由于潜器运动方程中水动力系数对潜器运动操纵性参数的影响程度各不相同,为确定流体动力布局中的各因素对操纵规律的影响程度,简化操纵运动方程。通过引入水动力敏感性指数S,量化水动力系数和操纵运动参数间的关系,以潜器六自由度方程中各水动力系数为研究对象,求出各水动力系数敏感性指数。结果表明:(角)速度系数和舵角系数敏感性较大,在设计阶段需重点考虑流体动力布局对其参数的影响且在求取其水动力系数时需保证其精度。本文研究成果可为潜器的设计和操纵运动方程的简化提供理论支撑。
Due to the influence of hydrodynamic coefficients on the maneuverability parameters is different in the motion equation of the submersible, in order to determine the influence of various factors in the hydrodynamic layout on the maneuverability, the motion equation is simplified. By introducing the hydrodynamic sensitivity index S, the relationship between hydrodynamic coefficients and maneuvering parameters is quantified, and the sensitivity indexes of hydrodynamic coefficients in the six degree of freedom equation are obtained. The results show that: the (angular) velocity coefficients are sensitive, so the influence of hydrodynamic layout on the parameters should be considered in the design stage, and the accuracy of the hydrodynamic coefficient should be guaranteed .It provides theoretical support for the design of the submersible and the simplification of the motion equation.
