摘　　要：以单质量块滚转通道变质心控制再入飞行器为研究对象,研究变质心控制飞行器动力学建模技术及其运动机理。基于牛顿力学建模法及多刚体理论建立了变质心控制再入飞行器动力学模型,并对因质量块运动产生的力矩进行了分析。仿真结果表明,由质心偏移引起的附加气动力矩是变质心控制的主导控制力矩,且质量块的不同安装位置及质量比将影响控制性能。This article studied the dynamics modeling technology and motion mechanism of the movingmass control vehicle with the use of rolling channel of a moving-mass roll control reentry vehicle with sim- ple mass block. Based on the Newton mechanics modeling method and the multi-rigid body theory, the dynamic model of the moving-mass reentry vehicle was established, and analyzed the moments caused by mass movement. Simulation results show that the additional aerodynamic moment caused by the mass block offset is the dominant control moment. Meanwhile, the control performance is effected by mass block＇s installation position and the mass ratio.
