摘要
为了保证潜水器具有良好的操纵性能,构建操纵运动方程的水动力系数必须具有相当的准确性.文中以某长航程潜水器为研究对象求解其水动力系数,分别采用了近似公式估算、基于势流理论的面元法和提出的应用FLUENT模拟循环水槽试验3种方法.通过计算结果与模型循环水槽操纵性能试验结果的对比分析,总结了上述三种计算方法的适用范围和效果评价.
Hydrodynamic coefficients are coefficients of Automatic Underwater Vehicle(AUV) maneuver equations.Accurate coefficients are needed to satisfy the well-performed maneuverability.The research of the paper is based on a Long-Endurance AUV,its coefficients have been calculated by three kinds of method following: approximate formula method,surface panel method and new method-CFD software numerical simulation.All the calculated data are compared with experimental data and the applicability and precision of each method are given.
