Muchina wemagetsi wekuyedza wepasirese wakanyanya kukodzera kuyedza simbi uye isiri-simbi zvinhu, zvakaita serabha, mapurasitiki, waya netambo, tambo dzefiber optic, mabhandi ekuchengetedza, bhandi rinoumbwa zvinhu, profiles epurasitiki, mipumburu isina mvura, pombi dzesimbi, mbiri yemhangura, chitubu simbi, inotakura simbi, simbi isina tsvina (senge yakakwira kuomarara kwendiro, simbi isina waya). Inoshandiswa kutambanudza, kudzvanya, kukotama, kucheka, kusvuura kubvarura mapoinzi maviri (inoda extensometer) uye mimwe miedzo. Muchina uyu unotora dhizaini yakabatanidzwa yemagetsi, inonyanya kuumbwa nemagetsi masensa, transmitters, microprocessors, mitoro yekutyaira michina, makomputa, uye mavara inkjet printer. Iyo ine yakakura uye yakaringana kurodha kumhanya uye simba kuyerwa renji, uye ine yakakwirira kurongeka uye senits mukuyera uye kudzora mitoro uye kutamiswa. Inogonawo kuita otomatiki kudzora kuyedza yekugara ichirodha uye inogara ichitama. Iyo yepasi yakamira modhi, dhizaini, uye pendi zvinonyatso funga misimboti yakakodzera yemazuva ano maindasitiri dhizaini uye ergonomics.
Zvinhu zvinokanganisa kushanda kwemagetsi universal test machines:
1, Host chikamu
Kana kuiswa kweinjini huru isiri nhanho, zvinokonzeresa kupesana pakati pepiston inoshanda uye cylinder madziro ekushanda, zvichikonzera kukanganisa. Kazhinji inoratidzwa seyakanaka kusiyana, uye sezvo mutoro unowedzera, kukanganisa kunoguma kunoderera zvishoma nezvishoma.
2, Dynamometer chikamu
Kana kuiswa kwegeji yesimba kusiri nhanho, zvinokonzeresa kupokana pakati pemabhengi ekutenderera shaft, ayo anowanzo kushandurwa kuita mutsauko wakashata.
Mhando mbiri dziri pamusoro dzemhosho dzine simba rakati kurei pazviyero zvidiki zvemutoro uye kukanganiswa kudiki pazviyero zvakakura zvemutoro.
Mhinduro
1. Chekutanga, tarisa kana kuiswa kwemuchina wekuyedza kwakatwasuka. Shandisa furemu nhanho kuyera injini huru mumativi maviri perpendicular kune imwe neimwe mhete yekunze yehumburumbira yeoiri inoshanda (kana koramu).
2.Gadzirisa chiyero chegeji yesimba pamberi petsvimbo yekuzunungusa, gadzirisa uye gadzirisa mucheto wekuzununguka nemutsara wakavezwa wemukati, uye shandisa nhanho kugadzirisa nhanho dzekuruboshwe nedzorudyi dzomuviri kurwisana nedivi retsvimbo.
Izvo zvakakosha zvinoedzwa zvinhu zvemagetsi universal yekuyedza michina:
Zvinhu zvekuyedza zvemagetsi tensile yekuyedza michina zvinogona kukamurwa kuita zvakajairwa kuyedza zvinhu uye zvakakosha zvinhu zvekuyedza. Kuti uone iyo coefficient yekuomarara kwezvinhu, iyo yakakwira chiyero cheyakajairwa kushushikana chikamu muchikamu chimwe chete kune yakajairika strain, iyo yakasimba uye yakawanda ductile zvinhu.
① Zvakajairwa kuyedza zvinhu zvemagetsi tensile yekuyedza michina: (yakajairika kuratidza kukosha uye yakaverengerwa kukosha)
1. Kushushikana mupfungwa, kusimba simba, kusimba, uye kureba panguva yekuzorora.
2. Constant tensile stress; Constant stress elongation; Kugara kushushikana kukosha, kubvarura simba, kukosha kwekumanikidza chero nguva, kureba chero nguva.
3. Simba rekudhonza, simba rekunamatira, uye peak kukosha kuverenga.
4. Muedzo wepressure, shear peeling force test, bending test, pull-out force puncture force test.
② Zvinhu zvakakosha zvekuyedza zvemagetsi tensile yekuyedza michina:
1. Kushanda elasticity uye hysteresis kurasikirwa: Pamuchina wemagetsi universal test machine, kana sampuli yakatambanudzwa pane imwe sipidhi kune imwe elongation kana kune imwe mutoro wakatarwa, chikamu chebasa rakadzorerwa panguva yekumisikidza uye kupedzwa panguva yekuwedzera inoyerwa, inova iyo elasticity inoshanda; Iyo muzana yesimba rakarasika panguva yekurebesa uye kudonhedzwa kwemuenzaniso uchienzaniswa nebasa rinodyiwa panguva yekurebesa kunonzi kurasikirwa kwe hysteresis.
2. Chitubu K kukosha: Chiyereso chechikamu chesimba muchikamu chakafanana seye deformation kune deformation.
3. Simba rezvibereko: The quotient yakawanikwa nekuparadzanisa mutoro apo kureba kwechigarire kunosvika kune imwe nzvimbo inokosha panguva yekushungurudzika neyokutanga-chikamu chechikamu chechikamu chakafanana.
4. Goho repfungwa: Kana zvinhu zvakatambanudzwa, deformation inowedzera nokukurumidza apo kushungurudzika kunoramba kuripo, uye iyi pfungwa inonzi goho. Nzvimbo yegoho yakakamurwa kuva mapoinzi epamusoro neakaderera, uye kazhinji goho riri pamusoro rinoshandiswa senzvimbo yegoho. Kana mutoro ukapfuura muganhu wakaenzana uye usingachaenzani nekurebesa, mutoro unozoerekana wadzikira, wobva wachinja nekudzika nekufamba kwenguva, zvichikonzera shanduko huru mukurebesa. Chiitiko ichi chinodaidzwa kuti kubereka.
5. Permanent deformation: Mushure mokubvisa mutoro, zvinyorwa zvichiri kuchengetedza deformation.
6. Elastic deformation: Mushure mokubvisa mutoro, deformation yezvinhu zvinopera zvachose.
7. Elastic muganho: Iyo yakanyanya kushushikana iyo chinhu chinogona kumira pasina deformation zvachose.
8. Muganho wakaenzana: Mukati mehumwe mutsara, mutoro unogona kuchengetedza hukama hwakaenzana nekurebesa, uye kushushikana kwayo kwakanyanya ndiyo muganhu wakaenzana.
9. Coefficient of elasticity, inozivikanwawo seYoung's modulus ye elasticity.
