Abstract
A part evaluation tool is disclosed and which may be used to assess a part-under-test for use in a system. A plurality of natural frequencies for a system operated at a first steady-state operational are identified. A vibrational response of a part-under-test is acquired, and resonance frequencies within this vibrational response are identified. Resonance frequencies of the part-under-test are compared with the identified natural frequencies for purposes of classifying the part as compliant (e.g., suitable for use in the system) or non-compliant (e.g., not suitable for use in the system).
Claims27
A method of evaluating a part, comprising the steps of:
- identifying a plurality of natural frequencies that are generated by operation of a system at a first steady-state operational frequency, wherein said system comprises a first part;
- vibrating a part-under-test by sweeping through a range of frequencies using a first transducer;
- acquiring a first vibrational response to the vibrating of the part-under-test using a second transducer, the same as or different than the first transducer;
- first identifying a plurality of resonance frequencies of said part-under-test from said first vibrational response;
- comparing said plurality of resonance frequencies from said part-under-test with said plurality of natural frequencies from said system;
- and
- classifying said part-under-test based upon said comparing step.
