Chii chinonzi Shock Transmission Unit/Lock-up mudziyo?
Shock transmission unit(STU), inozivikanwawo seLock-up device(LUD), chiri chigadziriso chinobatanidza zvikamu zvakasiyana zvezvimiro.Iyo inoratidzirwa nekugona kwayo kuendesa mauto enguva pfupi-pfupi pakati pekubatanidza zvimiro uku ichibvumira kufamba kwenguva refu pakati pezvivakwa.Inogona kushandiswa kusimbisa mabhiriji uye viaducts, kunyanya mumamiriro ezvinhu apo kuwanda, kumhanya uye huremu hwemotokari uye zvitima zvakawedzera kudarika maitiro ekutanga ekugadzirwa kwechimiro.Inogona kushandiswa kudzivirira zvivakwa kubva pakudengenyeka kwenyika uye inodhura inoshanda seismic retrofitting.Kana yakashandiswa mumagadzirirwo matsva mari yakawanda inogona kuwanikwa pamusoro pemaitiro ekuvaka akajairika.
Iyo Shock transmission unit / Lock-up mudziyo unoshanda sei?
Iyo yekuvhundutsa yekufambisa unit / yekuvhara-up mudziyo unosanganisira cylinder yemuchina ine tsvimbo yekufambisa iyo yakabatana kune imwe mugumo kune chimiro uye kune imwe mugumo kune piston mukati mehumburumbira.Iyo yepakati mukati me cylinder ndeye yakanyatso kuumbwa silicone komisheni, yakanyatso kugadzirirwa maitiro ekuita kwechimwe chirongwa.Iyo silicone zvinhu ndeye reverse thixotropic.Munguva yekufamba zvishoma nezvishoma kunokonzerwa nekushanduka kwekushisa muchimiro kana shrinkage uye kwenguva refu inokambaira yekongiri, iyo silicone inokwanisa kudzvanya nepakati pevharuvhu mupiston uye gaka pakati pepiston uye cylinder madziro.Nekugadzirisa iyo inodiwa clearance pakati pepiston uye cylinder madziro, akasiyana maitiro anogona kuwanikwa.Kamwe kamwe mutoro unokonzera kuti tsvimbo yekufambisa iwedzere kuburikidza nesilicone compound mukati mehumburumbira.Iko kukwirisa kunokurumidza kugadzira velocity uye kuita kuti vharafu ivharwe uko iyo silicone isingakwanise kupfuura nekukasira kutenderedza piston.Panguva ino mudziyo unovhara, kazhinji mukati mehafu yechipiri.
Ndekupi kuvhunduka kwekutapurirana unit/lock-up mudziyo unoshanda?
1, Cable Yakagara Bridge
Mabhiriji mahombe epamhepo anowanzo kuve nekusarudzika kwakakura zvakanyanya nekuda kwekuita seismic.Iyo yakanakira yakakura span dhizaini yaizove neshongwe yakabatana nedhizaini yekudzikisa uku kusimuka kukuru.Nekudaro, kana iyo shongwe yakabatana nedhishi, masimba ekuderera uye zvinokambaira, pamwe nekupisa kwemafuta, zvinokanganisa zvakanyanya shongwe.Iyo iri nyore dhizaini yekubatanidza dhizaini neshongwe neSTU, ichigadzira iyo yakagadziriswa yekubatanidza kana ichidikanwa asi ichibvumira dhizaini kufamba zvakasununguka panguva yenguva dzose mashandiro.Izvi zvinoderedza mutengo weshongwe uye zvakadaro, nekuda kweLUDs, inobvisa iyo yakakura kutamiswa.Munguva pfupi yapfuura, ese makuru zvimiro ane marefu marefu ari kushandisa iyo LUD.
2, Inoenderera Girder Bridge
Rinoenderera mberi girder zambuko rinogona zvakare kutariswa sechina-span inoenderera girder zambuko.Pane imwe chete yakagadziriswa pier iyo inofanirwa kutora mitoro yese.Mune mabhiriji akawanda, iyo yakagadziriswa pier haikwanisi kumira ne theoretical masimba ekudengenyeka kwenyika.Mhinduro yakapusa ndeyekuwedzera maLUDs pamapier ekuwedzera kuitira kuti ese matatu piers uye abutments agovane seismic mutoro.Kuwedzerwa kweLUDs kune mutengo unoshanda kana uchienzaniswa nekusimbisa yakagadziriswa pier.
3, Single Span Bridge
Iyo yakapfava span bhiriji ibhiriji rakanakira uko iyo LUD inogona kugadzira kusimba kuburikidza nekugovana kwemutoro.
4, Anti-seismic retrofit uye kusimbiswa kwemabhiriji
Iyo LUD inogona kuita basa rakakura mukubatsira mainjiniya mukusimudzira chimiro pamutengo wakaderera wekusimbisa-seismic.Pamusoro pezvo, mabhiriji anogona kusimbiswa kurwisa mitoro yemhepo, kukurumidza, uye mabhureki masimba.
