Abstract

The improvement of the prediction power of MBS simulation techniques for valve trains requires in addition to the structural and dynamic properties of the components the consideration of the nonlinear spring and damping characteristics of the hydrodynamic lubrication film in the bearings. The elastohydrodynamic simulation techniques developed at the institute and their connection to commercial MBS programs are described below. The tasks were accomplished within the scope of the FVV projects Dynamische Ventilbelastung and Nockenwellendynamik.
