摘　　要：为了明确直观地表现自旋弹头姿态运动与控制量之间的关系,采用牛顿力学方法建立了自旋弹头的姿态运动模型。选取质量块的运动方式为正弦运动,推导了质量块的运动加速度。为了分析质量块运动对自旋弹头姿态运动的影响,构建了仿真模型,选取质量块的三种不同运动频率进行了对比仿真。仿真结果表明,质量块的运动频率越大,即其运动加速度越大,引起的自旋弹头俯仰角和偏航角的变化范围越大,自旋弹头的机动能力越大。In order to express clearly and directly the relationship between controlled variables and attitude motion of a spinning warhead, the Newton dynamics method is applied to construct its attitude motion model. The moving mode of a mass is chosen as a sine movement. The acceleration of the mass is deduced. In order to analyze the effect of the mass＇ s movement on attitude motion of a spinning warhead, a simulation model is constructed. The simulation is performed by choosing three different frequencies of the mass. The simulation results show that the frequency of the mass is bigger, namely, its acceleration is bigger, the evocable varying ranges of its pitch angle and yaw angle are bigger; accordingly its maneuvering ability is bigger.
