Impulse excitation technology offers a modern solution

摘要

Impulse excitation technology (IET) is based on the analysis of the vibration of a specimen after it was 'impulse excited' (gently tapped). The resonance frequencies of impulse excitation technology are characteristic for the test object, as they are related to its stiffness, mass, and geometry The relationship between resonant frequency and the elastic properties has probably been known since man started selecting better materials for his percussion instruments, This knowledge has been inverted much later, using the resonant frequency to determine the elastic properties of materials.
