摘　　要：刚体六自由度运动仿真是飞机、火箭、导弹及舰船等载体运动仿真的基础，能较好的反映出刚体的运动本质。针对刚体六自由度运动，介绍了三大常用坐标系定义，在此基础上建立了舰船六自由度运动方程，利用MATLAB／SIMULINK的Aerospace工具箱建立了一般刚体的六自由度仿真模型并进行了两组对比仿真实验，实验结果表明轴向高速旋转有助于保持舰船法向和横向的稳定性。The rigid body six-degrees-of-freedom simulation is the basis of the movement simulation for missile, airplane, missile and so on.The three normal coordinate systems and the equations for the movement of the rigid body six-degrees-of-freedom in this three coordinate systems are introduced The model of six-degrees-of-freedom movement simulation for rigid body is constructed based on aerospace block-set of Matlab/Simulink is presented and two contrast simulations are carried out.It is indicated that the high axial rotating rate is helpful for stability of normal and lateral directions by the experiment results.
