摘　　要：为提高半潜运输船甲板空间利用率,研究随机波浪线性化方法与附加阻尼比方法对半潜运输船外伸柱式结构物运输工况评估的影响。基于数值模拟与模型试验结果,对比两种方法在拟合横摇响应幅值算子(Response Amplitude Operator,RAO)中的局限性,对比两种方法对不规则波响应分析的影响,对比两种方法对外伸柱式结构物的气隙与波浪砰击评估的影响。结果表明:在横摇阻尼对比中,两种方法均具有局限性;在不规则波响应对比中,在单边幅值超过7°后,附加阻尼比方法得到更大的横摇响应;在气隙与波浪砰击评估中,附加阻尼比方法得到更大的横摇响应。在评估半潜运输船外伸柱式结构物的气隙与波浪砰击时,需要合理地选择横摇阻尼评估方法,以得到合理的横摇响应。In order to improve the utilization rate of deck space of semi-submersible ship,the influence of random wave linearization method and additional damping ratio method on the evaluation of transport operation condition of overhanging column structure of semi-submersible transport ship is studied.Based on the results of numerical simulation and model test,the limitations of the two methods in the fitting of roll Response Amplitude Operator(RAO)are compared,the influence of the two methods on the analysis of irregular wave response are compared,and the influence of the two methods on the evaluation of air gap and wave slamming of overhanging column structure are compared.The results show that:in the comparison of roll damping,both the two methods are of limitations;in the comparison of irregular wave response,after the single-sided amplitude exceeds 7°,the additional damping ratio method results in larger roll response;in the evaluation of air gap and wave slamming,the additional damping ratio method results in larger roll response.When evaluating the air gap and wave slamming of overhanging column structure of semi-submersible ship,it is necessary to select the roll damping evaluation method reasonably to obtain the reasonable roll response.
