Noise, Vibration, Harshness Testing

Noise, Vibration, Harshness (NVH) Testing Systems

As overall vehicle quality continues to improve, driver expectations for a quiet ride have significantly increased the number of warranty returns associated with noise and vibration from powertrain components. NVH test equipment ensures a sellable product, free of gear mesh inaccuracies that may result in premature wear, vibration, axle whine, knicks-clicks or harsh noises that may disturb the occupants of the cab.

Main NVH Testing Systems

BPG NVH testing machines can be used to test axles, power take-off units (PTUs), manual transmissions, and transfer cases. We can also test both light and vehicles for NVH ratio verification, speed sweeps, torque sweeps, and drag functionality. The NVH software package provides a real-time, visual display that allows the operator to immediately access the sound profile of the test part. Data can also be stored for review at a later date.

Our NVH testing equipment can also be integrated into any automated production line to provide a complete, turnkey system including electrical, pneumatic, and hydraulic controls hardware design, PC, PLC, robotics, and instrumentation software programming and setup. The BPG full spectrum of services include design and engineering, manufacturing and assembly, installation, service, and support.
