The invention discloses an amphibious vehicle with an underwater sailing drag reduction mechanism and a design method of the amphibious vehicle, and relates to the technical field of amphibious vehicles. The design method of the amphibious vehicle comprises the steps that an amphibious vehicle CFD model is constructed, and model boundary conditions are set for the amphibious vehicle CFD model; performing numerical simulation of the amphibious vehicle to obtain numerical simulation results of the amphibious vehicle at different speeds; analyzing according to the numerical simulation results of the amphibious vehicle at different speeds to obtain the flow state of the rear edge of the bottom of the amphibious vehicle; on the basis of amphibious advancing environment conditions of the amphibious vehicle and the flowing state of the rear edge of the bottom of the amphibious vehicle, a retractable tail wing is installed at the tail of a vehicle shell of the amphibious vehicle. According to the amphibious vehicle designed by the invention, the resistance during sailing in water is reduced, transverse and longitudinal swinging is reduced, and the newly added structure does not affect the trafficability of the amphibious vehicle when the amphibious vehicle runs on the land. According to the design method, through accurate numerical simulation, comprehensive fluid characteristic analysis and targeted optimization steps, the design efficiency, precision and flexibility are improved.
本发明公开了一种具有水中航行减阻机构的水陆两栖车及其设计方法,涉及水陆两栖车技术领域。水陆两栖车的设计方法包括:构建两栖车CFD模型,并为其设置模型边界条件;进行两栖车数值模拟,得到不同速度下两栖车数值模拟结果;根据不同速度下两栖车数值模拟结果分析得到两栖车底部后缘的流动状态;基于两栖车的水陆两栖前行环境条件,以及两栖车底部后缘的流动状态,在两栖车的车壳尾部安装可收放的尾翼。本发明设计的水陆两栖车,降低了水中航行时的阻力,减少了横向和纵向的摆动,且新增结构也不会影响两栖车在陆地上行驶时的通过性。本设计方法通过精确的数值模拟、全面的流体特性分析和针对性的优化步骤,提高了设计效率、精度和灵活性。
