摘　　要：潜艇承载力是指抵抗静力载荷的能力,同时也是其动力抗沉能力大小的一个侧面。采用潜艇垂直面操纵性运动方程,考虑潜艇纵向水动力的平衡,将螺旋桨推力分解成系泊状态的推力和相对系泊状态减少的推力,导出潜艇承载力计算的动力学方程和承载力平衡方程。然后基于承载力平衡方程,提出潜艇极限承载力的4个衡准,并导出衡准参数的计算解析表达式。计算分析表明:螺旋桨是衡量潜艇承载力的重要因素,衡准参数能清晰地表征潜艇极限承载能力的大小,衡准参数的解析表达式可为承载力设计提供依据。The carrying capacity of submarines is the ability to resist static load, which serves as an important factor in judging the submarine＆#39;s dynamic unsinkability. Based on the vertical maneuverability motion equation and the longitudinal hydrodynamic force balance, the propeller thrust force is divided into the mooring portion and the relative decreased force on mooring state. Meanwhile, the dynamic motion equation of carrying capacity and the balance equation of carrying capacity are derived. Four criterion and the corresponding analytic expressions about the carrying capacity are presented based on the derived balance equation. Calculation and analysis show that the propeller plays a significant role to the carrying capacity, and the criterion presented in this paper could clearly evaluate the carrying capacity, and its analytic expressions provide the basis for future carrying capacity design.
