摘　　要：针对高速两栖轮式车物理特征参数的变化对其静水航行阻力特性进行了研究分析.仿真计算分析表明:车体吃水线以下的结构线型、轮舱结构对水上航行阻力有一定的影响,尤其关键的航行阻力峰值影响较大;轮胎及整车重量对水上阻力影响也较为显著.因此提出:要实现两栖轮式车高航速性能,车体构型优化设计、轮胎收放、轻量化是需要重点突破的关键技术.In view of the change of physical characteristic parameters of high-speed amphibious wheeled vehicle,the static water resistance of the vehicle is studied and analyzed.The simulation results show that:the structure line below the water line and the wheel cabin structure have a certain impact on the water resistance,especially the key peak value of the navigation resistance;the tire and vehicle weight also have a significant impact on the water resistance.Therefore,it is proposed that in order to realize the high-speed performance of amphibious wheeled vehicle,the key technologies that need to be broken through are body configuration optimization design,tire retraction and release,and lightweightof body.
