| 摘 要： | 以分离条件恶劣的搭载星为对象,对其与运载火箭分离的过程进行了研究。通过对物理模型的分析,建立了动力学方程;通过对各种干扰因素的分析,计算了共同作用的扰动力矩,最终得到卫星分离的速度、卫星姿态参数和星箭相对位置。

| Abstract: | This paper described the separation dynamics process of a microsatellite as a piggyback payload from a launch vehicle.Dynamics equations are built up on the basis of analyzing the physical model and the interfering moment resulted from many kinds of disturbing factor is calculated.At last,velocity attitude of the satellite and dimensional distance between the satellite and the rocket are given during separation. |
