NVH Dynamometers


The Dynamometer provides capability for noise and vibration testing of brake corner and axle fixtures. This machine provides the ability to reproduce a wide range of brake noise issues from moan/groan (low frequency) to squeal (high frequency). The system incorporates state-of-the-art technology for optimal correlation to actual operating conditions.

The brake test cell is separated from the dynamometer drive and support systems to isolate outside noise and vibration sources. The dynamometer enables close correlation with existing certification test protocols including SAE J2521. Additionally, the enclosure is constructed to allow environmental testing using standard environmental conditioning unit. The typical unit provides ranges of -20º C to 40º C and 20 to 90% relative humidity.

The ProLink software package integrates dynamometer operation, digital video, data acquisition, data analysis and reporting.
