Influence of stiffness parameters on vibro-impact damper dynamics

The article studies the dynamic behavior of a low-mass vibro-impact damper, considered as device for passive vibration control. Its design scheme corresponds to single-sided nonlinear energy sink (SSVI NES), which is supposed be used effective vibrations attenuation under different transient loads, namely, impulsive, broadband, wind. dynamics and effectiveness strongly depend both on damper own parameters external load parameters. We consider response regimes efficiency two options its optimized periodic loading. influence elasticity characteristics colliding surfaces also analyzed. show that modes with rich complex are implemented in system heavier low stiffness. Despite this, it more effective, especially softer impact.
