The Resonant Acoustic Method is a form of Resonant Inspection (RI).

NDT can detect imperfections such as variances in overall shape, weight, cracks, and density of parts. It can also detect if any process has as been missed, such as a machine or heat treating process.

Resonant Nondestructive Testing

Page 4: RAM-NDT Resonant Acoustic Nondestructive Testing Application

Every part has its unique vibration signature (its resonant frequency). This resonance will be almost exactly the same from good part to part. However it will change when there is an internal or external change or imperfection.

Pipe organs, bells, carillons and xylophones are examples of how controlled incremental changes in a part create incremental changes in “resonance” or tone.

When a bell cracks however, it doesn’t have a clear ring, it is flat or dull sounding. It looses the ability tohold it’s tone.

The same is true of a part that has a flaw.

Resonant Acoustic Method

IMPACT

Part is excited by applying a known and repeatable force. This is accomplished by either an electric or manual hammer.

MEASUREMENT

The acoustic response is measured by the microphone and digitized by the Smart Digital Controller

PERFORM FFTThe Smart Digital Controllerperforms an FFT on the data,taking it from the time domainto the frequency domain

ANALYZE

NDT-RAM compares the results with the acceptable criteria limits to determine if the part is accepted or rejected

ANALYZING

Resonant Signature

Resonant Signature

X Axis is from 0 - 40,000 Hz

The result is a response frequency spectrum that is unique to your part. Using this spectrum, we can look for significant structural changes in your parts.

The principal properties of an object are

• Mass

• Stiffness

• Damping

With the NDT-RAM system, you can be online in one day.

After an acceptable range of resonant signatures from a set of good parts is established, each new part is tested by comparing its signature to the acceptable ranges and limits.
