    Calculation of stiffness and damping coefficients of hydrodynamic lemon-bore journal bearings

  • Original language description

    This paper deals with a calculation of stiffness and damping coefficients of the hydrodynamic lemon-bore journal bearings of the finite length. The hydrodynamic pressure distribution is described by the dynamic Reynolds equation solved using the finite volume method. The variable temperature in the circumferential and axial directions of the bearing is considered in the calculation resulting in changes of the lubricant viscosity and density. The proposed computational model involves the mixing of the lubricant, obtaining a steady-state solution of the pressure and temperature, and establishing the equilibrium position of the journal. Based on the small dynamic displacements of the journal from the equilibrium position, the stiffness and damping coefficients are determined. The results of these dynamic characteristics are presented in dependence on speed for the selected load of the particular lemon-bore bearing.
