摘　　要：针对目前导弹弹道仿真模型快速生成方法颗粒度粗糙、普适性差的问题,首先建立导弹通用模型架构,通过配置数据文件以快速配装生成所需要的导弹模型;然后,基于全局灵敏度分析的方法对数字配装参数进行灵敏度分析,获得了对导弹性能指标影响较大的参数;最后,进行了仿真验证。仿真结果表明,利用导弹通用模型架构生成的导弹模型准确合理,与公开资料中的性能指标相符;通过全局灵敏度分析,能够快速判断各级燃料质量和燃烧时间等多个参数对导弹射程指标的影响量级。In response to the problems of unprecise modeling and poor universality in current missile trajectory rapid modeling methods,this paper firstly establishes a universal missile framework to ob-tain the missile model through data input and achieves rapid generation of missile models.Then,the global sensitivity analysis method is used to analyze the sensitivity of the missile.Parameters that have a significant impact on missile performance indicators are obtained.Finally,simulation is con-ducted.The simulation results show that the missile model generated using the universal missile framework is accurate and reasonable,and meets the reported performance indicators.The impact of multiple design parameters,such as fuel mass and burn time,on missile range can be determined through the global sensitivity analysis.
