| 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。

| Abstract: | 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.Th... |
