摘　　要：鱼雷航行时受力复杂,是一个强耦合、非线性对象。依据动量和动量矩定理推导了鱼雷动力学方程,结合运动学方程建立了鱼雷空间运动的非线性数学模型。利用MATLAB/6.5simulink仿真平台实现了鱼雷航行的模块化仿真,模块化仿真模型通用性强,参数易于修改,使用方便。仿真结果验证了模型的正确性和有效性,为控制系统的设计提供了基础。Torpedo is a highly coupled and nonlinear object because forces acting on it are complex when navigating. Dynamics model of torpedo was derived according to momentum theorem combined with kinematics theorem to establish nonlinear equations of torpedo moving in space. Using the environment of MATLAB6.5/Simulink, a modularization simulation of torpedo was implemented. The modularization simulation model has the following properties, such as strong universal, parameters easily to be amended, and convenience to use. Results of simulation validate the feasibility of model, which provides foundation to design control system.
