摘　　要：两栖车辆的水动力构型研究正逐步由中低航速构型转向高航速构型设计。为解决两栖车高航速阻力大、兴波强烈等问题,提出M型超高速两栖车辆构型,并基于计算流体力学方法对该车型不同直航工况进行了数值分析。分析结果表明,该构型能够通过吸收首兴波提升车体整体水动升力并显著降低两栖车辆水上航行阻力,且通过合理的重心位置设计能达成较好的纵向稳定性。The research on the hydrodynamic configuration of amphibious vehicles is gradually shifting from low-speed configuration to high-speed configuration design.In order to solve the problems such as strong resistance and strong wave formation when the amphibious vehicle travels at high speed,a M-type ultra-high-speed amphibious vehicle configuration was proposed,and of different linear sailing conditions of this vehicle was analyzed.The analysis results show that the configuration can improve the overall hydrodynamic lift of the vehicle body by absorbing the wave,and significantly reduce the overall drag of amphibious vehicle.Besides,the vehicle can achieve better vertical stability through a reasonable center of gravity.
