Acoustics and Vibrations

Noise problem by continuous speed

Due to increasing vehicle comfort demands as well as increasing noise and vibration behaviour requirements the research of acoustic and vibration characteristics has become more and more important. With regard to these aspects, GIF is able to offer the following methods:

Vehicle analysis

Evaluation of vehicle components effect on the in-vehicle noise behaviour of the complete vehicle.

NVH-Powertrain Test Benches

Vibration optimisation of the total powertrain system.

ATE Test Benches

(Anechoic Test Chamber for Transmissions with Engine Torque Pulsation Simulation)

Acoustic semi free field measuring in an acoustic chamber to examine transmission rattling and gear whine.

Sound Intensity

Independent sound source location and measuring.

Torsional Vibration Damping

Development and functional analysis of torsional vibration dampers of the vehicle powertrain
