Crack Hisha? Koresha IR Ishusho ya Granite Thermo-Stress Isesengura

Kuri ZHHIMG®, tuzobereye mugukora granite ibice bifite nanometero neza. Ariko ibisobanuro nyabyo birenze ibirenze kwihanganira inganda; ikubiyemo uburebure bwigihe kirekire bwuburinganire nuburambe bwibintu ubwabyo. Granite, yaba ikoreshwa mumashini isobanutse neza cyangwa iyubakwa rinini, irashobora kwibasirwa nudusembwa twimbere nka micro-cracks nubusa. Uku kudatungana, hamwe no guhangayikishwa nubushyuhe bwibidukikije, byerekana mu buryo butaziguye kuramba hamwe n’umutekano.

Ibi bisaba isuzuma ryateye imbere, ridatera. Amashusho ya Thermal Infrared (IR) yagaragaye nkuburyo bukomeye bwo gupima (NDT) bwa granite, butanga uburyo bwihuse, budahuza kugirango busuzume ubuzima bwimbere. Hamwe na Analyse ya Thermo-Stress Isesengura, turashobora kurenga gusa kubona inenge kugirango twumve neza ingaruka zayo muburyo butajegajega.

Ubumenyi bwo Kubona Ubushyuhe: Amahame yo Kwerekana IR

Amashusho ya Thermal IR akora mugutwara ingufu za infragre ziva hejuru ya granite hanyuma ukayihindura ikarita yubushyuhe. Ikwirakwizwa ry'ubushyuhe ryerekana mu buryo butaziguye imiterere ya thermophysical.

Ihame riroroshye: inenge zimbere zikora nka anomalie yumuriro. Kumeneka cyangwa ubusa, kurugero, bibuza umuvuduko wubushyuhe, bigatera itandukaniro rigaragara mubushyuhe buturutse kumajwi akikije. Igice gishobora kugaragara nkumurongo ukonje (uhagarika ubushyuhe bwubushyuhe), mugihe akarere gakomeye cyane, kubera itandukaniro ryubushobozi bwubushyuhe, karashobora kwerekana ahantu hashyushye.

Ugereranije nubuhanga busanzwe bwa NDT nka ultrasonic cyangwa X-ray igenzura, amashusho ya IR atanga ibyiza bitandukanye:

• Kwihuta, Kinini-Gusikana: Ishusho imwe irashobora gukora metero kare, bigatuma biba byiza mugusuzuma byihuse ibice binini bya granite, nkibiti byikiraro cyangwa ibitanda byimashini.
• Kudahuza no kudahuza: Uburyo ntibusaba guhuza umubiri cyangwa uburyo bwo guhuza amakuru, byemeza ko zeru zangiritse zangirika hejuru yubuso bwibigize.
• Igenzura rya Dynamic: Itanga igihe-nyacyo cyo gufata igihe cyo guhindura ubushyuhe, nibyingenzi kugirango hamenyekane inenge ziterwa nubushuhe uko zitera imbere.

Gufungura Mechanism: Theory of Thermo-Stress

Ibice bya Granite byanze bikunze biteza imbere ubushyuhe bwimbere bitewe nubushyuhe bwibidukikije cyangwa imitwaro yo hanze. Ibi bigengwa namahame ya thermoelasticité:

• Kwagura Ubushyuhe Bidahuye: Granite ni urutare rugizwe. Ibyiciro byimbere byimbere (nka feldspar na quartz) bifite coefficient zitandukanye zo kwagura ubushyuhe. Iyo ubushyuhe buhindutse, uku kudahuza kuganisha ku kwaguka kudahuje, kurema uturere twinshi twinshi cyangwa guhangayika.
• Ingaruka zo Kubuza Inenge: Inenge nk'imvune cyangwa imyenge isanzwe ibuza kurekura imihangayiko yaho, itera guhangayika cyane mubintu byegeranye. Ibi bikora nka yihuta yo gukwirakwiza.

Ibigereranyo bitari bike, nka Finite Element Analysis (FEA), nibyingenzi mukugereranya iyi ngaruka. Kurugero, munsi yubushyuhe bwikigereranyo bwa 20 ° C (nkumunsi usanzwe wumunsi / nijoro), icyapa cya granite kirimo igikonjo gihagaritse gishobora guhura nuburemere bukabije bugera kuri MPa 15. Urebye ko imbaraga za granite zidakabije akenshi ziri munsi ya MPa 10, iyi mitekerereze irashobora gutuma igikoma gikura mugihe, bigatuma habaho kwangirika kwimiterere.

Ubwubatsi mubikorwa: Inyigo yo Kubungabunga

Mu mushinga wo gusana vuba aha werekeye inkingi ya granite ya kera, amashusho ya IR yerekana ubushyuhe bwerekanye neza ubukonje butunguranye buri mwaka mugice cyo hagati. Imyitozo yakurikiyeho yemeje ko iyi anomaly ari imbere ya horizontal imbere.

Ubundi kwerekana imiterere ya thermo-stress yatangijwe. Ikigereranyo cyerekanye ko impagarara zikaze mu gihe cy'ubushyuhe bwo mu cyi zigeze kuri MPa 12, bikarenga urugero rw'ibikoresho. Igisubizo gikenewe cyari inshinge epoxy resin inshinge kugirango ihagarike imiterere. Igenzura ryakozwe nyuma yo gusana ryemeje umurima wubushyuhe buringaniye, kandi kwigana impungenge byemeje ko ubushyuhe bwumuriro bwaragabanutse kugera kumutekano (munsi ya 5 MPa).

Horizon yo gukurikirana ubuzima bwiza

Amashusho ya Thermal IR, afatanije nisesengura rikomeye, atanga inzira ya tekiniki ikora kandi yizewe yo kugenzura ubuzima bwubuzima (SHM) bwibikorwa remezo bikomeye bya granite.

Ejo hazaza hubu buryo bwerekanwe kwizerwa no kwikora:

1. Multi-Modal Fusion: Guhuza amakuru ya IR hamwe na test ya ultrasonic kugirango tunonosore ubwinshi bwimiterere yuburebure bwinenge no gusuzuma ingano.
2. Isuzuma ryubwenge: Gutezimbere-byimbitse-algorithms kugirango ihuze imirima yubushyuhe hamwe nimirima yigana, ituma ibyiciro byikora byikora kandi bigasuzuma ingaruka zishobora gutegurwa.
3. Dynamic IoT Sisitemu: Guhuza ibyuma bya IR hamwe na tekinoroji ya IoT yo kugenzura-igihe nyacyo cyo kugenzura imiterere yubushyuhe nubukanishi muburyo bunini bwa granite.

Mu kudahwema kumenya inenge zimbere no kugereranya ingaruka ziterwa nubushyuhe bwumuriro, ubu buryo bwateye imbere bwongerera igihe ubuzima bwigihe cyose, butanga ubumenyi bwa siyansi kubungabunga umurage n’umutekano w’ibikorwa remezo.
