Gutondekanya imiyoboro idafite ibyuma

Umuyoboro w'icyuma udafite icyuho ufite igice cyambukiranya kandi gikoreshwa ku bwinshi nk'umuyoboro wo gutwara amazi, nk'imiyoboro yo gutwara peteroli, gaze gasanzwe, gaze, amazi n'ibikoresho bimwe bikomeye.Umuyoboro wibyuma hamwe nicyuma kizunguruka hamwe nibindi byuma bikomeye, ugereranije nimbaraga zimwe zunamye hamwe na torsion, uburemere bworoshye, nicyuma cyambukiranya ubukungu, gikoreshwa cyane mugukora ibice byubatswe nubukanishi, nkibiti byo gucukura peteroli, ibinyabiziga bitwara ibinyabiziga , amagare yamagare hamwe nubwubatsi bwibyuma bikoreshwa mugukora ibice byimpeta zicyuma, birashobora kunoza imikoreshereze yibikoresho, koroshya uburyo bwo gukora, kubika ibikoresho nigihe cyo gutunganya, byakoreshejwe cyane mugukora imiyoboro yicyuma.

Ibikoresho bya mashini

Ibikoresho bya mashini ni ukwemeza ko ibyuma bikoresha amaherezo (ibikoresho bya mashini) byerekana ibimenyetso byingenzi, biterwa nimiterere yimiti ya sisitemu yo gutunganya ibyuma nubushyuhe.Muburyo bwicyuma gisanzwe, ukurikije ibisabwa bitandukanye byo gukoresha, vuga imitungo ihindagurika (imbaraga zingana, imbaraga zitanga umusaruro cyangwa umusaruro, kuramba) hamwe nubukomezi, ibipimo byerekana ubukana, hari ibyo abakoresha bakeneye kugirango ubushyuhe bwo hejuru kandi buke buke, nibindi.

Strength Imbaraga zingana (σb)
Ibigereranirizo mubitera impagarara, imbaraga ntarengwa (Fb) zihanganye mugihe cyo gukurura, zigabanijwe na stress (σ) zabonetse mukibanza cyambere cyambukiranya igice (So) cyikigereranyo, kizwi nkimbaraga za tensile (σb), igice ni N / mm2 (MPa).Yerekana ubushobozi ntarengwa bwibikoresho byicyuma kugirango birwanye ibyangiritse.Ibiharuro ni
Aho: Fb - imbaraga ntarengwa zikomezwa nicyitegererezo iyo zikuruwe, N (Newton);Noneho - umwimerere wambukiranya igice cyurugero, mm2.

PointIkibanza (σs)
Hamwe numusaruro wibikoresho byibyuma, urugero muburyo bwo kurambura imbaraga ntirwiyongera (guma guma) rushobora gukomeza kurambura imihangayiko, bita umusaruro.Niba kugwa gukomeye bibaye, hagomba gukorwa itandukaniro hagati yumusaruro wo hejuru nu munsi.Igice cy'umusaruro ni N / mm2 (MPa).
Umusaruro wo hejuru (σsu): guhangayikishwa cyane mbere yuko urugero rutanga n'imbaraga zabanje kugwa;ingingo yo hasi yumusaruro (σsl): impagarara nke mugice cyo gutanga umusaruro mugihe ingaruka yambere yinzibacyuho ititaweho.
Inzira yo kubara ingingo yumusaruro ni: formula: Fs - imbaraga zumusaruro (zihoraho) mugihe cyimikorere yikigereranyo, N (Newton) Rero - igice cyambere cyambukiranya igice cyikigereranyo, mm2.

Kurambura nyuma yo kuruhuka (σ)
Mu kizamini gikaze, ijanisha ryiyongera muburebure bwikigereranyo nyuma yo gukurwa kumurongo wacyo kugeza muburebure bwikimenyetso cyambere byitwa kurambura.Byagaragaye nka σ muri%.Kubara nka: formula: L1 - uburebure bwikigereranyo nyuma yo gukuramo ikimenyetso, mm;L0 - uburebure bwikimenyetso cyumwimerere, mm.

Rate Igipimo cyo kugabanya ibice (ψ)
Mu kizamini cya tensile, kugabanuka ntarengwa kwagace kambukiranya agace kagereranijwe kugabanuka nyuma yo gukuramo nkijanisha ryagace kambere kambukiranya igice bita igipimo cyo kugabanuka.Byagaragaye nka ψ muri%.Inzira yo kubara niyi ikurikira
Aho: S0 - umwimerere wambukiranya igice cyikigereranyo, mm2;S1 - agace ntarengwa kambukiranya igice kugabanuka nyuma yikigereranyo gikuweho, mm2.

Index Icyerekezo gikomeye
Ubushobozi bwibikoresho byicyuma cyo kurwanya indentation yikintu gikomeye hejuru, byitwa gukomera.Ukurikije uburyo bwikizamini hamwe nubunini bwakoreshejwe, gukomera birashobora kugabanywa gukomera kwa Brinell, gukomera kwa Rockwell, gukomera kwa Vickers, gukomera kwa Shore, microhardness hamwe nubushyuhe bukabije.Kuri tube ikoreshwa muri rusange kugira Brinell, Rockwell, Vickers gukomera bitatu.

Shandong Xinjie Metal Materials Co., Ltd. , igitutu cyumuvuduko mwinshi, umuyoboro wa peteroli, umuyoboro w’ifumbire mvaruganda, umuyoboro wihariye wibyuma), ibyuma bidafite ingese (umuyoboro wicyuma udafite ingese, umuyoboro wogosha wicyuma, icyuma kitagira umuyonga, icyuma kitagira ibyuma, icyuma cyatumijwe hanze / icyapa, icyuma kizengurutse ibyuma, icyuma kitagira umuyonga Umwanya wa kare kare), ibyuma bidafite umwanda Umwirondoro (I-beam, ibyuma byinguni, ibyuma byumuyoboro) nibindi bicuruzwa.
