Original abstract
The chapter presents an approach for a solution of dynamics and tribology of slide bearings incorporating influences such as contacts of surface roughness, elastic deformations, or the influence of surface roughness on bearing lubrication. Finite difference method for Reynolds equation discretization, finite element method for calculation of elastic deformations, Gauss-Seidel method for iterative solution of discretized equations or Newmark’s algorithm are the methods employed in the proposed solution approach. The coupled structural-fluid solver considering mixed lubrication conditions of the slide bearing and force equilibrium solver are the results.
Czech abstract
Kapitola představuje přístup pro řešení dynamiky a tribologie kluzných ložisek včetně zahrnutí vlivů, jako jsou kontakty povrchových drsností, pružné deformace, nebo vlivy povrchových drsností na mazání ložisek. Metoda konečných diferencí je použita pro diskretizaci Reynoldsovy rovnice, metoda konečných prvků je použita pro výpočet elastických deformací a Gauss-Seidelova a Newmarkova metoda jsou použity pro iterativní řešení discretizovaných rovnic. Výsledky jsou tvořeny spojeným řešičem struktury kapalin, uvažujícím podmínky smíšeného mazání, a rovnováhy sil působících v kluzném ložisku.
