Kupanga Mizere Yoteteza Maso ndi Mafupa a Nanoscale: Kuchotsa Luso Lodabwitsa la Maziko a Granite

Kuchepa Kwachilengedwe kwa Mapangidwe a Crystalline Network

Ngakhale kuti zipangizo zachitsulo zili ndi ntchito yabwino yopangira makina, zikakumana ndi zovuta zovuta, liwiro lochepa la mafunde awo amkati nthawi zambiri silikhala lokwanira, zomwe zimapangitsa kuti zikhale ndi michira yozungulira. Mosiyana ndi zimenezi, miyala yakuda yopangidwa mwachilengedwe imasonyeza luso losiyana kwambiri.

Mwachitsanzo, pogwiritsa ntchito granite wakuda wapamwamba kwambiri wosankhidwa ndi ZHHIMG Group (ZHHIMG®), kagwiridwe kake ka mphamvu kakuphwanya malire apamwamba a miyala yachikhalidwe (kufika pafupifupi $3100\,\text{kg/m}^3$). Matrix a kristalo wokhuthala kwambiri wa mchere uwu umapanga munda wachilengedwe wotaya mphamvu pamlingo wa microscopic. Pamene mafunde akunja okhala ndi mafunde amphamvu kapena otsika amayesa kulowa pansi, malire a tirigu ofalikira kwambiri ndi malo olumikizirana a mchere ambiri amachita ngati ma miniature dampers ambiri, zomwe zimasintha mphamvu ya kinetic kukhala kutentha pang'ono ndikuichotsa. Kuchepetsa kwamkati kwapadera kumeneku kumathandiza maziko a granite kukhala ndi "buleki yadzidzidzi" nthawi yomweyo chisokonezo chikachitika, kuletsa kukula kwa nanoscale.

Khodi ya Jiyometri Yotsutsana ndi Nthawi ndi Kuyenda kwa Kutentha

Kukana kugwedezeka kwamphamvu ndi gawo loyamba lokha lotsimikizira kukhazikika kwa njira yowunikira, ndipo kukhazikika kwa nthawi yayitali kwa kapangidwe kake ndi mayeso ena ovuta. "Kugwedezeka" kulikonse kapena kutulutsidwa kwa kupsinjika kumawononga coaxiality ya njira yowunikira yokonzedwa bwino.

Granite yapamwamba kwambiri yatulutsa mphamvu zokwanira mkati mwa nthawi yonse ya kusintha kwake kwa geological. Makhalidwe ake a mankhwala ndi okhazikika kwambiri; alibe dzimbiri, sagonjetsedwa ndi asidi-alkali, ndipo ali ndi coefficient yochepa kwambiri ya kutentha. Kuti ayambe bwino jini iyi, kupanga kwamakono kolondola kwambiri kumakwaniritsa zosintha zapamwamba kudzera mu pulogalamu ndi zida ziwiri zotsekedwa. Mwachitsanzo, kuyika maziko a granite akuluakulu kwambiri m'malo ochitira masewera olimbitsa thupi otentha nthawi zonse, chinyezi nthawi zonse, komanso opanda fumbi omwe amamangidwa ndi kutsanulira konkire wolimba kwambiri komanso wozunguliridwa ndi ngalande zotsutsana ndi kugwedezeka, komanso kugwirizana ndi opukusira a CNC okwera mtengo komanso akatswiri akale omwe ali ndi zaka zoposa makumi atatu zokumana nazo pamanja pomaliza nanoscale. Njirayi - kuphatikiza "zinthu zapamwamba kwambiri + kukonza kwanzeru kwa digito + kumaliza nanoscale" - kumawonetsetsa kuti mazikowo akhoza kukhalabe ndi datum yangwiro ya geometric pambuyo pa zaka zambiri za ntchito yayikulu komanso yosinthasintha yachilengedwe.                               

Mapeto Akuthupi a Kuteteza Njira Zowala

Mu ntchito ya uinjiniya wa kuwala, maziko abwino kwambiri a granite bench akhala akuposa tanthauzo lachikhalidwe la "bearing flat plate." Amameza phokoso lovuta la kugwedezeka kuchokera kudziko lakunja kudzera mu mawonekedwe achilengedwe onyowa kwambiri omwe amabwera chifukwa cha kuchuluka kwakukulu; amatseka malire a geometry ya malo kudzera mu miyezo yokhwima yapadziko lonse lapansi (monga DIN, ASME, ndi machitidwe ena) ndi njira zowerengera zotsatirika. Ndi chifukwa cha chigoba cholimba ichi chomwe chimaphatikiza kwambiri katundu wakuthupi ndi luso lopanga zinthu zapamwamba kuti njira ya anthu yofufuzira liwiro la kuwala ndi malire a microscopic ikhoza kukhalabe yolimba pakati pa mphepo yamkuntho.
