双自旋卫星姿态运动的解析解

本文采用积分因子法较简单地求得双自旋卫星在零马达力矩条件下姿态运动微分方程组的首次积分。文中讨论的方法表明,由于初刻条件选取的不同,可能导致首次解析积分结果的不同表述。

ANALYTICAL SOLUTION OF ATTITUDE MOTION OF DUALSPIN SPACECRAFT

In this paper, We do not use the formula of the energy integral, but on condition that the differential equations directly are integraled by the method of the integral factor, the attitude motion of torque-free asymmetric bualspin spacecraft is discussed, So that exact analytical solution for the attitude motion formulated even perfecter and it's meaning in physiscs can be seen still easier. By the use of the method of this paper it can be discovered that difference between the results of first analytical integral originates from difference to choose the initial conditions in the concrete.
