研究表明:在某些頻率范圍內相關水動力系數基本不隨吃水變化,只有超過某一頻率后水動力系數的值才會出現差異;在橫搖方向,水動力系數並沒有隨著吃水的變化發生規則變化,而是出現了波動現象;近船首剖面的水動力系數計算表明,水動力系數的波動非常大,並遠遠偏離了平均位置的水動力系數值,值的變化速率也不盡相同,總的看來,上振幅曲線曲率較大,變化較快,下振幅曲線曲率較小,變化較慢;外飄力和波面運動的速度的平方項有關,導致其振動頻率和相應運動方向的頻率不同;外飄力使升沉向下運動的幅值減小;船速對三個計算量的峰值影響甚微,但對振動頻率有明顯影響;波幅對船舶運動的影響是明顯的,船舶運動的幅值基本上和波幅成線性關系。It was pointed out that the actual center - line and theoretic meshing line of the paired gears varied in the form of planar motion due to the system vibration, and the actual meshing line was curvilinear
