| Abstract: | 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. |
