The system is conceived for vibration measurement in completed vehicles during the EOL tests in the rolling test bed. The aim is to identify vibrations that ate caused through unbalances and errors in assembly. Integration into the rolling test bed is typically done in the area between the rollers for either the front or the rear axel. This allows you to achieve measurement points on the drive train in the are of the rear axel or the gearbox. Both a complete frequency analysis of the vibration signal and the unbalance of the drive train for example, can be determined through the speed-related measurement data recording and evaluation, which is usually done using the speed of a drive shaft. The system determines the required compensation for the unbalance, which can be achieved using a wide range of methods, e.g. the application of weights to the flange between the cardan shaft and the differential.
Vibration measurement at the vehicle
