Implementation of Ground Vibration Test (GVT) on Large Aircrafts

Ground vibration test (GVT) is one of the standard structural tests required for designed passenger aircrafts. This test is performed to derive the experimental dynamical model of aircraft structure. The process of executing this test involves test planning, structural preparation, data gathering, and extraction of dynamic parameters from the test data. In the present study, the practical implementation process of each step is described. Given the size and complexity of this test, certain techniques, hardware, and software are to be investigated. The global experience of performing this test is briefly discussed. Finally, a typical setup for a ground vibration test of a large aircraft is introduced and described.
