摘要
为了分析尾部吊耳对船舶阻力的影响,进行阻力性能验证,采用非定常方法进行阻力模拟,分别对比尾部未安装吊耳与安装吊耳时的船体阻力.根据计算结果,未安装吊耳与安装吊耳的船体摩擦阻力偏差为0.12%,剩余阻力偏差为-0.37%,总阻力偏差为0.01%,此相对偏差均在工程应用的合理范围内,说明船体尾部安装吊耳对船体阻力性能基本无影响.
Abstract
In order to analyze the influence of the stern lifting lugs on the ship resistance and verify the resistance performance,the resistance simulation is carried out by using the non-stationary method,comparing the ship resistance when the lifting lugs are not installed at the stern with those when they are installed,respectively.According to the calculation results,the deviation of the hull friction resistance without lifting lugs installed and with lifting lugs installed is 0.12%,the deviation of the residual resistance is-0.37%,and the deviation of the total resistance is 0.01%,and this relative deviation is within the reasonable range of the engineering application,which indicates that the installation of lifting lugs at the stern of the hull basically has no effect on the resistance performance of the hull.
