摘　　要：在地球万有引力场和磁场中,考虑大气阻力的条件下,讨论无结构内阻尼的磁性刚体航天器在圆轨道上出现的混沌问题.根据动量矩定理建立动力学模型,利用Melnikov方法证明发生混沌的可能性,并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.In the environment of earth gravitation and magnetic field, the influence of aerodynamic drag was considered. The chaotic phenomenon was discussed when the magnetic rigid spacecraft without internal damping was on a circular orbit round the earth. The dynamical model was established by the law of moment of momentum. The Melnikov analysis was carried out to verify that the chaotic phenomenon is possible, and the numerical simulations were used to analysize the systematic dynamical motion. The theory analysis results agree with numerical simulations.
