Due to the large journal and long length, the installation of the stern shaft on the large ship is very difficult. In view of this situation, the numerical method based on three bending moments is used to analyze the number and arrangement position of temporary support during the installation of the stern shaft, to solve the change of the deflection and stress of the stern shaft and the reaction force of temporary support, and to obtain the influence law of the number and arrangement position of temporary support on the deflection and stress of the stern shaft. The calculation results show that when the stern shaft is pushed into the rear end face of the fore stern bearing, the deflection of the front end of the stern shaft is too large to pass the fore stern shaft tube bearing smoothly, so that a new technology of the guide shaft fixing at the front of the stern shaft was adopted, the structure, size and hoisting mode of the guide shaft were optimized, and the smooth installation of the long stern shaft was realized. The research results can provide a theoretical reference for the installation analysis and calculation of stern shaft section of large ships. Chinese library classification no. : U662.2
