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

摘要

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°, 180° grooves and asingle oil hole. Aided by the database, dynamically 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 Maxwellmodels. The solutions 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 neglected as compared to the latter cases.
