ABSTRACT:
A method for temperature compensation of resonant frequency measurements of parts uses Temperature Functions which are mathematical relationships between measured resonant frequencies and temperature. The Temperature Function is used to adjust frequencies measured at any temperature to a resonant frequency at a pre-determined reference temperature. The temperature of a surrogate part or specimen can be measured to eliminate the need to touch a part being tested where the surrogate part has essentially the same dimensions and material properties and is positioned and mounted such that its temperature is essentially the same as the part being tested. The temperature function may be in the form of
