Ефективність асиметричних односторонніх і симетричних двосторонніх віброударних нелінійних поглиначів енергії тобто віброударних демпферів, для зменшення небажаних коливань основної конструкції є досить високою і подібною для демпферів з різною масою і конструкцією. Однак їхня динамічна поведінка відрізняється. Оптимальна конструкція демпферів з меншою масою має незвичний, «дивний» набір параметрів. Області двостороннього впливу демпфера на обидва бар'єри вузькі і розташовані поблизу резонансної частоти збуджуючої сили.
The efficiency of the asymmetric single-sided and symmetric double-sided vibro-impact nonlinear energy sinks, that is, vibro-impact dampers, for mitigating unwanted vibrations of the main structure are quite high and similar for dampers with different masses and designs. However, its dynamic behavior is different. The optimal design of the dampers with lower mass has unusual, “strange” parameter set. The regions of bilateral damper impacts on the both barriers are narrow and located near the resonant frequency of the exciting force.
