System and method for monitoring component health using resonance

A method of monitoring the health of components of a machine, the method comprising:

• generating acoustic emission (AE) signals that are representative of acoustic emission waves propagating through at least one component of the machine, wherein the at least one component has a damage state and the damage state has a resonance frequency;
• identifying the resonance frequency of the damage state during operation of the machine using received AE signals;
• and
• monitoring the damage state of the at least one component using the received AE signals proximate the resonance frequency of the damage state.

A system for monitoring component health of a machine, comprising:

• an acoustic emission (AE) data receiver for receiving AE signals that are representative of acoustic emission waves propagating through at least one component of the machine, wherein the at least one component has a damage state and the damage state has a resonance frequency;
• a resonance detection system for identifying the resonance frequency of the damage state during operation of the machine using the AE signals;
• and
• a health response system for monitoring the damage state of the at least one component using the AE signals proximate the resonance frequency of the damage state.
