The recent advances in multiple-input techniques for experimental modal analysis have given the test engineer alternatives for performing aircraft ground vibration tests (GVT). Multiple-input random excitation is one of the methods being used instead of the traditional sine dwell approach. The relative advantages of the random and sine methods are apparent in comparisons made using data from recent aircraft GVT's.
