Abstract
An approximate analytical solution of nonlinear oil film forces is proposed which is suitable for finite slider bearings. Based on some transformations on transient Reynolds equation, the limitation of Reason's hybrid approximate method is overcome and extended to be capable of being used in nonlinear dynamic analysis for rotor bearing systems. A typical rigid rotor bearing is employed to verify the effectiveness of the suggested method. The results show that even in case of high speed and big eccentricity, the obtained journal locus can agree well with that of numerical calculation.
