大深度潜器潜浮运动的建模与仿真(英文)

Simulation of the Descent/Ascent Motion of a Deep Manned Submersible

大深度潜器潜浮运动是一种超大攻角运动,它无法用常规水中物体的运动数学模型描述。文章给出了一种新型数学模型来描述这种大深度潜器的潜浮运动,并论述了结合现代仿真技术的应用,使潜水器所受流体动力的数学描述变得便捷、可行。此外,文中还研究了在大深度环境下,潜器潜浮运动时,潜器所受浮力和重力随深度变化的数学描述。上述理论已应用于有关潜器潜浮运动系统的设计。

The powerless descent/ascent motion of a deep manned submersible is an ultra-large attack angle motion.This motion cannot be described properly through traditional ,notion model for underwater bodies.In this paper,a new mathematical model is presented to describe this kind of deep manned submersible＇s descent/ascent motion.Modern simulation technique is used to present the motion model,which can make it easy and convenient to present the mathematical expression of sub- mersible＇s hydrodynamic forces.The variation of the buoyancy and weight of the deep manned submersible with depth is also considered.The method and theory presented in the paper were applied to the design of a practical deep manned submersible.
