TORSIONAL VIBRATION ANALYSIS FOR HEAVY-DUTY VEHICLES

Previous
Next

The increasing demands placed on heavy-duty commercial vehicle engines in terms of efficiency, emissions, friction, performance and acoustics call for continuous improvement and optimization of the powertrain. This requires, among other things, reliable vibration measurements and analyses of the individual components of the belt or chain drive, the valve train and the transmission. With our measurement system, we guarantee precise, reliable and fast analysis results for  ex. slip analysis, stress balancing and resonance and stress analysis.

TIMING AND AUXILIARY DRIVE

The optimization of timing and auxiliary drives  requires reliable vibration measurements and analyses of the individual components of the belt or chain drive. With our measuring system, we guarantee precise, reliable and fast analysis results of slip analysis, tension tuning as well as resonance and stress analysis.

VEHICLE TRANSMISSION

In the development of heavy-duty engines, noise reduction in the transmission is an important development goal. Rattle and rattling noises occur predominantly in synchronized vehicle transmissions under torsional vibrations or when excited by gear teeth. We provide you with a powerful, high-resolution measuring system and engineering know-how with which you can check transmission units for noise and perform vibration analyses.

VALVE TRAIN

Valve train systems control charge changes and are therefore a key factor in achieving emission and consumption targets. The components of the valve train system are exposed to high loads due to mechanical forces and temperatures. To avoid this, you must measure them precisely and adjust them optimally. We provide you with market-leading measurement technology for this purpose. Important analysis includes stroke, speed and acceleration, opening and closing behavior as well as resonance and stress analysis.

COUPLING, TORSIONAL DAMPER AND DUAL MASS FLYWHEEL

For the design, tuning and optimization of clutches, torsion dampers and dual mass flywheels in heavy-duty trucks you can use the mobile, compact ROTEC systems on the test bench and in driving tests. 

NOISE, VIBRATION, HARSHNESS

Self-excited friction oscillations, which cause body to airborne noise, lead to undesired driving noises. We offer you reliable investigations of noise, vibration and harshness with suitable measurement technology and expert knowledge.

This requires reliable vibration measurements and analyses of the individual components of the belt or chain drive. With our measuring system, we guarantee precise, reliable and fast analysis results of slip analysis, tension tuning as well as resonance and stress analysis.
