针对导弹适配器分离时间问题,提出适配器分离计算的基本假设,并在此基础上建立适配器分离时间的微分方程,并证明了该方程不能得到解析解,利用Runge-Kutta数值方法得到某型适配器分离时间的数值解.通过对比试验结果可知,该计算方法与试验结果基本吻合.在适配器分离时间数值解法的基础上,分析弹簧刚度、迎风角度、导弹速度以及侧向风速对适配器分离时间的影响规律,经过分析,弹簧刚度和侧向风速是影响适配器分离的主要因素.

Aiming at the problem of separating time of missile adapters, the assumptions are proposed on calculation methods of separating time of missile adapters and differential equations are built, which are not soluble analytically. The numerical solution is obtained of a certain missile adapters by using Runge-Kutta methods. The results of experiments tally with the numerical solution. And the factors are analyzed based on the numerical methods, including the rigidity of spring, the angle against the wind, the velocity of the missile, the velocity of the cross-wind. The results of the analysis show that the rigidity of spring and the velocity of the cross-wind are the main factors.
