MODAL SURVEY TESTING AND VIBRATION QUALIFICATION TESTING: THE INTEGRATED APPROACH

摘要

In the process of the structural integrity and launch-environment survivability assessment of satellite structures, dynamic mathematical models are used for load prediction. These analytical models are test-verified by a modal survey test. Once the vibration environment is specified, the satellite equipment is subjected to shaker excitation in order to reproduce this environment. This paper investigates the possibilities to integrate both the modal survey and the vibration qualification test.
