Time Domain Analysis of Base-driven Transient Tests.

Füllekrug, U. (1993) Time Domain Analysis of Base-driven Transient Tests. Modal Analysis: The International Journal of Analytical and Experimental Modal Analysis, v 8 n 3 Jul 1993, No. 3, pp. 205-218.

Since future qualification concepts for spacecraft tend to integrate base-driven transient tests, a modal identification of the transient structural vibrations could reveal important dynamic characteristics. In this paper the theoretical basis of a time domain identification method is outlined, fundamental equations are summarized, and the first application on a base-driven transient test is described. A structural model of a satellite mounted onto a multi-axis vibration simulator was excited in the low frequency range by a uniaxial transient base point acceleration signal. Time histories of base point accelerations and structural responses were postprocessed and analyzed by the identification algorithm. Results for modal parameters are compared with those of a frequency domain modal analysis.
