W niniejszym artykule zbadano efektywność tłumienia drgań i wstrząsów przez tłumiki semiaktywne, opisane modelami histerezowymi typu Bouc-Wena i Spencera. Zastosowano dwa algorytmy typu on-off sterowania parametrami tłumika. Rezultaty obliczeń porównano z odpowiednimi wynikami otrzymanymi dla układów pasywnych. Wykazano pewne różnice jakościowe w zachowaniu się obu modeli w zakresie niższych częstości.

The paper has investigated the efficiency of vibration and shock damping through semiactive absorbers described by the Bouc-Wen and the Spencer models. Two algorithms of on-off control type were applied to change the values of dissipative parameters. The results of calculations were compared with suitable results obtained for passive systems. Some qualitative differences of dynamical behaviour of the Bouc-Wen and the Spencer models were shown in the lower frequency range.
