The present disclosure provides a lubrication analysis method for a stern bearing based on magnetic-hydraulic composite support coupling, including: performing structural deformation analysis on a stern bearing on the basis of a magnetic support analysis result and a lubrication support analysis result to obtain a structural deformation amount, correcting a water film thickness, repeating lubrication and interface characteristics analysis to obtain water film pressures before and after correcting, comparing the water film pressures to determine whether convergence occurs, solving for a load carrying capacity of the stern bearing on the basis of the analysis result if the convergence occurs, determining whether the load carrying capacity is balanced with an input load, and calculating a bearing wear depth of the stern bearing on the basis of a contact force of a micro-convex body if the load carrying capacity is balanced with the input load.
