For the calculation problem of steady load of bearing with dynamic response of oil film, a mixed solution method which includes analytic method and iterative method is proposed. A basic route of the mix solution and the sub modules is designed according to the coupling mathematical model of the steady load of ship shafting bearing. And MATLAB code is programmed and completed. Then, the convergence strategy,the iteration step, the criterion, the method of data transmission and so on are analyzed and the solutions are put forward. So a method of fast and accurate solution is achieved. Finally, the solution method is verified by experimental results.
