本文针对大型弹道式飞行器传统建模和仿真方法的局限性，采用多种运动形态一体化建模方法， 建立了飞行器全干扰、全量、全通道、时变非线性六自由度模型， 并进行了数字仿真和接入部分实装的半实物仿真。该模型已在控制系统设计、系统质量评估、误差分析与精度评定、飞行效果预报和发射技术决策等领域中应用并获得了良好效果， 证明该模型与传统三自由度模型相比更正确、更符合实际， 深化了系统分析与仿真的研究 Aiming at the limitation of the traditional modeling and simulation methods for large ballistic vehicles, this paper established a model of six-degree-of-freedom full-range, full-range, full-channel and time-varying nonlinear six degrees of freedom using a variety of integrated motion modeling methods. Digital simulation and access to some of the actual implementation of the simulation. The model has been applied in control system design, system quality evaluation, error analysis and accuracy evaluation, flight effect prediction and launch technology decision-making and has achieved good results. It proves that the model is more accurate than the traditional three-degree-of-freedom model and more In line with reality, deepen the system analysis and simulation studies
