The basic theory of the Finite Element Method is presented in detail. According to the practice of the propulsion shaft alignment,some improvements are made in the stiffness matrix due to taking the shear deformation effect into consideration. Based on the presented algorithm,the propulsion shaft alignment calculation program is developed in VB.NET language. By comparing calculation results with the output of other similar software without considering the shear deformation effect and the application in practice,it is proved that these improvements in the Finite Element Method are reasonable and can obtain more accurate results. The user-friendly interfaces,perfect functions and simple operations are included in the software,which meets the need of the checkout of the marine propulsion shaft and consummates the propulsion shaft alignment calculation model. It is convenient for the further redevelopment and study.
