Umwanya wo gusaba
Ikoreshwa cyane cyane mukumenya imikorere ya creep nimbaraga zo kwihanganira ibikoresho byicyuma munsi yubushyuhe runaka nuburemere burigihe mugihe cyagenwe.
Shyira mu bikorwa ibipimo bisanzwe GB / T2039-1997 "Metal Tensile Creep and Testurance Test Method", JJG276-88 "Amabwiriza yo Kugenzura Ubushyuhe bwo hejuru hamwe n’imashini yipimisha kwihangana".
Ibintu by'ingenzi
Ibisobanuro bisanzwe byerekana ubushyuhe bwo hejuru hamwe nimashini yipimisha imbaraga zo kwihangana bikoreshwa mukumenya ubushyuhe bwo hejuru hamwe nimbaraga zo kwihanganira imikorere yibikoresho byicyuma mubihe byubushyuhe buhoraho hamwe nimbaraga zihoraho mubyerekezo byicyitegererezo.
Ibiranga tekinike
Shiraho ibikoresho bijyanye kugirango ubigereho:
(1) Ikigereranyo cyo kwihanganira ubushyuhe bwo hejuru:
A. Bifite ibikoresho byo gupima ubushyuhe bwo hejuru hamwe na sisitemu yo kugenzura ubushyuhe,
B. Bifite ibikoresho byo gukurura burundu (clamp ntangarugero),
C. Imbaraga zirambye zibikoresho zishobora gupimwa munsi yubushyuhe burigihe nuburemere burigihe.
(2) Ikizamini cyo hejuru yubushyuhe:
A, ifite ibikoresho byo gupima ubushyuhe bwo hejuru hamwe na sisitemu yo kugenzura ubushyuhe,
B, ifite ubushyuhe bwo hejuru bwo gukurura inkoni (sample fixture)
C, ifite ibikoresho bya creep extensometero (igikoresho cyo gushushanya deformasiyo)
D, ifite ibikoresho byo gupima ibimera (igikoresho cyo gupima deformasiyo).
Imiterere yibikoresho irashobora gupimwa munsi yubushyuhe burigihe hamwe nuburemere burigihe.
