碩士 / 國立臺灣海洋大學 / 機械與機電工程學系 / 94 / This study provided an optimum searching method for designing the shafting system. The purpose was to avoid design errors which cause damages to the shafting system. This method utilized Computer-Aided Engineering (CAE) of the Finite Element Method to analyze strengths of the shafting system. It is a precise calculating method which can replace some traditional methods, such as three moment equation method. A simple shafting system model was used to study though three moment method and finite element method. After comparing two results, showed that the maximum deviation of reaction force is 6.84 %, and the minimum is 2.1 %. Computer-Aided Design (CAD) software was utilized to change the curve (offset of bearings) of the shafting system. Then the models were provided for CAE software to analyze individually. Finally, a set of optimum offset bearing positions were found. Comparing the outcome above-mentioned with the shipyard’s original design values, the maximum offset deviation was 0.44 millimeter on the crank shaft, and the minimum was 0.36 millimeter on the intermediate shaft. According to above results, the CAD and CAE optimum searching method has proved that its technical capability as design of shafting system for large merchant ships.
