| 摘 要： | 文章针对伞弹系统欧拉方程奇异性 ,利用正、反欧拉方程精华区、奇异区呈倒挂的原理 ,建立了一套与飞机不同的反欧拉系统。将这套双欧系统应用在克服伞 -弹系统欧拉方程奇异性中 ,取得了满意的结果。同时对双欧法与四元数法计算结果进行了对比验证 ,从而更加清楚地看到了四元数法的方法缺陷和不足 ,为进一步能将双欧法应用于伞 -弹系统六自由度弹道实时仿真进行了有益的尝试

| Abstract: | Making use of the inverse relationship between the ordinary and the reversed Euler equations and thinking of the singularity of Euler equation in parachute-missile system,this paper given a set of reversed Euler equations that different from the plane's.It gets a satisfying result,after using the dual-Euler method in overcoming the singularity of Euler equation in parachute-missle system.Meanwhile, compare the calculated result of dual-Euler method with the quaternion method,it is clear to see the shortage of quaternion method,and it has a good try in the simulation of six dimesion trajectory equation using the dual-Euler method. |
