Brake NVH Dynamometer with Environmental Control
Standards Compliant Testing
SAE J2521 – Brake Noise Test Method (AK Master) | SAE J2598 – Brake Creep Groan Test Method | ISO 26867 – Brake NVH dynamometer testing
Why Environmental Control Is Critical for Brake NVH Testing
Brake Noise, Vibration and Controlled Environmental Testing for Brake Noise, Vibration and Harshness Validation – Harshness (NVH) phenomena are highly sensitive to ambient temperature, humidity, airflow, and thermal history
Innovation Rooted in Engineering Depth
Testing brake systems without controlled environmental conditions often leads to inconsistent results that do not correlate with real-world vehicle behavior.
CME Brake NVH Dynamometer Environmental Chambers enable precise control of temperature, humidity, and airflow around brake dyno systems—delivering repeatable, standards-compliant NVH validation.
Purpose-Built Environmental Chambers for Brake NVH Dynos
CME designs environmental chambers specifically engineered to integrate with brake NVH dynamometers.
These chambers control the surrounding test environment while allowing accurate mechanical operation, instrumentation access, and acoustic measurement.
Controlled Temperature, Humidity and Airflow
CME chambers provide stable control of ambient temperature and humidity to evaluate brake noise behavior across different climatic conditions.
Conditioned airflow systems simulate vehicle cooling air and ensure repeatable thermal and acoustic conditions during test cycles.
