Noise and Vibration Reduction - the Cranktrain as a Main Powertrain Module

This paper discusses how the multi-body dynamics approach combined with flexible body effects is being applied to predict the vibrations of crankshaft, bearing loads or cranktrain noise level due to structural flexibility. The oil film effects in the journal bearing are implemented with the use of a finite difference method. An application example of a Diesel inline four-cylinder engine is given in this paper to show this sophisticated simulation model and to predict the dynamic response of the flexible system and loads in the journal bearings.

Keywords: noise, vibration, cranktrain, finite difference method, slide bearing model
