| 摘要: |
| 基于动力学原理,首先建立了圆形悬挂轨道的相对运动动力学模型,然后在C-W方程考虑非线性扰动情况下,推导出圆形悬挂轨道基于二阶非线性扰动的运动方程,分析研究了非线性因素对悬挂轨道的影响,并给出了具体的修正方法。仿真结果表明,基于相对运动条件下,对圆形悬挂轨道进行的二阶非线性修正消除了Y-bar方向上的长期扰动,为今后的研究奠定了理论基础。 |

| Abstract: |
| A relative motion dynamics model based on the circular suspension orbit is established in this paper, we deduce the motion equations of second-order nonlinear perturbation in the C-W equation.Then the effect of nonlin-ear factors on the suspension orbit is analysed and studied based on the equations.Finally we present a method for implementing the second-order nonlinear perturbation correction of circular suspension orbit.The simulation results and their analysis show preliminarily that, under the condition of relative motion, the second-order nonlinear cor-rection of the circular suspension orbit can eliminate the long-term perturbation in the Y-bar direction and is, we believe, of some help in future research. |
