摘要: Abstract This paper investigates the effect of an attached/coupled nonlinear energy sink (NES 1 ) on suppression a cantilever beam under shock excitation. Grounded and ungrounded configurations NES are studied performance is optimized through variation different parameters. The realization vibration control one-way irreversible pumping optimizing system parameters result in acquiring up to 89% dissipation imposed by In addition, bifurcations topological structure normal modes (NNMs 2 both systems order find necessary conditions targeted transfer (TET 3 each configuration. fact, role NNMs identifying dynamics especially continuous for first time.
