The paper presents new efficient computational and experimental approaches to a powertrain vibration analysis. A complex computational model of a powertrain (a virtual engine) is a powerful tool for the solution of structural, thermal, and fatigue problems. The virtual engine results have to provide answers to different questions, mainly those concerning the area of noise, vibration, and fatigue components. The paper also includes a description of a fast algorithm for hydrodynamic solution of a slide bearing incorporating pin tilting influences. The main contribution is the fact that all models, namely those of the cranktrain, valvetrain, gear timing mechanism and fuel injection pump, are solved simultaneously, using a complex computational model. Synchronous solutions can have a fundamental effect on the results of powertrain dynamics solutions. Additionally, it might help influences between powertrain parts to be understood. The virtual engine is assembled as well as numerically solved as a multi-body system. Virtual engine results are validated by measurements on a diesel in-line six-cylinder engine.
