Modally Tuned ICP® Impact Hammers
| Resonance testing and modal analysis are excellent root-cause failure analysis techniques. Impacting a structure excites it with a broadband force. This excitation causes the structure or machine to vibrate at its natural or resonant frequencies. Through the use of a two-channel data collector that measures the ratio of the vibratory response (typically measured with an accelerometer) to the input force (generated and measured with an impact hammer), a frequency response function (FRF) results, which identifies problem resonances. IMI's Modally Tuned® ICP® Impact Hammers, ideally suited for this type of testing, are equipped with a series of removable tips for modifying the amplitude of the applied force and the frequency range of excitation. |
