The analyses and simplified solutions to predict dynamic performances of the multirecess hybrid-operating oil journal bearings were presented by one dimensional method. The linearized stiffness and damping coefficients of a typical capillary-compensated bearing with four recesses were computed for various design parameters,and corresponding stiffness and the stability threshold of the bearings were then obtained. After comparing the data got form the simplified solutions with those from the numerical solutions of Reynolds equation, this paper discusses the errors in the former solutions and proves that the results can meet engineering needs under the usual working conditions.
