摘　　要：横摇是系泊船舶运动的主要形式之一,波浪和船舶装载条件是重要的影响因素。该文选取一艘10万吨级散货船进行系泊模型试验,在同一装载度下变化波浪和配载条件(入射波浪周期和船舶横摇固有周期),通过系列试验,分析了波浪周期和船舶横摇固有周期对系泊船舶横摇运动幅值和横摇运动周期的影响。研究结果表明,对于不同的船舶横摇固有周期,当波浪谱峰周期与横摇固有周期接近时,系泊船舶横摇运动均出现了一次峰值,并且横摇固有周期越小,波浪周期变化过程中的系泊船舶横摇峰值越大。系泊船舶横摇运动周期既和横摇固有周期有关,又和波浪周期有关,系泊船舶横摇运动相对周期(横摇运动周期/波浪谱峰周期)随着波浪相对周期(波浪谱峰周期/横摇固有周期)的增大而减小,并随波浪相对周期的增大而变化趋缓。The roll motion is the main form of the motion of a moored ship,which is significantly affected by the wave and loading conditions.In this paper,the mooring model test is performed with a 100000 ton cargo ship,and the effect of the wave period and the natural period on the roll motion of a moored ship is analyzed according to the results of series of model tests.The test results show that when the wave period is close to the natural roll period,the peak value of the roll motion amplitude of the moored ship occurs for different natural roll periods,and the peak value of the roll motion amplitude increase with the natural roll period decreasing.The period of the roll motion is dependent both on the natural roll period and the wave period,and the relative period of the roll motion（ratio of the roll motion period to the wave period） decreases with the relative wave period（ratio of the wave period to the natural roll period） increasing,and the change turns to be smaller.
