Kodi Shock Transmission Unit/Lock-up chipangizo ndi chiyani?
Shock transmission unit(STU), yomwe imadziwikanso kuti Lock-up device(LUD), kwenikweni ndi chipangizo cholumikiza mayunitsi osiyana.Amadziwika ndi mphamvu yake yotumizira mphamvu zowonongeka pakanthawi kochepa pakati pa zomangira zolumikizira pomwe amalola kusuntha kwanthawi yayitali pakati pazigawozo.Ikhoza kugwiritsidwa ntchito kulimbikitsa milatho ndi ma viaducts, makamaka pamene mafupipafupi, liwiro ndi kulemera kwa magalimoto ndi masitima apamtunda awonjezeka kuposa momwe amapangira mapangidwe oyambirira.Itha kugwiritsidwa ntchito poteteza nyumba ku zivomezi ndipo ndiyotsika mtengo pakukonzanso kwa seismic.Akagwiritsidwa ntchito m'mapangidwe atsopano, ndalama zambiri zimatha kutheka pogwiritsa ntchito njira zomangira wamba.
Kodi cholumikizira cha Shock transmission/Lock-up chimagwira ntchito bwanji?
Chida chodzidzimutsa chodzidzimutsa / chipangizo chotseka chimakhala ndi silinda yopangidwa ndi makina opangira ndodo yomwe imalumikizidwa kumapeto kwa kapangidwe kake ndi kumapeto kwina kwa pisitoni mkati mwa silinda.Sing'anga mkati mwa silinda ndi gulu la silikoni lopangidwa mwapadera, lopangidwa ndendende kuti likhale ndi magwiridwe antchito a polojekiti inayake.Zinthu za silicone ndi reverse thixotropic.Pakusuntha kwapang'onopang'ono chifukwa cha kusintha kwa kutentha kwa kapangidwe kake kapena kuchepa komanso kutsika kwa konkriti kwa nthawi yayitali, silikoni imatha kufinya valavu mu pisitoni ndi kusiyana pakati pa pisitoni ndi khoma la silinda.Mwa kukonza chilolezo chomwe mukufuna pakati pa pisitoni ndi khoma la silinda, mawonekedwe osiyanasiyana amatha kupezeka.Kunyamula mwadzidzidzi kumapangitsa kuti ndodo yotumizira ifulumire kudzera pagulu la silikoni mkati mwa silinda.Kuthamanga kumapanga liwiro ndikupangitsa kuti valavu itseke pomwe silikoni silingadutse mwachangu kuzungulira pisitoni.Panthawiyi chipangizocho chimatseka, nthawi zambiri mkati mwa theka la sekondi.
Kodi chipangizo chotumizira zinthu modzidzimutsa/chotseka chimagwira ntchito pati?
1, Cable Stayed Bridge
Milatho ikuluikulu yotalikirana nthawi zambiri imakhala ndi malo osunthika akulu kwambiri chifukwa cha zivomezi.Mapangidwe abwino kwambiri a span amatha kukhala ndi nsanja yolumikizana ndi sitimayo kuti achepetse kusamuka kwakukuluku.Komabe, ngati nsanjayo ikugwirizana ndi sitimayo, mphamvu za kuchepa ndi kukwawa, komanso kutentha kwa kutentha, zimakhudza kwambiri nsanjayo.Ndikosavuta kupanga kulumikiza sitimayo ndi nsanja ndi STU, kupanga kulumikizana kosasunthika mukafuna koma kulola sitimayo kuti iziyenda momasuka panthawi yanthawi zonse.Izi zimachepetsa mtengo wa nsanjayo komabe, chifukwa cha ma LUDs, zimathetsa kusamuka kwakukulu.Posachedwapa, zida zonse zazikulu zokhala ndi nthawi yayitali zikugwiritsa ntchito LUD.
2, Continuous Girder Bridge
The mosalekeza girder mlatho angakhalenso nkhani ngati anayi span mosalekeza girder mlatho.Pali pier imodzi yokha yokhazikika yomwe imayenera kutenga katundu wonse.M'milatho yambiri, chipilala chokhazikika sichingathe kupirira mphamvu zongoyerekeza za chivomezi.Yankho losavuta ndikuwonjezera ma LUD pamabowo okulitsa kuti ma pier onse atatu ndi ma abutments agawane katundu wa seismic.Kuwonjezeredwa kwa LUDs ndikokwera mtengo kwambiri poyerekeza ndi kulimbikitsa pier yokhazikika.
3, Single Span Bridge
Mlatho wosavuta wa span ndi mlatho wabwino pomwe LUD imatha kupanga chilimbikitso pogawana katundu.
4, Anti-seismic retrofit ndi kulimbikitsa milatho
LUD ikhoza kukhala ndi gawo lalikulu pothandizira injiniya pakukweza kapangidwe kake pamtengo wocheperako pakulimbitsa zotsutsana ndi seismic.Kuphatikiza apo, milatho imatha kulimbikitsidwa motsutsana ndi katundu wamphepo, mathamangitsidwe, ndi mphamvu zama braking.
