Pasif kontrol cihazları istenmeyen titreşimlerin azaltılması amacıyla uzun zamandır kullanılmaktadır. Bu cihazlardan en yaygın olarak kullanılanı ise ayarlı kütle sönümleyicilerdir. Bu çalışmada, yer ivmesi etkisindeki sönümlü ana yapılar için üç elemanlı ayarlı kütle sönümleyicilerin optimum parametreleri araştırılmıştır. Geleneksel ayarlı kütle sönümleyicinin aksine, üç elemanlı ayarlanmış kütle sönümleyicide iki rijitlik elemanı bulunur ve bunlardan biri sönüm elemanına seri olarak bağlıdır. Optimum parametreler benzetilmiş tavlama algoritması kullanılarak elde edilmiştir. Sayısal sonuçlar, üç elemanlı ayarlanmış kütle sönümleyici’nin sönümlü ana yapılardaki dinamik titreşimlerin azaltılmasında etkili olduğunu göstermektedir.

Optimum Three-Element Tuned Mass Damper for Damped Main Structures under Ground Acceleration

Öz

Passive control devices have been used for a long time to reduce unwanted vibrations. The most commonly used of these devices are tuned mass dampers. The optimum parameters of the three-element tuned mass damper for damped main structures due to ground acceleration are investigated in this paper. Unlike the traditional tuned mass damper, the three-element tuned mass damper contains two spring elements and one of them is connected in series with the damping element. The optimum parameters are obtained by simulated annealing algorithm. Numerical results show that the three-element tuned mass damper is very effective in reducing dynamic vibrations of the damped structures.
