- 摘要:
- 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 1 558 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.
