Targeted energy transfer in a vibro-impact cubic NES: Description of regimes and optimal design

In this study, we address the response regimes of a novel Nonlinear Energy Sink (NES) that couples both cubic and impact nonlinearities. non-smooth condition, conventional multiple scales method is considered with condition. By identifying occurrence collision, asymptotic analysis equivalent NES model Vibro-Impact (VI) can illustrate fixed point Cubic (VIC) NES. Three types VIC are described as function clearance length. The role length on provided, offering solid criteria for optimal design. Combined simulation results, our experimental observations prove restraint effect robustness Strongly Modulated Response (SMR).
