Fast analysis of crankshaft bearings with a database including shear thinning and viscoelastic effects

Database consists of nondimensional data of load capacity, maximum pressure and its position, flow and power loss factors obtained by solving the full 2-D Reynolds equation including the effect of oil feed features of 360 deg rees, 180 degrees grooves and a single oil hole. Aided by the database, dyn amically loaded journal bearings are analyzed without solving the Reynolds equation. The database is interpolated linearly. The fluids shear thinning and elasticity are characterized by the power law and Maxwell models. The s olutions given by the present method are almost identical to the expensive FDM solution, and the CPU time consumed in the former cases almost can be n eglected as compared to the latter cases.
