摘　　要：提出一种适用于空间太阳能电站的长期轨道动力学模型。以运行在地球静止轨道的Abacus型空间太阳能电站为对象,首先,为避免轨道倾角与偏心率为0产生的奇异,介绍并采用米兰科维奇矢量描述空间太阳电站的轨道动力学,依次建立影响其轨道的4种摄动模型,包括地球非球形引力摄动、日月引力摄动、太阳光压摄动以及微波反冲摄动。随后,进一步分析轨道摄动中的周期项与非周期项,采用平均法对摄动中的周期项进行平均化处理,建立基于米兰科维奇矢量的空间太阳能电站长期轨道动力学方程。最后,通过数值仿真与传统非平均法模型进行对比,以验证所提出平均化动力学模型的优势。A long⁃term orbital dynamic model for SSPS(Space Solar Power Station)is proposed in the paper.To avoid singularity of inclination and eccentricity,the Milankovitch vector is introduced and adopted to establish the orbital dynamic model.Focusing on the GEO Abacus SSPS,the four perturbation models,including solar and lunar gravitational attraction,terrestrial harmonic,solar radiation pressure and microwave radiation force,are successively derived.The periodic and non⁃periodic components of perturbations are then analyzed,and the averaging method is used to tackle the periodic component.Therefore,the long⁃term orbit dynamical model which is applied to SSPS is presented.Numerical simulations are finally provided to illustrate the advantages of proposed long⁃term model by comparing with the non⁃averaging model.
