摘 要:采用有限体积法与VOF方法,并结合重叠动网格技术对滑行艇模型进行数值模拟与验证。采用边界造波法对规则波进行了数值模拟并加以验证,结果表明数值模拟得到的波浪在波长、波高以及周期等主要波浪参数方面具有良好的精度。分别模拟了不同滑行速度以及不同浪向角情况下,水陆两栖飞机在波浪水面上的滑行过程,计算结果表明:飞机滑行速度越大,水动载荷的变化幅度越大,飞机垂向过载的最大值越大,飞机垂向位移和纵倾角的变化幅度越大,变化周期越长;飞机最好在尾斜浪或顺浪的状态下滑行,能够在一定程度上减小飞机垂向过载、垂向位移和纵倾角的波动。The finite volume method and VOF method combined with overlapping dynamic mesh technology are used for the numerical simulation of planing boat sliding on water. The defining inlet boundary wave generation method is used for the numerical simulation of regular wave. The verification result shows that the simulation of regular wave have good precision. The amphibious aircraft sliding on wave are simulated. The cases of different speeds and different wave direction angles are researched respectively. The hydrodynamic load, the vertical overload, the vertical displacement and the trim angle of amphibious aircraft were calculated. The calculation results show that the higher the amphibious aircraft’s speed, the larger the amplitude of hydrodynamic load, the larger the maximum value of vertical overload, the larger the amplitude of vertical displacement and trim angle. It is better for the amphibious aircraft to taxi under the condition of quartering wave or following wave, which can reduce the fluctuation of vertical overload, vertical displacement and trim angle of the amphibious aircraft.
