The pressure distribution of a short journal bearing in dynamic loading conditions under the effect of forced harmonic excitation was investigated. The conventional form of the Reynolds equation was analysed numerically using the central finite difference technique with appropriate initial and boundary conditions. These numerical equations were written in FORTRAN-95 to obtain relevant results. According to the results, maximum oil pressure is obtained when external forced harmonic vibration is increased, giving a 51.92 percent increase over that obtained under self-excitation only.
