摘要
传统无控火箭上浮水雷容易受到各种扰动影响,导致上浮弹道散布较大;基于水下六自由度刚体运动学模型,分析了初始条件与上浮过程扰动等主要影响因素,建立了含扰动的上浮弹道数学模型,并通过数值仿真计算,分析了上述因素对上浮弹道出水点偏移的影响程度,为工程实际解决上浮弹道散布问题提供参考。
The traditional uncontrolled rocket-boosted mine is easily exposed to kinds of disturbances and as a result, a considerable rising trajectory distribution is brought about. Based on the underwater six de- gree-of-freedom rigid kinematic model, this paper gives an analysis of the main accountancies for distribu- tion of the uncontrolled rising trajectory including initial conditions and disturbances of the rising process. Then, a mathematical model with disturbances considered is established. With simulation given and deeply looking into the influences to the uncontrolled rising trajectory caused by those factors, we hope to offer some help in practical projects.
