Maxsurf Motions模块在船舶耐波性上的应用与验证

Application and Verification of Maxsurf Motions Module in Ship Seakeeping

船舶作为海洋中最主要的运动物体,其在海浪中的运动问题,是船舶适航性、耐波性的基础,同时也是船舶设计建造中的关键步骤。采用Maxsurf Motions模块对4种国际标准船模进行了耐波性计算,验证了Maxsurf Motions中的切片理论和面元法的计算精度与可靠性,探讨了Motions程序在船舶耐波性分析中的可行性,分析了Motions模块计算误差的原因。结果表明:Motions模块对船舶运动响应以及波浪增阻的计算精度基本令人满意。对于附加质量系数和阻尼系数,Motions在中高频波段的计算精度较高。研究成果对Maxsurf Motions的应用起到一定的借鉴和指导作用,同时也提供了一系列耐波性计算的验证算例。

The ship motion in the waves is the basis of the seaworthiness and seakeeping,and also the key step in the ship design and construction.Maxsurf Motions module was used to calculate the seakeeping of four international standard ship models,verified the calculation accuracy and reliability of the strip theory and panel method in Maxsurf Motions,discussed the feasibility of Motions program in ship seakeeping analysis,and analyzed the reasons for the calculation error of Motions module.The results show that the calculation accuracy of Motions module for ship motion response and wave drag is basically satisfactory.For the additional mass coefficient and damping coefficient,the calculation accuracy of Motions in the medium and high frequency band is high.The research results provide some reference and guidance for the application of Maxsurf Motions,and also provide a series of verification examples for seakeeping calculation.
