无级变速鱼雷建模研究

Research on Modeling of Stepless Speed Torpedo

为了满足无级变速鱼雷性能分析和动态仿真的需要,本文针对无级变速鱼雷,在国际通用的坐标系下,建立了无级变速鱼雷的运动学方程,分析了作用在鱼雷上的所有外力,对无级变速螺旋桨推进器的特性进行了研究和建模,并基于经典的动量和动量矩定理,建立了无级变速鱼雷的动力学方程。本文所建的水动力学模型可用于无级变速鱼雷的操纵性分析和控制系统的仿真试验。该模型已与在非通用坐标下建立的模型进行了对比仿真试验,结果表明,二者具有很好的一致性。

For the performance analysis and the dynamic simulation of stepless speed torpedo, the kinematical equations for stepless speed torpedo on international universal coordinates are proposed, the external forces and moments acting on the torpedo are analysed, the property analysis and modeling of stepless speed propeller are conducted, and the kinetic equations are established based on the classic theory of momentum and momentum moment. The new hydrodynamic model proposed can be used in the torpedo＇s maneuver analysis and control system simulation. Contrastive simulation of the models on different coordinates was done, and the results show that both models have good consistency.
