27. A method of determining the vibrational response of a structural element, comprising the steps of:
-
sensing an output of the structural element in response to a force input imparted to the structural element;
calculating frequency response data for the structural element from the sensed output of the structural element;
determining a single amplitude value from the frequency response data;
determining a peak frequency from the frequency response data;
associating the single amplitude value with the peak frequency;
providing at least one predetermined vibration criterion, the or each criterion comprising a plurality of amplitude values, each amplitude value having an associated frequency value; and
comparing the single amplitude value with the amplitude value of the or each criterion associated with the peak frequency. - View Dependent Claims (28, 29, 30, 31, 32, 33)
