摘　　要：本文研究带平放式贮箱的三轴定向充液卫星的液体晃动及其姿态动力学问题，建立了充液系统的等效力学模型，并由该模型研究了充液卫星的姿态稳定性。The liquid slosh and the attitude dynamics of a three-axis stabilized satellite with offcentered liquid filled containers are investigated in the present paper.An equivalent mechanical model of liquid filled rigid body system has been set up. Using this model,the attitude stabolity of the satellite is investigated and a stability criterion when the attitude motion is constrained to pitching is obtained.
