| 摘 要： | 针对大型非自航绞吸挖泥船的防台问题,建立了绞吸挖泥船的水动力模型,采用准静力分析法和时域动力分析法分别计算不同工况下绞吸挖泥船的锚链波频张力和锚链最大张力。对比两种方法的计算结果,科学地评估绞吸挖泥船的系泊承载能力。结果显示,准静力分析法和时域动力分析法都可以较好地用于绞吸挖泥船系泊能力的计算,绞吸挖泥船所配备锚链和锚可满足15级台风下的防台定位需求,保证该锚泊定位安全。

| Abstract: | Aimed at the problem of typhoon resistance of large non-self-propelled cutter suction dredgers,the hydrodynamic model of cutter suction dredger is established.The quasi-static analysis method and time-domain dynamic analysis method are used to calculate the maximum wave force tension and the maximum tension of mooring line under different operating conditions respectively.Comparing the results of the two methods,the mooring capacity of the cutter suction dredger is evaluated scientifically.The results show that both the quasi-static analysis method and the time-domain dynamic analysis method can be well used in the calculation of mooring capacity.The mooring equipment can meet the needs of mooring positioning and ensure the security under the 15th typhoon. |
