摘　　要：随着两栖车辆水上航行速度逐渐向高航速发展,其水动力学特性由于具有自由面大变形、瞬态载荷以及湍流流动等复杂特征对流动特性的影响非常复杂。利用无网格模型、LBM计算方法对两栖车辆水动力学特征参数进行了数值仿真模拟,并与拖模实验结果对照。结果表明该数值仿真方法能够准确地给出复杂表面流场状态分布,与实验结果符合程度较高。As the speed of amphibious vehicles on water gradually is higher,the hydrodynamic characteristics of amphibious vehicles are very complicated due to the large deformation of free surface,transient load and turbulent flow.The parameters of amphibious vehicle hydrodynamics are simulated numerically by using meshless model and LBM method,and are compared with the results of the towing model experiment.The results show that the numerical simulation method can accurately present the state distribution of the complex surface flow field and is in good agreement with the experimental results.Based on this method,the paper further carries out multi-scheme surface water drag reduction analysis.
