Iyini i-Shock Transmission Unit/Lock-up device?
I-Shock Transmission unit(STU), eyaziwa nangokuthi i-Lock-up device(LUD), iyidivayisi exhumanisa amayunithi esakhiwo ahlukene.Ibonakala ngekhono layo lokudlulisa amandla omthelela wesikhathi esifushane phakathi kwezakhiwo ezixhumayo kuyilapho ivumela umnyakazo wesikhathi eside phakathi kwezakhiwo.Ingase isetshenziselwe ukuqinisa amabhuloho kanye nama-viaducts, ikakhulukazi ezimeni lapho imvamisa, isivinini kanye nezisindo zezimoto nezitimela zikhuphuke ngaphezu kwemibandela yokuklama yasekuqaleni yesakhiwo.Ingase isetshenziselwe ukuvikela izakhiwo ngokumelene nokuzamazama komhlaba futhi ibiza ngempumelelo ekubuyiseleni kabusha kwe-seismic.Uma isetshenziswa emiklamo emisha ukonga okukhulu kungafinyelelwa ngezindlela ezivamile zokwakha.
Isebenza kanjani iyunithi yokudlulisa iShock/Lock-up?
Iyunithi yokudlulisa ukushaqeka/idivayisi yokuvala ihlanganisa isilinda esenziwe ngomshini nenduku yokudlulisela exhunywe ekugcineni kwesinye isakhiwo bese kuthi ngakolunye uhlangothi ixhunywe kwipiston ngaphakathi kwesilinda.Okuphakathi ngaphakathi kwesilinda kuyinhlanganisela ye-silicone eyakhelwe ngokukhethekile, eklanyelwe ngokuqondile izici zokusebenza zephrojekthi ethile.Izinto ze-silicone ziyi-reverse thixotropic.Ngesikhathi sokunyakaza okuhamba kancane okubangelwa ukushintsha kwezinga lokushisa esakhiweni noma ukuncipha kanye nokukhasa kukakhonkolo isikhathi eside, i-silicone iyakwazi ukukhama kuvalvu ku-piston kanye negebe phakathi kwepiston nodonga lwesilinda.Ngokulungisa imvume oyifunayo phakathi kwepiston nodonga lwesilinda, izici ezahlukahlukene zingafinyelelwa.Umthwalo ongazelelwe ubangela ukuthi induku yokudlulisela isheshise ngenhlanganisela ye-silicone ngaphakathi kwesilinda.Ukusheshisa kudala isivinini futhi kwenza ivalvu ivaleke lapho i-silicone ingakwazi ukudlula ngokushesha ngokwanele eduze kwepiston.Kuleli qophelo idivayisi iyakhiya, ngokuvamile phakathi kwesigamu sesekhondi.
Lapho iyunithi yokudlulisa ukushaqeka/idivayisi yokuvala isetshenziswa?
1, I-Cable Stayed Bridge
Amabhuloho amakhulu e-span avamise ukuba nokugudluzwa okukhulu kakhulu ngenxa yokuzamazama komhlaba.Idizayini ekahle ye-span enkulu ingaba nombhoshongo ohlangene nedekhi ukunciphisa lokhu kufuduka okukhulu.Kodwa-ke, lapho umbhoshongo uhlangene nedekhi, amandla okuncipha nokukhasa, kanye nama-gradients ashisayo, athinta kakhulu umbhoshongo.Kuwumklamo olula kakhulu ukuxhuma idekhi nombhoshongo nge-STU, udale uxhumano olungaguquki lapho uthanda kodwa uvumela idekhi ukuthi ihambe ngokukhululeka phakathi nokusebenza okuvamile.Lokhu kunciphisa izindleko zombhoshongo futhi nokho, ngenxa yama-LUD, kuqeda ukufuduka okukhulu.Muva nje, zonke izakhiwo ezinkulu ezinezikhala ezinde zisebenzisa i-LUD.
2, i-Continuous Girder Bridge
Ibhuloho eliqhubekayo lokubhinca lingabhekwa njengebhuloho elinezipanjana ezine eziqhubekayo.Kune-pier eyodwa kuphela engaguquki okufanele ithathe yonke imithwalo.Emabhulohweni amaningi, i-pier engaguquki ayikwazi ukumelana namandla okuzamazama komhlaba.Isixazululo esilula ukungeza ama-LUD ezindaweni zokunweba ukuze zonke izinsika ezintathu zihlanganyele umthwalo wokuzamazama komhlaba.Ukwengezwa kwama-LUD kubiza kakhulu uma kuqhathaniswa nokuqinisa umgodi ongaguquki.
3, Ibhuloho Elilodwa le-Span
Ibhuloho elilula le-span liyibhuloho elikahle lapho i-LUD ingakha ukuqina ngokwabelana komthwalo.
I-4, i-Anti-seismic retrofit kanye nokuqiniswa kwamabhuloho
I-LUD ingadlala indima ebalulekile ekusizeni unjiniyela ekuthuthukiseni isakhiwo ngezindleko ezincane zokuqinisa ukulwa nokuzamazama komhlaba .Ngaphezu kwalokho, amabhuloho angaqiniswa ngokumelene nemithwalo yomoya, ukusheshisa, namandla okubhuleka.
