摘要

This paper examines the dynamics of a vibro-impact nonlinear energy sink (VI-NES) using a generalized impact map approach. The study incorporates asymmetry and dry friction, reflecting realistic conditions. The proposed method identifies all periodic solutions and determines their stability, and is applicable to various VI-NES configurations, including horizontal and vertical orientations. Numerical results validate prior findings for symmetric frictionless cases and extend them to include frictional and asymmetric dynamics, providing a powerful tool for optimizing the performance of VI-NES in vibration mitigation.
