Originální abstrakt

The paper presents fast and robust algorithm for solution of body dynamics, fluid mechanics and tribology of flexible bodies subjected to sliding contacts. Moreover, it incorporates real physical influences such as contacts of surface roughness, elastic deformations, or the influence of surface roughness on bearing lubrication. Also a theoretical description of the physical problems and corresponding numerical solutions are presented. Finite difference method for Reynolds differential equation discretization, finite element method for calculation of elastic deformations, Gauss-Seidel method for iterative solution of discretized equations, original and modified Newton-Raphson methods or Newmark’s algorithm are the methods employed in the proposed solution approach. The coupled structural-fluid solver considering mixed lubrication conditions of the sliding contacts and nonlinear force equilibrium solver are the results. The proposed algorithms are compared with historically proven less advanced approaches on the example of a highly loaded slide bearing of a turbocharged compression ignition engine.
