空间结构的在轨展开涉及到复杂的高维强非线性动力学问题,这些动力学问题的建模及仿真技术是航天动力学领域的难题,也是对在轨展开过程施加控制的前提条件.本研究以IKAROS太阳帆在轨第一阶段展开过程为例,基于哈密顿变分原理,建立中心刚体-主动伸长柔性梁耦合动力学模型;采用保结构分析方法,关注动力学系统的局部动力学行为,在恒定转矩驱动和恒定功率驱动两种工况条件下,对IKAROS太阳帆第一阶段展开过程进行仿真;发现两种工况条件下的中心刚体转动角速度演化规律差别显著,恒定转矩做功将导致中心刚体的转动稳定性变差,同时,恒定功率驱动工况下,IKAROS太阳帆第一展开阶段节能效果较好.
The on-orbit deployment of the spatial structure involves the complex high-dimensional nonlinear dynamic problems,the analysis on which is one of the challenges in the astrodynamics field and the precondition of performing the control strategy on the on-orbit deployment process.In this paper,taking the 1st deploying stage of the IKAROS solar sail as an example,the flexible stretching hub-beam model is proposed and the dynamic equation for which is presented based on the Hamiltonian variational principle.Employing the complex structure-preserving method which focuses on the local dynamic behaviors of the system,the 1st deploying process of the IKAROS solar sail is simulated under two working conditions(invariable torque and constant power)respectively.The numerical results show that the differences between the rotational velocities of the hub for the two cases are remarkable.The rotational stability of the hub turns bad with the invariable torque,which results in the large work needed in the 1st deploying stage of the IKAROS solar sail and implies that the constant power working condition can save energy in this process.
