This report describes an analysis of the jounal bearing under dynamic load taking into account bearing deformation and journal tilt in comparison with measurement of a marine diesel engine. The bearing characteristic is calculated using the finite difference method on 2-D Reynolds equation. The bearing load and journal tilt are calculated using the load of all cylinders, and the bearing deformation is derived considering not only the bearing housing but also the construction of engine body. The stiffness of crankshaft and engine body is calculated using the finite-element method. Generally good agreement is obtained for the bearing deformation, the journal tilt and minimum film thickness, between predicted and measured results.
