Experimental verification of TET will be carried out in this chapter. Some preliminary experimental results concerning TET from a two-DOF linear primary system to an attached ungrounded SDOF NES (of Configuration II — see Section 3.1) were already presented in Section 3.5.1.3, where experimental verification of resonance capture cascades (RCCs) was also performed. In this chapter we focus on some basic experimental tests that confirm in a systematic way certain of the previous theoretical predictions related to TET from linear primary systems to grounded or ungrounded NESs (i.e., NES Configurations I and II — see Sections 2.6 and 3.1). All experimental results were carried out in the Linear and Nonlinear Dynamics and Vibrations Laboratory of the University of Illinois, Urbana—Champaign. Further experimental studies of TET will be presented in Chapter 9, in our study of aeroelastic instability suppression of in-flow wings through the use of SDOF NESs with essential cubic nonlinearities; and in Chapter 10, in our study of TET-based passive seismic mitigation designs for seismically forced structures with essentially nonlinear and/or vibro-impact NESs.
