摘　　要：研究了太阳帆悬浮轨道的动力学特性,主要分析了稳定性条件。首先建立垂直于太阳-行星连线的悬浮轨道模型,在柱坐标系下,依据Hamilton原理得到悬浮轨道角动量与太阳光压的关系。然后,针对小扰动情况运动方程,分析悬浮轨道线性与非线性稳定性条件。最后,运用Hamilton-Jacobi理论进行变量分离,得到物理意义明显的动力学方程。仿真结果表明,选取合适的初始值,可以实现稳定的太阳帆悬浮轨道。This article studies kinetic characteristic of solar sail displaced orbit and analyses stability con- ditions. Firstly, by establishing displaced orbit model which is normal to sun-planet and assuming solar radiation pressure as constant, the relationship between displaced orbit angular momentum and solar radi- ation pressure can be derived through Hamilton dynamics method. Considering small perturbations of mo- tion equation, the stability condition of linear and nonlinear displaced orbit can be derived. Finally, u- sing Hamilton-Jaeobi theory, the kinetic equation with significance physical meaning can be derived by variable separation. Simulation results show that stable solar sail displaced orbit can be realized by choo- sing proper initial value.
