摘　　要：为研究阻流板对滑行艇阻力性能的影响,进行了不同阻流板深度下的滑行艇模型试验研究,并通过Star-CCM+软件平台对试验工况开展模拟,分析了阻流板的作用机制。结果表明:合适深度的阻流板能够有效的降低滑行艇的阻力和提高运动稳定性;与试验值相比,数值计算的中低速阻力误差小于5%,高速误差小于10%;阻流板减阻的主要原因是改变了艇底的压力分布,降低了航行纵倾角。In order to study the effects of the interceptor on the resistance performance of planning hull,the experimental study on the model of different depth of interceptor was carried out,the test conditions were simulated by Star-CCM+software platform,the operating mechanism of the interceptor on the hydrodynamic characteristics were analyzed.The experimental and numerical results showed that:suitable depth of interceptor can get better resistance and stability qualities;compared with the test value,the resistance error of medium and low speed is less than 5%and that of high speed is less than 10%;The resistance reduction by interceptor was due to the change of the pressure distribution of the bottom and a decrease of dynamic trim.
