变质量鱼雷的空间运动建模

Mass-varying Model for Torpedo

文中建立了一种矢量形式的变质量鱼雷六自由度(6DOF)运动数学模型。在现有的水下航行器的运动模型基础上,充分考虑了燃料消耗等原因对于鱼雷运动的影响。同时,采用矢量形式,使得所建立的方程形式简洁并易于数值计算与仿真的实现,对于变质量水下航行器的设计与分析工作具有重要的意义。

A mass-varying model for torpedo in 6 degrees of freedom(DOF)is derived.Contrary to current models for autonomous underwater vehicle(AUV),the variation of mass.centroid and moment of inertia because of fuel combus- tion is considered.The equations are described in vector-matrix form so that it could be expressed concisely and more ef- fectively for calculation and simulation.In addition,the rationality of the model is argued across a trajectory simulation for a mass-varying torpedo.The model provides foundation for mass-varying autonomous underwater vehicle(AUV)'s analyzing and designing.
