摘　　要：通过对比分析不同的潜艇运动方程,得到适用于潜艇水下回转运动仿真的数学模型,采用分段计算方法对潜艇水下回转运动横向水动力进行建模仿真。分析了潜艇水下定常回转运动仿真参数的变化规律,结果与实艇操纵具有较好的一致性,从而证明了本文所用潜艇数学模型和建模仿真方法正确有效。同时,本文也为下一步研究潜艇水下回转运动非线性特征打下基础。A mathematical model suitable for submarine underwater rotary movement simulation can be got by comparing and analyzing different submarine motion equations,then the yawing force model of submarine underwater rotary movement is made and the simulation is done in the software using subsection count algorithm.The mathematical model and algorithm are certified effective by the analyzing result which is in good accord with the parameters＇ law of actual submarine in steady rotary movement under water. At the same time,this paper lays a foundation for the nonlinear study of submarine underwater rotary movement in the future.
