摘　　要：针对雷电击中火箭时对火箭内部电气设备造成干扰和损伤等间接效应的防护问题,分析了箭内电气设备的一些共性加固方法,基于箭内典型电气设备受雷电电磁脉冲的干扰途径建立了火箭抗雷电加固设计的传导干扰模型和辐射干扰模型,在此基础上提出了基于粒子群算法的箭内电气设备抗雷电间接效应的最小质量增量设计方法。优化结果表明,所提方法在满足防护指标的前提下控制了火箭的质量增量最小,对提高火箭的总体性能具有十分重要的工程意义。Aiming at the protection of indirect effects such as interference and damage to electrical equipment inside a rocket caused by lightning,this paper analyzes some common reinforcement methods for the electrical equipment in the rocket.Based on the way that these typical devices are interfered by lightning electromagnetic pulse,this paper also establishes a conducted interference model and a radiation interference model for the design of rocket anti-lightning reinforcement.On this basis,a minimum mass increment design method based on particle swarm optimization(PSO)for lightning indirect effect resistance of the electrical equipment in the rocket is proposed.The optimization results show that the proposed method can control the minimum mass increment of the rocket on the premise of meeting the protection indexes,which is of great engineering significance to improving the overall performance of the rocket.
