A comprehensive method of thermoelastohydrodynamic (TEHD) lubrication analysis for dynamically loaded journal bearings is presented. The Reynolds equation in the film is solved using the Finite Element (FEM) discretization. Thermal distortions as well as the elastic deformation of the bearing surfaces are computed using FEM method. The lubrication film temperature is treated as a time-dependent three-dimensional variable with a parabolic variation with respect to the film thickness. In order to compute the film and solid temperature, a new heat flux conservation algorithm is proposed. Fourier series approximate the instantaneous temperature fields in the solid boundary layers. Solving the complex problem of big end connecting rod bearing TEHD lubrication proves the algorithm efficiency.
