Facility 403:  Modal Test Facility

 

The Modal Test Facility at Goddard Space Flight Center (GSFC) is used to measure dynamic response characteristics of aerospace structures. Test items are mounted to the facility seismic block via a T-Slot table to simulate a fixed boundary condition. The facility is serviced by three bridge cranes that provide a convenient method of supporting up to four electro-dynamic shakers. The facility is supported by a digital data acquisition system that has the capability to simultaneously record raw data time signals while processing the data into spectrums, FRF’s, and coherence functions in real time. Post-test curve fitting algorithms within the modal software extract the estimated modal parameters from the test data.
