摘　　要：针对船舶轴系应快速通过已设定转速禁区这一船级社规范要求,以及部分船级社就此进一步要求提供转速禁区通过时间的许用值并于试航中不同工况下测量予以验证的审图意见,运用材料疲劳的相关理论分析相关规范要求及审图意见提出的技术背景,随后结合对具体项目转速禁区通过时间计算许用值与试航实测值的对比、分析,就相关的轴系设计及试航实测数据的分析、处理给出建议。In light of that the rule requirement that barred speed range for marine shafting shall be rapidly passed,and further comment from a certain classification society that permitted time for passing the barred speed range shall be stated and proved during sea trial,the technical background for such requirement and comment were analyzed by fatigue theory for material.Combined with comparison and analysis of the calculated permitted time and the measured time during sea trial for passing the barred speed range in specified project,some suggestions were proposed regarding marine shafting line design and process of the calculated permitted time and measured time.
