Original abstract
This paper presents a study of an influence of crankshaft counterweights size upon the engine block load. The engine block load is significantly affected by crank train inertia forces and moments mainly at higher engine speed. This load can be reduced by means of crankshaft counterweights and their appropriate design. The influence of counterweights design upon the engine block load is examined on an in-line four-cylinder naturally aspirated engine in consideration of internal moments of crank train rotating parts. For the analysis are used state-of-the-art methods such as CAD, Finite Elements Method and Multi-body System tools which incorporate flexible bodies, and a computation model of hydrodynamic bearing dynamics.

Tento článek se zabývá studií vlivu velikosti vývažků klikového hřídele na zatížení bloku motoru. Zatížení bloku motoru je významně ovlivněno setrvačnými silami a momenty klikového hřídele zejména ve vyšších otáčkách motoru. Toto zatížení může být významně sníženo vývažky klikového hřídele a jejich vhodným tvarem. Vliv vývažku na vnitřní momenty setrvačných sil rotujících částí, potažmo na zatížení bloku motoru, je zkoumáno u řadového čtyřválcového nepřeplňovaného motoru. Analysa je provedena s použitím nejmodernějších metod CAD, MKP a MBS se zahrnutím pružných těles a výpočtového modelu kluzných ložisek.
