摘　　要：通过建立末敏子弹组合体大攻角运动双欧拉方程和姿态角互换模型,解决了单欧拉法建模第二旋转姿态角在90°附近时方程精度差、计算发散溢出等难题,实现了刚体全姿态运动的准确仿真。仿真结果分析表明,不同发射条件下末敏子弹组合体的运动姿态、阻力系数明显不同,忽略姿态变化的质点运动模型无法准确描述组合体运动,射表编拟中应采用双欧拉方程。The low precision and calculating overflow problems in single Euler equations when the second rotation angle is near 90 degrees were solved by establishing the dual Euler equations and the attitude angle exchange model for terminal sensitivity bullets combination body which is at high attack motion,and the accurate simulation of the attitude motion of rigid body was realized.The simulation results show that the motion posture and drag coefficient of the terminal sensitive bullets combination body are obviously different under different conditions.The mass point motion model can’t accurately describe the motion of the composite body,the dual Euler equations should be used to compute firing table.
