两栖车辆水上快速性设计研究

Research on Rapidity Design of Amphibious Vehicles

水上快速性是影响两栖车辆战场生存能力的重要因素,也衡量两栖车辆航行性能的重要指标之一。为了提高两栖车辆的水上快速性,通过减阻增速的途径,对两栖车辆的车轮收放装置进行了研究,并通过数值模拟的方法对车轮收起后的减阻效果进行了分析,结果表明,车轮收起后,两栖车辆的水上行驶阻力减小,增速效果明显,是减小两栖车辆水中行驶阻力的有效方法。本研究是对我国高速轮式两栖车辆在改进设计和性能分析方面的一项有益探索,为我国两栖车辆相关技术的进步奠定基础。

The rapidity is an important factor to the survivability of amphibious vehicles,which is also an important index to value the navigation performance of amphibious vehicles. In order to improve the run-ning speed of amphibious vehicles on water,wheels retracted and deployed were researched by resistance reduction. Then drag-reduction effect of wheel retracted was calculated and analyzed by numerical simula-tion. The results show that water-resistance is reduced when wheels retracted. Therefore,wheels retracted and deployed is an effective way to reduce the running resistance of amphibious vehicles on water. In gen-eral ,the study of this paper is a beneficial exploration to the design and performance analysis of high-speed amphibious vehicles,which lays the foundation for amphibious vehicles related technologies.
