| 摘 要： | 为了研究不同单点系泊位置对极地系泊船舶在来冰角度改变时动态响应的影响,运用离散元方法(DEM),计算了船舶在60%密集度下,冰速为1.0 m/s、冰厚为1 m时不同角度的船冰阻力,结合系泊分析软件二次开发功能,计算分析系泊船舶在不同来冰角度和不同系泊位置下受上述冰情影响下的响应。通过对模拟结果与试验结果的对比,认为离散元方法(DEM)的数值模拟结果与试验结果吻合较好;单点系泊位置为距船头L/4时,系泊船舶能以最快速、最稳定的方式对来冰方向的变化做出响应。

| Abstract: | With the continuous depletion of oil and gas resources in the land, many countries have gradually realized that the polar region may be another fertile land with abundant oil and gas resources. In order to study the influence of the different single point mooring positions on the dynamic response of ships when the intruding angle of ice floes changes, the Discrete Element Method was used to calculate the ship ice resistance with 60% ice concentration,1.0 m/s ice speed and 1.0m ice thickness. Using the secondary development function of mooring analysis software, the dynamic response of single point mooring ship was calculated and analyzed with five different mooring positions under the influence of the aforementioned ice conditions. Through comparative analysis, it is concluded that the numerical simulation results of Discrete Element Method can be well matched with the experimental results. When the mooring position is on L/4 from the bow, the moored ship can respond to changes in the intruding angle of ice floes in the fastest and most stable way. |
