Mubasa rekugadzira nemazvo uye kuongorora mhando, muchina wekuyera une makonita matatu ndiwo musimboti wekuona kuti chigadzirwa chakarurama. Kururama kwedata rawo rekuyera kunokanganisa zvakananga kunaka kwechigadzirwa uye kugadzirisa maitiro ekugadzira. Zvisinei, kukanganisa kwekushanduka kwekupisa kunokonzerwa nekuchinja kwekupisa panguva yekushanda kwemuchina kwagara kuri dambudziko rakaoma riri kutambudza indasitiri. Hwaro hwegranite, nehunhu hwayo hwakanaka hwemuviri uye zvakanakira zvechimiro, hwave chinhu chikuru chekubvisa kukanganisa kwekushanduka kwekupisa kwemuchina wekuyera une makonita matatu.
Zvikonzero nenjodzi dzezvikanganiso zvekushanduka kwekushisa mumichina yekuyera ine mitsetse mitatu
Kana muchina wekuyera une ma "three-coordinate" uchishanda, injini inomhanya, kupisa kunokonzera kukweshana, uye kuchinja-chinja kwekushisa kwezvakatipoteredza zvinogona kukonzera shanduko mukupisa kwemuchina. Hwaro hwemuchina wekuyera wakagadzirwa nezvinhu zvesimbi zvechinyakare hune "coefficient" yakakwira yekuwedzera kupisa. Semuenzaniso, "coefficient" yekuwedzera kupisa kwesimbi yakajairika inenge 11×10⁻⁶/℃. Kana tembiricha yakwira ne10℃, hwaro hwesimbi hurefu hwemita imwe huchareba ne110μm. Kushanduka uku kudiki kuchaendeswa ku "measuring probe" kuburikidza nechimiro chemuchina, zvichiita kuti nzvimbo yekuyera ichinje uye pakupedzisira zvichikonzera zvikanganiso mudata rekuyera. Mukuongorora zvikamu zvekunyatsojeka, zvakaita se "aero engine blades" uye "precision molds", kukanganisa kwe0.01mm kunogona kutungamira pakusaenderana kwechigadzirwa. Kukanganisa kwekushanduka kwekupisa kunokanganisa zvakanyanya kuvimbika kwekuyera uye kushanda zvakanaka kwekugadzira.
Zvakanakira zvegranite bases
Kuwanda kwemafuta kwakaderera zvakanyanya, chiyero chakagadzikana chekuyera
Granite idombo rechisikigo rinoumbwa kuburikidza nemaitiro e geological kwemazana emamiriyoni emakore. Kuwanda kwayo kwekuwedzera kwekupisa kwakaderera zvikuru, kazhinji kunobva pa (4-8) × 10⁻⁶/℃, inova 1/3 kusvika 1/2 chete yezvinhu zvesimbi. Izvi zvinoreva kuti pasi pekuchinja kwakafanana kwekushisa, shanduko yehukuru hwechigadziko chegranite idiki zvikuru. Kana tembiricha yemhepo ichichinja-chinja, chigadziko chegranite chinogona kuchengetedza chimiro chakasimba chejometri, zvichipa referensi yakasimba yehurongwa hwe coordinate yemuchina wekuyera, kudzivirira kutsauka kwenzvimbo ye probe yekuyera kunokonzerwa nekushanduka kwechigadziko, uye kuderedza kukanganisa kwezvikanganiso zvekushanduka kwekupisa pamhedzisiro yekuyera kubva kumudzi.
Kuomarara kwakanyanya uye chimiro chakafanana kudzvinyirira kutapurirana kwe deformation
Granite yakaoma muchimiro, ine chimiro chekristaro chemukati chakakora uye chakafanana, uye kuoma kwayo kunogona kusvika 6-7 pachikero cheMohs. Kuoma uku kwakanyanya kunoita kuti chigadziko chegranite chisanyanya kukanganiswa ne elastic kana chiine huremu hwemuchina wekuyera pachawo uye simba rekunze panguva yekuyera. Kunyangwe kana mashandiro emuchina achikonzera kudedera kudiki kana simba risina kuenzana remunharaunda, chigadziko chegranite chinogona kudzvinyirira zvinobudirira kutapurirana nekupararira kwedeformation nehunhu hwayo hwakafanana hwechimiro, kudzivirira deformation kubva pachigadziko kuenda kunzira yekuyera, kuve nechokwadi chekuti probe yekuyera inogara iri mumamiriro ekushanda akagadzikana, uye kuvimbisa kururama kwedata rekuyera.
Kushanda kwechisikigo kwekudzivirira, kunotora kudedera nekupisa
Magadzirirwo akasiyana egranite anoita kuti ive nekushanda kwakanaka kwe damping. Kana kudedera kunokonzerwa nekushanda kwemuchina wekuyera kwaendeswa kugranite base, zvicherwa zvemukati uye maburi madiki zvinogona kushandura simba re vibration kuita simba rekupisa uye kurishandisa, zvichikurumidza kuderedza amplitude ye vibration. Panguva iyi, hunhu uhwu hwe damping hunobatsirawo kutora kupisa kunokonzerwa nekushanda kwemidziyo, kuderedza kuunganidzwa uye kupararira kwekushisa pachigadziko, uye kuderedza njodzi yekushanduka kwekupisa kwenzvimbo kunokonzerwa nekupararira kwekushisa kusina kuenzana. Mumabasa ekuyera kwenguva refu, kushanda kwe damping kwegranite base kunogona kuderedza zvakanyanya kuitika kwezvikanganiso zve thermal deformation uye kuwedzera kugadzikana kwekuyera.
Kushandiswa kunoshanda kwechigadziko chegranite
Mushure mekunge mabhizinesi mazhinji ekugadzira atsiva hwaro hwesimbi hwemuchina wekuyera une ma "three-coordinate" nehwaro hwe granite, kurongeka kwekuyera kwakavandudzika zvakanyanya. Mushure mekunge rimwe kambani yekugadzira zvikamu zvemota yaunza muchina wekuyera une ma "three-coordinate" wakashongedzerwa nehwaro hwe granite, kukanganisa kwekuyera kwe "engine block" kwakaderedzwa kubva pa ±15μm yekutanga kusvika mukati me ±5μm. Kudzokororwa uye kudzokororwa kwedata rekuyera kwakavandudzika zvakanyanya, kuvimbika kwekuongorora kwemhando yezvigadzirwa kwakawedzerwa, uye mwero wekusanzwisisana kwechigadzirwa unokonzerwa nekukanganisa kwekuyera wakaderedzwa zvinobudirira. Yakavandudza kushanda zvakanaka kwekugadzira uye kukwikwidzana kwemakambani.
Mukupedzisa, hwaro hwegranite, hune huwandu hwakaderera hwekuwedzera kwekupisa, kuomarara kwakanyanya, chimiro chakafanana uye kushanda zvakanaka kwekudzikisa mvura, hunobvisa kukanganisa kwekushanduka kwekupisa kwemuchina wekuyera une ma "three-coordinate" kubva muzvikamu zvakasiyana-siyana, zvichipa rutsigiro rwakasimba uye rwakavimbika rwekuyera kwakarurama, uye hwave chinhu chakakosha chemidziyo yekuyera yemazuva ano ine ma "high-precision".
