水动力性能是载人潜器的关键技术指标，特别是在总体设计阶段针对载人潜器进行水动力计算具有重要意义。研究了数值计算的方法，选取长细比为6：1 的椭球体为研究对象，开展了网格划分方式的研究，得出了计算结果，并将计算结果与实验值进行了对比。对比结果表明，该方法具有一定的精度，验证了数值计算方法的可行性。选取几个典型工况，针对轻载作业型载人潜水器水动力进行数值预报，得出了相关的水动力系数，为该载人潜器的总体设计提供了理论依据。
The hydrodynamic performance is one of the key technical indicator of human occupied vehicle (HOV), and hydrodynamic calculation is significant especially at the overall design stage. This paper studies the calculation method of the hydrodynamic performance of HOV. Ellipsoids with a slenderness ratio of 6:1 were selected as the study subject, and the way of meshing was studied. The calculation results were obtained and compared with the tested results, which showed that the method is fairly accurate, verifying the feasibility of the calculation method. Finally, several typical working conditions were selected to estimate the hydrodynamic performance of light load HOV. The related hydrodynamic coefficients were obtained, providing theoretical basis for the overall design of the HOV.
