摘要
利用势能函数得出哑铃同步卫星的稳定平衡位置.并通过力学分析说明,由地球引力场的不均匀性所产生的力矩,能够促使同步卫星实现自动姿态稳定.
Potential energy function is used to locate the stable balance position of dumbbell - shaped synchronous satellite. Dynamics analysis shows that moment caused by asymmetry of gravity field can lead the atti- tude of synchronous satellite to be stabilized automatically.
