INVESTIGATIONS ON THE CLUTCH, CRANKSHAFT, DUAL MASS FLYWHEEL AND DAMPER
The two-channel speed measurement is used to determine torsion angles between the primary and secondary sides of the clutch. Among other things, crankshaft torsion, clutch slip and damper behavior can be measured and evaluated. An engine run-up and subsequent order analysis is used to identify the critical operating conditions and helps with the optimum design of the components. In the clutch measurement shown as an example, speed measurement takes place by means of a magnetic sensor on the starter ring gear and on the transmission input shaft. Main analyses are the torsional angle between engine (input) and gearbox side; slip; order analysis; especially angular acceleration in the gearbox (gearbox rattling).
In the ROTEC product portfolio, you will find a variety of different speed sensors (laser and magnetoresistive) to suit the installation situation, the ambient conditions and the optimum signal resolution. In order to be able to measure the torsion angle between two speed signals with high resolution, ROTEC offers speed measurement boards with 12,3 GHz. At the same time, further analog signals with (max. 24 bit and 3,2 MHz) can be recorded and thus a correlation between torsional vibrations e.g. noises can be analyzed.
Furthermore ROTEC ENGINEERING provides you with support and technical engineering know-how for problems related to vibration analysis of engines, transmissions and drive trains. With our know-how, we make a valuable contribution to your product in the areas of timing gear validation, valve train optimization, clutch design, transmission errors (TE), transmission optimization, oil supply optimization, powertrain measurement and optimization, measurement technology application.
