Exploring the performance of a nonlinear tuned mass damper (2009, methodology): “An alternative design that follows [15] has only the two geometric springs that can be pre-stressed to introduce a linear spring stiffness term.”
Nonlinear Energy Sink for Whole-Spacecraft Vibration Reduction (2017, methodology): “Recently, the NES has been widely applied to engineering practices such as building vibration reduction [50] and aeronautic industries for airfoil aeroelastic instability suppression [51–53].”
Targeted energy transfer with parallel nonlinear energy sinks. Part I: Design theory and numerical results (2011, background): “McFarland et al. [19] and Gourdon et al. [ 20 , 21] experimentally verified theoretical effects of energy pumping with a single NES coupled with single and four dof systems, respectively.”
