Viscoelastic unsteady lubrication of radial slide journal bearing at impulsive motion

This paper presents an analytical solution of velocity components of unsymmetrical oilflow and pressure distribution in radial journal bearing gap for hydrodynamic unsteadylubrication with viscoelastic oil. Numerical calculations are performed in Mathcad 11Professional Program, with taking into account the method of finite differences. This me-thod satisfies stability conditions of numerical solutions of partial differential equationsand values of capacity forces occurring in cylindrical bearings. Exact calculations of pressure in journal bearing and its load capacity may be useful to prevent from prematurewear tribological units of self ignition engines, especially those applied in ships
