摘要
针对水下航行体近海底航行时的特点,首先建立了水下航行体的操纵运动数学模型,分别从水平面和垂直面两方面来考虑近海底对操纵运动水动力的影响,进而数值模拟和分析了水下航行体在近海底运动时的操纵性能变化规律,计算结果表明近海底航行使得其机动性减弱而运动稳定性增强。
Based on the characteristics of underwater vehicle motion near sea bottom, a mathematical model of maneuvering motion for underwater vehicle is proposed. The influence of sea bottom on the maneuvering hydrodynamic forces of underwater vehicle is analyzed. A numerical simulation method is applied to an underwater vehicle＇s maneuvering motion when it moving near sea bottom. The calculation resuits indicates that the sea bottom has great influence on the maneuverability of underwater vehicle.
