Iyini i-mass damper eshuniwe?
I-tuned mass damper(TMD), eyaziwa nangokuthi i-harmonic absorber, iyithuluzi elifakwe ezakhiweni ukuze kuncishiswe i-amplitude yokudlidliza kwemishini.Ukusetshenziswa kwabo kungavimbela ukungakhululeki, ukulimala, noma ukwehluleka ngokuphelele kwesakhiwo.Asetshenziswa kaningi ekudluliselweni kwamandla, ezimotweni nasezakhiwo.I-damper mass eshuniwe isebenza kahle kakhulu lapho ukunyakaza kwesakhiwo kubangwa imodi eyodwa noma ngaphezulu ezwakalayo yesakhiwo sokuqala.Empeleni, i-TMD ikhipha amandla okudlidliza (okungukuthi, yengeza ukudambisa) kumodi yesakhiwo "eshuniwe" kuyo.Umphumela: isakhiwo sizizwa siqinile kakhulu kunalokho esiyikho ngempela.

Isebenza kanjani i-mass damper eshuniwe?
I-TMD iyinhlanganisela yezinhlelo ezintathu ezibalulekile: isistimu enkulu, isistimu yokuqina, kanye nesistimu yokuchithwa kwamandla (i-damping), ngakho-ke kunezinhlobo ezintathu zokushuna ezidingekayo ekwakhiweni kwe-TMD.Ukuqina nesisindo se-TMD kukhethwa ukuze kunikeze imvamisa yokuzwakala kwe-TMD eseduze kakhulu nefrikhwensi ye-resonance yesakhiwo.Izinga lokudambisa i-TMD likhethiwe ukuze kuthuthukiswe ukuchithwa kwamandla ngaphezu komkhawulokudonsa osebenzayo we-TMD.Isisindo se-TMD sikhethwa ukunikeza izinga elifiswayo lokunciphisa ukudlidliza.Futhi lapho ukudlidliza kufika esakhiweni, i-TMD izodala amandla ahlukile anemvamisa efanayo yokudlidliza.Lokho kuzosiza ukwehlisa nokulawula ukudlidliza ngempumelelo.
Lapho i-mass damper eshuniwe isebenza khona?
I-damper enkulu eshuniwe ifanele ubude nobude bezakhiwo nezakhiwo okulula ukushukunyiswa isici sangaphandle(njengomoya, ukuhamba kwabantu).Kunganciphisa ngempumelelo ukudlidliza okugqugquzelwa izici zangaphandle.Ama-TMD asetshenziswa kabanzi ezindaweni ezilandelwayo zohlelo lokusebenza.
1, Amabhuloho, uhlaka lwamabhuloho, ushimula, umbhoshongo we-tv nezinye izakhiwo ezinde nezicwebezelayo ezizoshukunyiswa umoya kalula.
2, Iladi, ihholo, ibhuloho lezinyawo zabagibeli nezinye izinto ezizokhuthazwa ukuhamba kwabantu nokugxuma.
3, Imboni yemboni kanye nezinye izakhiwo zensimbi nezinsiza okulula ukukhuthazwa imvamisa yemvelo yemishini.
I-TMD ingaphansi kokuhlolwa kokuhamba nokugxuma esikhumulweni sezindiza
