Abstract: A comparative study of pressure distribution and load capacity of a cylindrical bore journal bearing is presented in this paper. In calculating the pressure distribution and load capacity of a journal bearing, isothermal analysis was carried out. Using both analytical method and finite element method, pressure distribution in the bearing was calculated. Moreover, the effects of variations in operating variables such as eccentricity ratio and shaft speed on the load capacity of the bearing were calculated. The analytical results and finite element results were compared. In order to check the validity, these results were also compared with the available published results. In comparison with the published results, generally finite element results showed better agreement than analytical results.
Keywords:Analytical Method, Finite Element Method, Journal Bearing, Load Capacity, Pressure Distribution.
