建立了一种基于空空导弹制导系统虚拟样机的引战系统仿真模型,用于研究导弹对目标的毁伤过程、引战配合效果以及引信和战斗部参数优化等。以制导仿真输出的实时弹道信息和目标三维外形为基础,构造了引信探测、延时起爆、战斗部飞散、毁伤计算等模型,仿真结果输出到视景仿真模块,用于末端交会过程的实时显示。引战仿真和制导仿真、视景仿真连接后,构成了完整的空空导弹虚拟样机。该虚拟样机运行效果良好,验证了引战仿真系统建模的合理性。

A fuze warhead system model based on virtual prototype of air-to-air missile guidance system was built for studying the missile terminal destroy process at target, fuze-warhead coordination effect and fuze warhead parameters optimization. Based on the real-time trajectory information of guidance simulation output and three-dimensional object shape of target, the fuze detection, de-layed explosion, warhead dispersion and damage effectiveness calculation were constructed to really display terminal encounter process. The fuze warhead simulation model was connected with guidance simulation subsystem and visual simulation subsystem to form integrated air-to-air missile virtual prototype. The virtual prototype ran well and the rationality of fuzzed warhead subsystem simulation model was validated.
