software

BearDyn in version 4.5 is a software tool for solving problems of dynamics and thermo-elastic-hydrodynamic plain bearings. Inputs are the properties of the oil, the reaction force in the sliding bearing, the relative angular velocity and the stiffness matrix of the pelvis and the pin. To solve the balance pin is used modified Newton method with an estimated Jacobian based Boyden method. The pressure in the oil layer is based on solving Reynolds equation by using the finite difference method with consideration of the influence of pressure, temperature and shear stresses on the viscosity and density of oil, the elastic deformation of the pin and pans, by unevenness on the oil flow and contact bumps. The software includes a preprocessor, solver and postprocessor. The solution of the kinematic quantities and deformation structures and tribological parameters describing mixed lubrication.
