Noise, Vibration & Harshness Development (NVH)

An on-going engineering initiative, AAM’s Noise, Vibration & Harshness (NVH) Development program is delivering significant results by applying state of the art computer analysis techniques and disciplines early in the vehicle development process. AAM’s NVH group uses a sophisticated combination of analytical tools focused on optimizing vehicle systems. The goal: zero perceptible NVH.

The Vehicle & Driveline System Laboratory applies proprietary engineering methodologies for driveline NVH optimization, improving system integration and design robustness, while shortening development cycles. The NVH laboratory is equipped with:

• 4WD Vehicle Chassis Dynamometer (in a semi-anechoic chamber), featuring independent wheel torque control, allowing full-system vehicle analysis.
• All-Wheel-Drive Dynamometer (in a semi-anechoic chamber) featuring the ability to test full all wheel drive systems up to 8000 rpm with ability for induced torgue fluctuation excitation.
• Driveline Dynamometer (in a semi-anechoic chamber).
• Gear Mesh Dynamics Tester.

The lab also includes CAD, CAE and CAT product development tools; an LMS data acquisition system; component and thermal validation.

The result: design and analytical validation of world-class components and systems before the first part is made.
