First Claim
Patent Images
1. A method of evaluating a part, wherein a resonance inspection comprises exciting a part-under-test at a plurality of input frequencies and obtaining a frequency response of a part-under-test at each of said plurality of input frequencies, wherein a surface vibration inspection comprises vibrating a part-under-test and assessing surface vibrations of a part-under test, and wherein said method comprises the steps of:
- conducting a first inspection of a first part-under-test, wherein said first inspection comprises performing said resonance inspection on said first part-under-test;
conducting a second inspection of said first part-under-test, wherein said second inspection comprises performing said surface vibration inspection on said first part-under-test; and
evaluating said first part-under-test based upon each of said first and second inspections, wherein said first part-under-test comprises a plurality of common first structures, wherein said evaluating step further comprises;
identifying an anomaly in results from at least one of said first and second inspections of said first part-under-test; and
conducting a separate said resonance inspection on each first structure of said plurality of common first structures for said first part-under-test, all in response to and after said identifying step, wherein each said resonance inspection of each said first structure from said conducting step of said evaluating step is in addition to the previous-in-time said resonance inspection of said first part-under-test from said conducting a first inspection step.
