摘要：

Wave Glider (WG) is a new type of wave-powered marine vehicle with a strong coupling multi-body system, and there are no unified and proprietary methods hitherto for dynamic modelling of the WG system. Combining the advantages of the existing models, this paper proposes new dynamic modelling for the WG system, including the Length-Fixed Cable Model(LFCM) and the Length-Variable Cable Method(LVCM), which are proved to perform similarly and have good accuracy under ideal conditions compared with previous works. Furthermore, this paper provides a simulation in four different ratios of thrust to wave force, and the conclusion can be used as a supplement for some authors who claim that the thrust is much larger than the wave force on the surface floater without a boundary.
