摘要：

应用CATIA曲面造型模块，设计出一款具有快速性特征的新型两栖车车体外形和一种新型防浪板。在FLUENT软件中应用VOF方法、标准k-ε湍流模型、明渠流和高速艇动力学相关理论,对未加装和加装防浪板的两种车辆模型进行了水上性能数值分析。研究结果表明：加装防浪板的车辆模型水上性能更优。该方法可有效应用于高速过渡型两栖车辆的水上性能研究。

Abstract:

A new type of amphibious vehicle body with fast features and a fresh style of wash plate were designed herein by using CATIA shape-design module. Numerical analysis for waterborne performance was carried out for two amphibious vehicle models:one with wash plate and the other without, using the VOF method,the standard turbulence models, open channel flow and the theory of high speed boat dynamics in Fluent. The results show that the model with wash plate is better in waterborne

performance and these methods can be applied effectively to high-speed transitional amphibious vehicle waterborne performance research.
