Summary:

The internal combustion engine, clutch, transmission, propeller shaft, differential, half shafts and driven wheels compose the powerline of a vehicle which, due to several reasons of refinement and weight, offers low noise "counter resistance" to engine irregularity.If the torsional vibration created by the combustion engine is transmitted to the vehicle driveline, it may cause there transmission rattle noise and body boom. The torsional damper integrated into either the clutch disc or the flywheel is applied to provide the driveline with lower torsional vibration optimizing transmission and body noises.In order to achieve torsional damper development time gains, this report presents a collection of elements to analyze the torsional vibrations created by an engine during calibration phase, and preview the vibration response tendency for a specific driveline by computer simulation.It is important to mention that the transmission and body noises cannot be previewed by using this routine, for that vibro-acoustics tools should be applied in association. This proposed method can only indicates a tendency of a powertrain mechanical vibration behavior
