水下大型搭载平台与微小型机器人的干扰性能研究

摘要

Hydrodynamic interaction performance between a large underwater carrier and a mini-un-derwater vehicle was described using computational fluid dynamics technique (CFD). As an attempt in investigating the feasibility of a large underwater carrier carrying a mini-underwater vehicle, the in-teraction between two-dimensional object and wall was studied. Based on the unstructured mesh, the lift, drag and pitching moment performance were calculated when the distance between the mini-un-derwater vehicle and the large underwater carrier and the flow velocity were changed. The velocity and pressure distribution contours of longitudinal section in center plane were analyzed.%　　文章采用CFD技术计算大型水下搭载平台与微小型水下机器人之间的水动力干扰性能。作为对水下搭载的可行性的验证，研究了二维物体和壁面的干扰，进而计算了在不同来流速度和距离时的阻力、升力和倾覆力矩性能。同时计算了大型搭载平台与微小型机器人在不同来流速度和不同距离改变时的阻力、升力和倾覆力矩性能。此外，对微小型水下机器人的中纵剖面的压力和速度分布进行了细致的分析。
