ABSTRACT:
A computer-implemented apparatus and method for operating vibrational testing equipment which conducts vibrational testing upon automobile components. Raw engine acceleration data is gathered from a running car so that a sine on random calculation may be performed upon that data. The sine on random calculation uses peak hold envelope data and sin tone data as determined from the acceleration data. Thereupon, an iterative equalization technique operates upon the peak hold envelope data and sine tone data to generate a vibrational testing specification. The vibrational testing specification defines how the vibrational testing equipment should operate by specifying such parameters as the gain, the sweep duration, and the time to run the vibrational test in order to achieve a particular reliability and confidence level.
