Abstract
The propulsion shaft alignment affects the safe and reliable operation of the ship shaft system during its exploitation. Currently, there are many different methods used to compute the shafting alignment. The most popular method is the shafting alignment according to the bearing reaction using the finite element method. In the world, these software have appeared to compute shafting alignment, but they require very high costs. Therefore, in this study, the authors focus on building a program to compute the shaft alignment according to the bearing reaction using the finite element method. The specific ship's computation results are compared with the shipyard's results to validate the program's accuracy. This study is the primary step in developing domestic shaft alignment software.
