Original Abstract

This article presents computational approaches for verification of conceptual study of low-friction-losses cranktrain 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.
