船舶阻力试验实船换算的蒙特卡罗仿真

Monte Carlo simulation for full-scale ship conversion of ship model resistance test

为了评判试验数据可信程度和提高试验质量,对基于1+K法的船舶阻力试验实船换算进行蒙特卡罗仿真。结果表明:随着实船速度的增加,实船阻力和实船有效功率的标准不确定度分别从455 N,1.42 kW逐步增加至1558 N,10.96 kW,实船阻力和实船有效功率的相对标准不确定度分别从1.56%,1.56%下降至0.44%,0.44%;实船阻力和实船有效功率的蒙特卡罗仿真值分布左右对称,符合正态分布。

In order to evaluate believable degree of test data,and improve test data quality,Monte Carlo simulation was made for full-scale ship conversion of ship model resistance test based on 1+K method.With full-scale ship velocity increasing,standard uncertainty of full-scale ship resistance and effective power of ship model resistance test increased from 455 N and 1.42 kW to 1558 N and 10.96 kW,relative standard uncertainty descended from 1.56%and 1.56%to 0.44%and 0.44%.Monte Carlo simulation value of full-scale ship resistance and effective power accorded with bilateral symmetry which is normal distribution.
