| 摘 要： | 在地球引力场和磁场中,在考虑了航天器结构内阻尼及气体阻力的影响条件下,研究磁性刚体航天器在绕地球圆轨道运行时可能出现的混沌问题.根据动量矩定理建立动力学模型,应用Melnikov方法证明了动力系统在一定条件下会发生混沌行为,并且给出了解析判据.最后利用数值仿真分析了系统的动力学行为,理论结果与数值仿真结果相一致.

| Abstract: | In the environment of earth gravitation and magnetic field,the chaotic phenomenon is discussed when the magnetic rigid spacecraft is on a circular orbit round the earth under the condition of structural damping and aerodynamic drag.The dynamical model is established by the law of moment of momentum,The Melnikov analysis is carried out to prove that the dynamics system will appear chaotic behavior in certain conditions, and the analytical criterion of chaotic behavior is given.Then the numerical simulations ... |
