摘　　要：以某超高速两栖车辆为研究对象,其车体采用M型构型,针对其水上高速滑行状态,利用计算流体力学(CFD)开展水动力学特性分析研究,重点对流场、阻力特性、升沉特性、纵倾及其力矩等进行了研究.结果表明,车辆在航速35 km/h左右时阻力达到峰值,在航速50 km/h时完全处于滑行状态,且其升沉和纵倾特性表明,车辆在各航速下能够稳定航行.Taking the M-shaped body of an ultra high speed amphibious vehicle as the research object,the hydrodynamic characteristics of its high-speed gliding state on water were analyzed and studied using computational fluid dynamics(CFD).The focus of this study is on the flow field,resistance,heaving,pitching and its torque.The results show that the resistance of the vehicle reaches its peak at a speed of around 35 km/h,and it is completely in a coasting state at a speed of 50 km/h;And its heaving and pitching characteristics indicate that the vehicle can navigate steadily at various speeds.
