Automated Resonant Inspection to Validate Resonant Frequency Characteristics within Brake Components for Improved NVH Performance 2010-01-1699
Resonant Inspection is a non-destructive test technique that measures the structural dynamic signature of an article. By comparing the resulting footprint to expected signatures, anomalous outliers are sorted due to some inherent structural defect, improving quality and consistency of manufactured components. Brake components, such as rotors and drums, are designed with specific structural dynamic properties for desired NVH qualities. Resonant Inspection via the Resonant Acoustic Method (RAM-NDT) provides a proven economical technique with the capacity for accurate, reliable and high-throughput 100% online inspection.
