Tensile yekuyedza muchinainoshandiswa zvakanyanya mutete firimu tensile bvunzo, iyo inonyanya kushandiswa kuongorora iyo mechaniki zvivakwa uye deformation kugona kwezvinhu zvakatetepa zvemufirimu mukuita kusimba. Iyi inotevera ongororo yakadzama yeiyo firimu tensile bvunzo yemuchina wekuyedza tensile:
1.Kushanda musimboti
Tensile yekuyedza muchina kuburikidza nemutongi, iyo yekumhanya yekudzora sisitimu yekudzora servo mota kutenderera, yakaderedzwa neiyo deceleration system kuburikidza neiyo chaiyo screw pair kutyaira danda kumusoro kana pasi, kuitira kuti iite kushushikana pamuenzaniso wefirimu. Munguva yekusimba kwemaitiro, iyo sensor sensor inoyera kukosha kwekusimba munguva chaiyo, uye shanduko yesimba rekusimba uye sampuli yekuwedzera urefu inorekodhwa neiyo data yekutora system. Chekupedzisira, kuburikidza neiyo data yekuongorora software kugadzirisa iyo data yakarekodhwa, iyo firimu tensile simba, kurebesa uye zvimwe zviratidzo zvekuita.
2.Test matanho
Gadzirira muenzaniso: Shandisa chishandiso chakakosha kutema sampu ine rectangular kubva kune iyo firimu zvinhu kuti isangane nezvinodiwa, kuve nechokwadi chekuti saizi yemuenzaniso yakakodzera uye mupendero hauna kukuvara.
Batanidza sampuli: Isa migumo yese yesample mune yekumisikidza yemuchina wekuyedza, uye gadzirisa chigadziriso kuti uve nechokwadi chekuti sampu yakabatwa zvakasimba uye yakarongeka.
Seta bvunzo paramita: isa preloading simba, tensile kumhanya uye mamwe ma paramita zvinoenderana nebvunzo zvinodiwa.
Tanga kutambanudza: Tanga iyo tensile yekuyedza muchina uye zvishoma nezvishoma isa tension kuitira kuti sampuli iwedzere munzira yekusimba.
Kurekodha dhata: Panguva yekudhirowa, shanduko yesimba rekusimba uye sampuli yekuwedzera urefu inorekodhwa munguva chaiyo.
Specimen fracture: Ramba uchitambanudza muenzaniso kusvika waputsika, rekodha simba guru rekugadzirisa uye kureba kwekureba kwekuputsika panguva yekuputsika.
Ongororo yedata: Iyo data yakarekodwa inogadziriswa uye kuongororwa kuti iwane kusimba kwesimba, kurebesa uye zvimwe zvinongedzo zvekuita zvefirimu.
3.Common test nzira
Longitudinal tensile bvunzo: iyo huru yekuyedza firimu mune iyo longitudinal kutungamira kwesimba rekusimba, kureba uye zvimwe zviratidzo zvekuita.
Transverse tensile bvunzo: yakafanana neyo longitudinal tensile bvunzo, asi kunyanya inoyedza iyo tensile zvimiro zvefirimu munzira inochinjika.
Muedzo wekubvarura: edza simba rekubvarura uye kubvarura kurebesa kwefirimu, nekuisa kushushikana kuti firimu ribvambuke pane imwe kubvarura Angle.
Dzimwe nzira dzekuyedza: senge kukanganisa bvunzo, friction coefficient test, nezvimwewo, nzira dzekuyedza dzakakodzera dzinogona kusarudzwa zvinoenderana nezvinodiwa.
4. Chikamu chekushandiswa
Tensile yekuyedza muchina firimu tensile bvunzo inoshandiswa zvakanyanya muwaya netambo, zvekuvakisa, aerospace, kugadzira michina, rabha mapurasitiki, machira, midziyo yemumba uye mamwe maindasitiri ekuongorora uye kuongorora zvinhu. Panguva imwecheteyo, ndiyo yakanakira bvunzo midziyo yesainzi yekutsvagisa masangano, makoreji nemayunivhesiti, maindasitiri nemabhizinesi emigodhi, tekinoroji manejimendi, commodity inspection arbitration uye mamwe madhipatimendi.
5. Test standards
Firimu tensile yekuyedza muchina mufirimu tensile bvunzo, inofanirwa kutevedzera akakodzera nyika nepasirese mwero, senge GB/T 1040.3-2006 "purasitiki tensile zvimiro zvekutemerwa kweChikamu 3: firimu uye wafer bvunzo mamiriro" zvichingodaro. Aya mazinga anotsanangura zvinodikanwa zvemamiriro ebvunzo, gadziriro yemuenzaniso, nhanho dzebvunzo, kugadzirisa data, nezvimwe, kuve nechokwadi chechokwadi uye kuvimbika kwemhedzisiro yebvunzo.
