000004789 520__ $$2eng$$aAs part of a study of energy pumping in nonlinear multi-degree-of-freedom systems, a 2-DOF test rig comprising a linear, SDOF primary system weakly coupled to a nonlinear energy sink (NES) has been built to operate on an existing bench-top air track. The static and dynamic behavior of the various components and of the system as a whole has been measured to facilitate comparison of experimental and simulated responses. Several of the subsystems are linear and have been characterized by conventional modal analysis, for example by hammer tests, but the proper functioning of the NES depends upon the generation of an essentially nonlinear restoring force; the design and calibration of the cubic-hardening nonlinear spring used for this purpose are discussed in detail. This paper presents the nominal and measured values of all the system parameters.
