摘要
双船在浅水中航行时,由于舰船与舰船之间及其引起的兴波相互叠加或干涉的影响,使得双船水压场特性与单船水压场特征有明显区别。通过实验研究发现,双船在低速和亚临界航速情况下航行时,舰船水压场负压峰值或负压持续时间会显著增大,对舰船航行安全造成不利的影响;在超临界航速纵向距离超过半个船长时,首舰水压场负压峰值显著减小,对首舰航行安全有利。
The character of hydrodynamic pressure field of two moving ships is different with that of single moving ship because of the influence of two moving ships and interaction of wave which caused by them. It is proved by experimental research that the peak value of minus pressure is enlarged or the sustained time of minus pressure is prolonged when two ships are moving at low speed or subcritical speed, that is adverse to two moving ships ; The peak value of minus pressure of first ship is reduced obviously when two ships are moving at supcritical speed and the longitudinal distance is more than half ship length.
