潜艇外挂武器模块后的运动建模与仿真

摘要

为了对潜艇外挂武器模块后的运动性能进行研究,本文用近似估算的方法推算外挂后潜艇的水动力系数,建立六自由度运动的Matlab数学模型,并对潜艇外挂武器模块前后的5种典型运动进行对比仿真分析.仿真结果表明外挂武器模块对潜艇的运动性能有一定的影响,外挂后潜艇的操纵性降低、应舵性下降,所建立的仿真模型可基本反映潜艇外挂武器模块后的运动特性,可为下一步潜艇外挂武器模块论证奠定一定的理论基础.%To research the motion performance of submarines carrying external weapons module,this paper uses a way of estimation to calculate the hydrodynamic coefficients of submarines with weapons module,build the Matlab mathematical model of 6D motion,and do comparative simulation analysis of 5 kinds of typical motion of submarines carrying external weapons module before and after.The result of simulation indicates that carrying external weapons module has an effect on a submarine's motion performance to some extent,causing its maneuverability and steering quality to reduce.The simulated model can reflect motion features of submarines with external weapons module,which may provide theoretical foundation for further feasibility analysis.
