Original abstract

The paper presents computational and experimental approaches to a powertrain vibration analysis. A complex computational model of a powertrain – a virtual engine is a powerful tool for a solution of structural, thermal and fatigue problems. The virtual engine results should answer different questions, mainly those concerning the area of noise, vibrations and component fatigues. The paper also includes a description of fast algorithm for a hydrodynamic solution of a slide bearing incorporating pin tilting influences. The main contribution is the fact that all models, that is those of a cranktrain, a valvetrain, a gear timing mechanism and a fuel injection pump are solved simultaneously, using a complex computational model. Synchronous solutions can have a fundamental effect on results of powertrain dynamics solutions. Additionally, it might help to understand influences among powertrain parts. The virtual engine is assembled as well as numerically solved in Multi Body System. Virtual engine results are validated by measurements on Diesel in-line six-cylinder engine.
