Original abstract
This paper presents computational approaches for verification of conceptual study of low-friction-losses crank train design and its vibration analysis. The decrease of friction losses is realized by reduction of crankshaft main bearings number while the influence of a crankshaft pulley torsional vibration and main bearings load are investigated. The computational model is assembled as well as numerically solved in a Multi-Body System whereas the modally reduced bodies are incorporated into it and hydrodynamic problem is also taken into account.

Tento příspěvek popisuje moderní výpočtové metody pro ověření koncepční studie klikového mechanismu s nízkými třecími ztrátami a analysu jeho kmitání. Snížení třecích ztrát je dosaženo snížením počtu hlavních ložisek klikového hřídele, přičemž se sleduje vliv na torsní kmitání řemenice klikového hřídele a zatížení hlavních ložisek. Výpočtový model zahrnuje modálně redukovaná pružná tělesa, hydrodynamická ložiska a je sestaven i numericky řešen v prostředí Multi-Body System.
