摘要/Abstract

摘要： According to the analysis of the problems about the operation of marine propulsion shafting in steady
state, the geometric and mechanical coupling relationships between marine propulsion shafting and oil film of
bearings in two-dimensional space are established, and a coupling mathematical model of the marine propulsion
shafting in steady operating state is proposed. Then the simulation of a real ship is carried out, and the variation
laws of some special parameters such as bearing load and deflection are obtained. Finally, the results of simulation
are verified by experimental data of a real ship, which can provide the mathematical model and analysis method
for the research on the characteristics of ship propulsion shafting condition in steady state.
