针对国内诱饵弹半实物仿真技术和红外制导技术研究的迫切需要,提出了针对诱饵弹干扰特性的有限元建模方法。通过分析诱饵弹的工作机理和运行状态,借助有限元方法建立诱饵弹的温度流场分布和空气变阻力运动特性模型,并通过仿真实验验证所提出模型的有效性和正确性,该方法不仅能为红外诱饵弹的设计和红外制导算法的研究提供依据,也对红外半实物仿真系统的搭建有重要指导意义。
In view of the urgent need of semi-physical simulation of decoy bombs and infrared guidance technology in China, a finite element modeling method based on the characteristics of bait bombs was proposed. By analyzing the working mechanism and operating status of the decoy bombs, the temperature field distribution and air resistance of the decoy bombs were established by means of finite element method. The validity and correctness of the proposed model were verified by simulation experiments. It provides the basis for the research of IR decoy and IR guidance algorithm, and also has an important guiding significance for the establishment of IR semi-physical simulation system.
