摘要: 为分析外挂鱼雷武器后无人水下航行器的稳定性，首先确定了鱼雷的外挂位置，建立了无人水下航行器外挂鱼雷的运动模型，并将模型简化为纵向运动和横向-横滚运动。在详细分析了鱼雷对无人水下航行器作用力的基础上，建立了扰动方程并进行了拉氏变化，根据稳定性判据获得了无人水下航行器外挂鱼雷稳定性判断的条件。

Abstract: To analyze the stability of unmanned underwater vehicle (UUV) with external torpedoes,this paper calculates the optimum location of external torpedoes, deduces a spatial motion model of the hung torpedoes, and then simplifies the model as longitudinal motion and transverse rolling. Disturbance equation is achieved, and the Laplace transform is performed by analyzing the reaction force imposed on UUV by the external torpedoes. The condition to estimate the stability of UUV with external torpedoes is finally obtained according to the stability criterion.
