摘　　要：基于模型试验,对大深度浮力驱动式水下运载器的上浮运动进行研究与分析,基于数值仿真,提出大深度浮力驱动式水下运载器浮潜运动的快速预报方法,并将预报结果与模型试验结果进行对比,证明快速预报方法的准确性。使用快速预报方法,针对水下运载器比重变化、流体密度变化、水下运载器初速度以及水流扰动4种因素对浮潜运动的影响进行研究.此外,对水下运载器作六自由度运动时所受的水动力进行计算,为后续的六自由度运动预报和研究提供基础。The deep-water buoyancy-driven vehicle is crucial to the development and exploration of deep-sea,study on the phenomenon of floating and diving is important to ensure that the vehicle can successfully bereleased and recovered, and can work under water Based on model experiments, the paper studies and analyzesthe floating process of the deep-water buoyancy-driven vehicle. Based on the numerical simulation, # putsforward the fast prediction method for the deep-water buoyancy-driven vehicle＇s motion prediction of floatingand diving, and compares its prediction result to that worked out by experiment. The accuracy of the fastprediction method is verified Using the fast prediction method, it analyzes the influence of the proportion ofvehicle, the change of fluid density, the initial speed of vehicle and the disturbance of flow on the floating anddiving of deep-water buoyancy-driven vehicle. Beside5, it calculates the hydrodynamic forces in 6-DOF motion,which provides a basis for further motion prediction and research.
