＇ engineering practice ability, moreover, help them to realize the bright future of the electromagnetic launching technology in military field and to understand the basic principle and fundamental structure of the Gauss Gun, the experimental model of electromagnetic launcher has been constructed, which adopt the serial-type to combine the multi-staged coils for accumulating. The infrared photodiode has been used to detect the position of the projected subject, and the MCU has been used to record the time when the projected subject arrive to the photodiode and calculate the speed of it. Based on the analysis of when to turn on or off each accumulating coil, the MCU controls the power supply. This module block has been proved to meet the requirement of the experiment in the service test.
