在力矩平衡和导弹无滚转运动假设的基础上，考虑导弹的推力矢量控制力和过载响应特性，采用四元数描述导弹速度方向，建立了包含导弹姿态信息的三自由度弹道仿真模型。仿真结果表明，所建立的三自由度模型可以准确、快速地计算导弹的飞行弹道，同时避免导弹运动方程的奇异问题。

Based on the assumption of moment balance and no roll movement,considering the thrust vector control force and the acceleration response characteristics,a three-degree-of-freedom trajectory simulation model which contains orientation information is established by using quaternion to describe the velocity di-rection of missile. The simulation results show that the model could precisely and rapidly calculate the traj-ectory. The singularities problem of movement equation is also avoided.
