Abstract
Recently, the eigenvalue analysis and the frequency response analysis using the finite element method (FEM) is commonly used, since the vibration characteristic of the powertrain is an important specification which causes the influence on the booming noise and the durability of each parts. However, the eigenvalue analysis and the frequency response analysis cannot take into account of the dynamic behavior of the cranktrain and thenonlinear characteristics. This paper presents a new approach which considers the dynamic behavior of the crankshaft and thenonlinear oil film characteristics of the main bearings and the engine mounts for accurately predicting the vibration level at the engine mounting points under running conditions. By applying this approach to an in-line four cylinder engine, the predicted vibration level is reasonably comparable with experimental result.
