摘要
文中深入研究了大深度动基座发射雷弹在海流作用下和发射过程中各组成部分的运动状态和动力学关系.分别建立了大深度发射雷弹动力学系统各组成部分的运动学和动力学数学模型:锚索动力学系统、发射平台开盖运动系统和发射运动系统的数学模型,同时给出了各分系统之间的相互关系。最后的算例表明开盖过程对雷弹离开发射平台口时刻的各种参数具有明显的影响,海流的作用将会引起发射平台发射前初始姿态和位置的改变.
We research into the locomotive state and the connection on kinetics that the system of a mine launching by a active exhaust in deep-water is moved because of the force produced by an undercurrent and the mine launch.On the basic we establish the following kinematic and kinetic mathematic model on the dynamic system of a mine in deep-water. They are the mathematic models of the dynamic system of an anchor cable and of the kinematic system on opening a cov- er and of the kinematic system on launch.And then we provide a method how to deal with the interrelation among the systems.The example shows that the parameters when the mine departs from the exhaust are obviously varied because of opening the cover.And the example shows that the first stance and location of the exhaust are varied because of the force of an undercurrent.
