摘要
船舶在冰区破冰航行,当浮冰厚度和强度大于船舶的破冰能力时,须采用冲撞式破冰前进,船速和主机使用不当会造成船舶被冰卡住.通过船舶破冰受力分析,提出避免冰卡最大安全破冰船速的表达式,并在"雪龙"号南极破冰实船验证,其结果对破冰航行有重要意义.
The means of crush type icebreaking is normally used when the ice thickness and strength are greater than ship＇s ice breaking capacity.Any miscarriage of ship speed and main engine may lead the locking of icebreaker.Through analyzing the admitted weight on the ice sheet,the paper put forward the maximum security speed in the operation field,which has been verified by Chinese icebreaker ＂Xuelong＂ navigated in Antarctic.The results have important significance for icebreaking sailing.
