摘要
围绕现行的FSICR、RMRS和IACS三大冰区航行船舶规范,对船级符号、船体分区、总纵强度、低温材料等要求展开讨论.以重型破冰船为对象,对结构设计中的冰载荷计算,以及冰级、排水量、骨架形式、肋骨间距等设计参数的影响进行比较分析,为此类船型的结构设计提供技术参考.
Abstract
Based on the current structural rules of FSICR,RMRS and IACS,the requirements of classification notation,hull areas extent,longitudinal strength and structural material selection in low temperature environment were discussed.Taking a heavy icebreaker as the research object,the effect of ice load calculation and some principal characteristics such as ice class,dis-placement,frame system and spacing were comparative analyzed,in order to provide reference for the structural design of heavy icebreaker.
