摘要:
航天器对接过程的动力学建模是对接过程动力学仿真的核心内容 ,该文在描述航天器对接过程的基础上 ,利用牛顿 -欧拉定理和混合坐标法对带有大型太阳电池阵的两航天器的对接过程进行动力学建模。建模中将对接系统简化为由追踪飞行器、目标飞行器和主动对接机构组成的三体系统 ,追踪飞行器和目标飞行器作为带有挠性附件的中心刚体考虑 ,主动对接机构作为刚性体处理 ,对于挠性附件用有限元法进行离散。除给出接触撞击模型外 ,还重点讨论缓冲系统的简化模型 ,从而构成了对接过程的完整的动力学模型 ,为对接过程的动力学仿真打下基础
Abstract:
Dynamic modeling of spacecraft docking process is a chief content of docking process dy namic simulat ion. Based on the descript ion of spacecraft docking process, dynamic modeling of tw o spacecraf t with large solar panel is performed by w ay of New ton-Eular and mix ed coordinate in this paper. The models simplified the docking system as three bodies consist ing of chasing vehicle, targ et vehicle and act ive ring, considering chasing vehicle and targ et vehicle as centric rigid bodies w ith flexibility appendag es w hich are discreted by way of finite element , and act ive ring as rigid bodies. Besides the g iven contact and impact models, this paper also discusses the simplified model of buffer system. All these const itute whole docking dynamic models and lay foundat ions for dy namic simulat ion of docking process.
