Imikorere yikibazo gifatika biterwa nibiranga iyubakwa. Icyifuzo nyamukuru gisabwa kuvangwa nimbaraga zifatika. Ipimwa mu kilo kuri santimetero kare (kg / cm2) cyangwa muri megapaster (mPA). Ukurikije ibyo bipimo, ibikoresho byahawe ikirango (m) hamwe nicyiciro (b).
Mark - byinshi bishaje kuruta amasomo. Muri sima-beto kuvanga, ibirango byinshi, kuva muri M25 hanyuma birangirana na M1000. Ariko mukubaka ibyifuzo kenshi ntabwo birenze icumi. Ikimenyetso gikoreshwa muburyo bwo gutumiza.
Imibare iri mu kiraro ni byinshi, beto irakomeye. Kurugero, M250 ifite imbaraga za 262 kg / cm2, na M350 - 327 kg / cm2.
Icyiciro - cyapimwe muri megalipascals (MPA). Bafite imyaka 21 kuva B3.5 kugeza B80. Ariko, kimwe nibirango, hafi icumi. Iki gitaramo gikoreshwa mubikorwa byumushinga.
Buri kirango gishobora kugereranywa nicyiciro cyihariye naho ubundi.
Kugirango ibyoroshye byikigereranyo hari ameza:
Ikizamini cyo kwikuramo kibaho muri laboratoire hamwe nibikoresho byihariye - Imashini yabanyamakuru. Kugirango umenye icyitegererezo cya beto ikonje muburyo bwa cube cyangwa silinderi ifata. Ingero zifatika zikusanywa kumunsi wa 7 - Nyuma yo gusuka igice, kandi muminsi 28 nyuma yo gusobanukirwa neza. Bashyizwe mu binyamakuru hanyuma bongera buhoro buhoro igitutu kugeza kurimbuka burundu. Agaciro kavuye kuri ecran kandi bizaba imbaraga zo guhagarika.
Hariho kandi ubwoko butaziguye bwubushakashatsi:
- rebound ya elastike;
- ultrasound;
- Uburyo bwo Gutandukana;
- gukubita.
Kimwe nuburyo butandukanye bwo guhuza uburyo.
Ku buryo bwa mbere, imbaraga zo gusubiramo umupira wicyuma uhereye hejuru ya beto ipimwa hakoreshejwe ibikoresho byo gupima: inyundo ya Schmidt cyangwa sclerometero.
Ingingo ku ngingo: Ubwoko bw'ingenzi bw'inkuta ku cyumba
Imbaraga zirasuzumwa ukurikije amakuru azerekana igipimo.
Kuburyo bwa kabiri, metero ulrasound zirakoreshwa. Irashobora kunyuramo hamwe nijwi ridasanzwe. Igipimo cyo gusiga amaherezo gikoreshwa mugihe habaye amahirwe yo kwomekaho mu bundi: urugero, ku nkingi. Hamwe nubu buryo, umuvuduko wo kunyura mu bikoresho bigenwa. Ijwi ryo hejuru ryanditswe mugihe cyamuganda hejuru mumiterere yemetse. Meter ikoreshwa hejuru.
Mugihe cyo kwipimisha, uburyo bwo gutandukanya bupimirwa nimbaraga zijyanye no gutandukanya igice cyibicuruzwa bifatika. Kugirango ukore ibi, kole ya disiki cyangwa shyiramo inanga kandi hamwe na mugenzi wawe uhujwe nigikoresho cyo gupima. Koresha imbaraga ntarengwa zo kurimbuka igice.
Uburyo bw'agaciro bukubiyemo kugereranya ibicapo bisigaye nyuma yo kwigomeka kwa Fidzel cyangwa inyundo ya Kashkarova. Hamwe nubu buryo, fata icyitegererezo nimbaraga zizwi hanyuma usige ikiruhuko kuri cyo ukoresheje igikoresho. Noneho hariho amariba menshi nkiyi hejuru yikintu. Kurangiza gereranya impuzandengo yubujyakuzimu cyangwa diameter yicapiro hamwe nibisanzwe. Ukurikije aya makuru, imbaraga zigenwa.
Guhitamo uburyo bwihariye biterwa nubwoko bwinzego hunganzo hamwe nibishoboka byo kuyobora ibipimo runaka. Iyi ngingo isobanura inzira zibanze gusa, ariko haracyariho guhuza ibitandukanye ushobora gusanga mubipimo byimpaka: gost 10180-90, Gost 1762-2012 na Gost 22690-2015.
