Design and simulation of a simulated hail launcher based on reluctance coil

  • 摘要: 基于光伏板模拟冰雹撞击试验的实际需求,开展了磁阻型线圈发射装置与脉冲功率源之间的匹配性研究。通过理论对续流前置型和续流后置型两种基本脉冲放电电路进行了适用性分析,结果表明,续流前置型脉冲放电电路与发射装置具有更优的匹配性。针对发射过程中剩余脉冲电流的反向制动问题,设计了一种可以快速消除剩余脉冲电流的泄能电路,用于改进续流前置型脉冲放电电路的拓扑结构,进一步提高其适用性,并借助仿真进行验证。结果表明,泄能电路能快速消除剩余脉冲电流的反向拉力影响,使抛体的发射性能显著提高,抛体出口速度相比传统放电电路提升50.8%,系统发射效率提高127.5%。该项研究可为磁阻式线圈发射技术应用在模拟撞击试验领域的研究提供参考。
