The NVH test rig measures noises, vibrations and harshness (NVH = Noise Vibration Harshness). Drive shafts generate forces that simulate the load conditions in the car as they would occur on the road.
•Axial excitation by means of hydraulics
•Force measurement with Piezo force sensors
•Axial force measurement with Piezo force sensors
•Torque applied to the specimen
•Shaft rotation
•Articulation of fixed joint and plunge joint
•Axial displacement of plunge joint
•High-frequency axial excitation of the specimen with a hydraulic shaker
