Mbere yo gushyiraimiyoboro isobanutse nezaku isoko, ubushakashatsi bwakozwe n'intoki bugomba gukorwa, kandi uruganda rwacu rukora ibyuma byerekana ibyuma bifite igice cyabigenewe.Kuberako isoko ryibanze ryimyanda isukuye neza ni umwuga wo gupima umwuga.Ariko uyu mwuga ufite ibyangombwa bisabwa cyane kugirango imbaraga zingirakamaro zicyuma gisukuye neza, none nigute dushobora kunoza imbaraga zingutu zumuyoboro wibyuma byuzuye?Noneho reka tubitumenyeshe.
Hejuru yurutonde, imiyoboro isukuye neza irashobora kandi kugeragezwa ukoresheje ibizamini bya eddy aho kugerageza hydraulic.Umuvuduko wubushakashatsi cyangwa eddy yerekana ibipimo byerekana urugero bigomba gukurikiza amategeko ya GB 3092. Imikorere yubukorikori bwicyuma nintego yingenzi yo kwemeza ko ikoreshwa ryanyuma (imikorere yubukanishi), biterwa nibigize imiti nibipimo byo kuvura ubushyuhe bwa ibyuma.Mubipimo byicyuma gisanzwe, ukurikije ibisabwa bitandukanye bisabwa, imikorere yo kurambura (precision galvanised pope pipe tensile strength, umusaruro utanga imbaraga cyangwa umuyoboro wicyuma wa galvanised, kuramba), intego zikomeye hamwe nigihe kirekire, hamwe nubushyuhe bwo hejuru kandi buke busabwa nabakoresha. , Biragaragara.
Icya kabiri, imbaraga zingana zumuringoti wibyuma van σ b) Imbaraga ntarengwa (Fb) ingero zifata mugihe cyimyitozo mugihe cyo kuvunika, zabonetse mubice byambere byambukiranya ibice (So) byikigereranyo （σ ) ， Byitwa imbaraga zingana zumuringoti wibyuma byuzuye （σ b), muri N / mm2 (MPa).Irerekana ubushobozi ntarengwa bwibikoresho byibyuma byo kurwanya ibyangiritse bitewe ningaruka zikomeye.Muri formula: Fb - imbaraga ntarengwa zitwarwa nicyitegererezo mugihe cyo kuvunika, N (Newton);Noneho - Umwimerere wambukiranya igice cyicyitegererezo, mm2.Umuyoboro w'icyuma usobanutse neza: ibikoresho by'icyuma bifite ibintu bitanga umusaruro, hamwe n'imihangayiko urugero rushobora gukomeza kuramba nta kongera imbaraga (kubungabunga umutekano) mugihe cyo kurambura, byitwa umuyoboro w'icyuma wuzuye.Niba imbaraga zigabanutse, hejuru no hepfo ya precision galvanised imiyoboro igomba gutandukanywa.Igice cyicyuma gisukuye neza ni N / mm2 (MPa).Umuyoboro wo hejuru wuzuye neza: Umuvuduko mwinshi mbere yo kugabanuka kwambere kwingufu bitewe no kugonda icyitegererezo;Umuyoboro wo hasi wicyuma cyoroshye: Umuvuduko muke murwego rwo gutanga umusaruro mugihe ingaruka yambere ako kanya itatekerejweho.Muri formula: Fs - imbaraga zunama mugihe cyimyitozo yikigereranyo (gihamye), N (Newton) Rero - umwimerere wambukiranya igice cyikigereranyo, mm2.Kurambura nyuma yo kuvunika: σ σ) Mubigeragezo bikaze, ijanisha ryuburebure ryongewe kuburebure bwa guge nyuma yikimenwa ugereranije nuburebure bwa mbere bwitwa uburebure.
Icya gatatu, hamwe na σ Yerekana ko igice ari%.Muri formula: L1- gupima uburebure bw'icyitegererezo nyuma yo kuvunika, mm;L0- Uburebure bw'umwimerere bw'icyitegererezo, mm.Igipimo cyo kugabanya ibice: （ψ) Mubigeragezo bikaze, kugabanuka kwinshi mubice byambukiranya igice kuri diameter yagabanijwe nyuma yo kumeneka byitwa ijanisha ryagace kambere kambukiranya igice, bita igipimo cyo kugabanya ibice. .hamwe ψ Yerekana ko igice ari%.Muri formula: S0- Umwimerere wambukiranya igice cyicyitegererezo, mm2;S1- Agace ntarengwa kambukiranya igice kuri diameter yagabanutse yikigereranyo nyuma yo kuvunika, mm2.Intego yo gukomera: Ubushobozi bwibikoresho byibyuma byo kurwanya indentation yibintu bikomeye hejuru byitwa gukomera.Ukurikije uburyo butandukanye bwubushakashatsi hamwe nuburyo bukoreshwa, ubukana burashobora kugabanywa mubice bikomeye bya Brinell, ubukana bwa Rockwell, ubukana bwa Vickers, ubukana bwa Shore, microhardness, hamwe nubushyuhe bwo hejuru.Hariho ubwoko butatu bukoreshwa cyane: Brinell, Rockwell, na Vickers gukomera.Ubukomezi bwa Brinell (HB): Ukoresheje umupira wicyuma wa diameter runaka cyangwa umupira ukomeye
