Umgangatho ophezulu we-Mass Damper oLungelweyo

Umgangatho oPhezulu we-Mass Damper oFakelweyo Umfanekiso

Inkcazelo emfutshane:

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.

Yintoni isidambisi-manzi esilungisiweyo?

Sisebenza njani isidambisi-manzi esilungisiweyo?

I-TMD yindibaniselwano yeenkqubo ezintathu ezibalulekileyo: inkqubo yobunzima, inkqubo yokuqina, kunye nenkqubo yokutshatyalaliswa kwamandla (i-damping), ngoko ke kukho iindlela ezintathu zokulungisa ezifunekayo ekuyilweni kwe-TMD.Ukuqina kunye nobunzima be-TMD bakhethwa ukunika i-TMD resonance frequency kufutshane kakhulu kwi-resonance frequency yesakhiwo.Inqanaba lokuthomalalisa i-TMD likhethiwe ukuze kuphuculwe ukuchithwa kwamandla ngaphezu kwe-bandwidth esebenzayo ye-TMD.Ubunzima be-TMD bukhethwa ukunika inqanaba elifunekayo lokunciphisa ukungcangcazela.Kwaye xa i-vibration ifika kwisakhiwo, i-TMD iya kudala amandla achaseneyo kunye nokuphindaphinda okufanayo kwe-vibration.Oko kuya kunceda ukunciphisa nokulawula ukungcangcazela ngokufanelekileyo.

Apho isixhobo sokudambisa ubunzima esilungisiweyo sisebenza kuso?

Isidambisi manzi esilungisiweyo sifanelekile kubude obude kunye nezakhiwo ezinamandla kunye nezakhiwo ezilula ukuvuselela izinto zangaphandle (ezifana nomoya, ukuhamba kwabantu).Inokunciphisa ngempumelelo i-vibration ekhuthazwa yimiba yangaphandle.Ii-TMD zisetyenziswa ngokubanzi kwiinkalo zesicelo ezilandelwayo.

I-1, iibhulorho, i-pyller yeebhulorho, itshimini, i-tv tower kunye nezinye izakhiwo ezide nezinevimineous eziya kuba lula ukukhuthazwa ngumoya.

2, Ileli, iholo, ibhulorho yeenyawo zomkhweli kunye nezinye izixhobo eziya kukhuthazwa kukuhamba nokutsiba kwabantu.

I-3, iplanti yeshishini kunye nezinye izakhiwo zentsimbi kunye nezixhobo ekulula ukuba zivuselelwe ngokuphindaphindiweyo komatshini.
