Abstract
Ushbu maqolada tashqi garmonik qo‘zg‘atish (base harmonic excitation) ta’siridagi bir darajali tebranish izolyatsiya tizimida viskoz so‘ndirgichning dinamik javobga ta’siri nazariy va raqamli usullar yordamida tadqiq etilgan. Massa–bahor–so‘ndirgich (SDOF) modeli asos qilib olingan. Tebranish uzatish koeffitsienti (transmissibility), rezonans chastotasi va so‘ndirish darajasi (ζ) orqali tahlil qilingan. Natijalar shuni ko‘rsatdiki, optimal so‘ndirish darajasi (ζ ≈ 0,2–0,25) rezonans hududida tebranish amplitudasini keskin kamaytiradi hamda yuqori chastotali izolyatsiya samaradorligini qoniqarli darajada saqlab qoladi.
