|Title:||Modal Parameter Identification In The Time Domain From A Random Excitation Force|
|Abstract:||A time domain algorithm for calculating frequencies, damping ratios and modal shape information of a discrete dynamic system is presented. Input and output samples of the system's dynamic excitation and response signals are used to determine the parameters. The algorithm is based on Prony's solution to the complex exponential interpolation of the system's unit impulse response function. The problem of determining resonant frequencies of a steel beam is presented to illustrate a practical application of the algorithm. © 1990.|
