摘　　要：应用非线性系统运动稳定性理论和同伦算法,分析潜艇水下高速直航的运动稳定性,并通过其非线性运动方程数值积分的动态仿真进行验证,仿真试验表明稳定性分析结果正确。从而说明本文提出的采用非线性系统运动稳定性理论和同伦算法来分析潜艇水下高速机动的运动稳定性方法有效。In this paper,the motion stability theory of nonlinear systems and the algorithm of homotopy techniques are applied to analyze the motion stability of submarines with straight high speed. The results of stability analysis are verified by simulations using direct numerical integrations of the nonlinear motion equations of submarine. It indicates that the motion stability theory of nonlinear systems and the homotopy algorithm could be effectively used to analyze the motion stability of high-speed submarines under water.
