摇荡的形式 船舶的摇荡主要有下列六种形式:(1)横摇--绕船舶纵轴的往复摇动;(2)纵摇--绕船舶横轴的往复摇动;(3)首摇--绕船舶垂直轴的往复摇动;(4)垂荡--沿船舶垂直轴的上下往复运动,又称升沉;(5)横荡--沿船舶横轴的左右往复运动;(6)纵荡--沿船舶纵轴的前后往复运动。其中,横摇、纵摇和垂荡对船舶航行的影响最大,而横摇又最易发生,摇荡幅值也最大,严重影响船舶安全。
并且进一步计算船舶的垂向和横向加速度以及摇荡运动的统计特性。
Finally the vertical and transverse accelerations and the statistic characteristics of the vessel swing are calculated.
而船舶的各种摇荡运动中,横摇运动对船舶的危害最大。
In various ship swing motion, roll motion is the most serious and destructive.
船舶横摇运动是构成对船舶安全威胁最为危险的摇荡运动,它是导致船舶倾覆的最主要原因。
It is well known that, as ship roll motion is the most important reason which leads to ship capsizes, it is the most dangerous threat to the safety of ship.
