摘　　要：在强机动条件下,水下航行器运动模型的解算可能会出现分岔、突变和多解等现象,对应于水下航行器的运动会出现失稳现象。针对这一问题,采用系统稳定性、稳定性判别及分岔等理论,以及解算高维非线性系统的延拓算法,研究了各项参数对水下航行器高速运动稳定性等非线性特性的影响,求出了产生分岔等危险情况的数值解。研究结果对水下航行器的实际操作控制可提供有益指导。Under the condition of strong maneuvering,the phenomena of bifurcation,saltation and multiple solutions mayoccur to the resolving of underwater vehicle motion model,corresponding to the motion of underwater vehicle,an unstable phe?nomenon may appear.To solve this problem,the influence of various parameters on the stability of underwater vehicle in highspeed is studied according to the theories of the system stability,stability identification and bifurcation,as well as continuationalgorithm for high?dimension nonlinear systems.The numerical solution of the bifurcation and other dangerous situations was ob?tained.The research results can provide a useful guidance for practical operation control of underwater vehicle.
