Abstract

An experimental approach is described to investigate the vibration characteristics of flexible structures that are susceptible to geometric nonlinearities, such a modern flexible aircraft. The approach enables measurements to be made in the nonlinear regions encountered in-flight, thus exploring the structural nonlinearities, but are performed in such a way that it is easy to compare the experimental predictions with the FE model, thus enabling rapid updating of FE models. The approach is demonstrated upon a number of experimental structures.
