STUDY OF NON-LINEAR STRUCTURE USING AN ELECTRONIC SLAVE HAMMER

Special electrical and mechanical devices are used to obtain an electronic many-head slave hammer which can produce successive force impulses with adjustable delays. We show how to use this hammer to decompose the structure response into components of various orders. The scientific framework is the Volterra series. Evaluation of impulse responses of different orders is presented as well as corresponding transfer functions. Eigenvalues of various orders are then evaluated and interpreted.
