摘要: 利用能量-Casimir方法研究了带4个挠性粱的充液卫星系统在无外力矩状态下,关于绕铅垂轴稳态转动的非线性稳定性条件,该条件考虑了液体的涡旋、弹性梁的振动、卫星主刚体的旋转以及流-弹-刚之间的耦合,此外还考虑了离心力与Coriolis惯性力的影响。推广了Rumjantsev和Marsden的部分结果,为带挠性粱的充液航天器的运动稳定性总体设计提供了可靠的理论依据。

Abstract: Nonlinear self-spinning stability criteria of liquid-filled satellite with fotir-flexible-appendages are investigated with the Energy-Casimir method.The stability condi-tions take into account the vorticity of the liquid,the vibration of the flexible appendages,rota-tions of the rigid satellite,the coupling of liquid-elasticity-rigid,and centrifugal and coriolis forces.These results which are the extension of Rumjantsev's and Marsden's are obtained for the first time.

Key words: liquid-filled satellite, flexible appendages, Energy-Casimir method
