I-tuned mass damper (TMD), eyaziwa ngokuba yi-harmonic absorber, sisixhobo esifakwe kwizakhiwo zokunciphisa i-amplitude ye-vibrations mechanical.Ukusetyenziswa kwabo kunokuthintela ukungahambi kakuhle, umonakalo, okanye ukungaphumeleli okucacileyo kwesakhiwo.Zihlala zisetyenziselwa ukuhanjiswa kwamandla, iimoto, kunye nezakhiwo.Isidambisi sobunzima esilungisiweyo sisebenza kakhulu apho intshukumo yolwakhiwo ibangelwa yimowudi enye okanye ezingaphezulu zeresonant yesakhiwo sokuqala.Ngokwenene, i-TMD ikhupha amandla okungcangcazela (okt, yongeza ukudambisa) kwimowudi yesakhiwo "ilungiswe" kuyo.Isiphumo sokugqibela: isakhiwo siziva siqinile ngakumbi kunokuba sinjalo.
