New Approach to Measure Instantaneous Angular Behaviour of a Dual Mass Flywheel 2000-05-0065

The Dual Mass Flywheel (DMF) can be the cause of noises and chock strong enough to be perceived and disturb vehicle occupants. The analysis of this mechanical phenomenon is quite difficult because it requires measurement on a rotating wheel. Real time angular measurement can be performed by using a new system called FURD, developed by CONDIACQ, which requires only two analogue signals coming from inductive sensors mounted on the flywheel and the gearbox. In addition with a crown information picked up from the engine, it is possible to get in real time the absolute angular position of the DMF in the friction curve and so determine more easily the origin of noises and disturbances.
