Abstract

It is well known that powertrain vibration characteristics are a critical factor influencing booming and other cabin noises. As vibration at the engine mounting points is one of the most influential of all the vibrations a precise analytical method for the prediction of vibration at the engine mounting points under running conditions was developed. This method uses simulation models that take into consideration the nonlinear characteristics of both main bearing’s oil film and the engine mounts. This makes it possible to predict the vibration level at engine mounting points while preserving a practical level of accuracy. Application of this design method during the initial stages of basic powerplant structural investigations for powertrain design will enable the efficient evaluation of powertrain vibration characteristics.
