Amakuru

Nkigice cyingenzi cyibikoresho byo gupima ibikoresho, ibizamini bya tensile bigira uruhare runini mubikorwa byo gukora inganda, ubushakashatsi bwibikoresho niterambere, nibindi, ariko, amakosa amwe amwe azagira ingaruka zikomeye kumyizerere y'ibizamini. Wabonye ibisobanuro birambuye?

1.Imbaraga za sensor ntabwo zihuye n'ibisabwa:

Imbaraga sensor ningingo yingenzi mugupima kwinshi, kandi guhitamo imbaraga zikoreshwa ni ngombwa. Amwe mumakosa akunze kuboneka harimo: kudahindura imbaraga za sensor, gukoresha sensor yingufu hamwe nintera idakwiye, no gusaza imbaraga za sensor kugirango bitere kunanirwa.

Igisubizo:

Ibintu bikurikira bigomba kwitabwaho muguhitamo sensor ikenewe cyane ukurikije icyitegererezo:

1. Imbaraga za sensor urwego:
Menya imbaraga zisabwa sensor urwego rushingiye kumubare ntarengwa nimbaraga ntoya yibisubizo bisabwa kubizamini byawe. Kurugero, kuburugero rwa plastike, niba imbaraga zombi zingana na modulus bigomba gupimwa, birakenewe ko dusuzuma byimazeyo imbaraga zingaruka zibi bisubizo byombi kugirango uhitemo imbaraga zikwiye.

2. Urutonde rwukuri kandi rwukuri:

Urwego rusanzwe rwukuri rwimbaraga ni 0.5 na 1. Dufashe 0.5 nkurugero, mubisanzwe bivuze ko ikosa ntarengwa ryemerewe na sisitemu yo gupima riri muri ± 0.5% byagaciro kerekanwe, ntabwo ± 0.5% byurwego rwuzuye. Ni ngombwa gutandukanya ibi.

Kurugero, kuri 100N sensor sensor, mugihe upimye 1N imbaraga zingirakamaro, ± 0.5% byagaciro kerekanwe ni ± 0.005N ikosa, mugihe ± 0.5% yikigereranyo cyose ni ± 0.5N ikosa.
Kugira ubunyangamugayo ntibisobanura ko urwego rwose rufite uburinganire bumwe. Hagomba kubaho imipaka yo hasi. Muri iki gihe, biterwa nurwego rwukuri.
Dufashe sisitemu zitandukanye zo kwipimisha nkurugero, ibyuma bikurikirana bya UP2001 & UP-2003 birashobora guhuza ibipimo 0,5 kurwego kuva byuzuye kugeza 1/1000 byuzuye.

Ibikoresho ntibikwiye cyangwa imikorere ni bibi:
Ibikoresho ni uburyo bwo guhuza imbaraga sensor hamwe nicyitegererezo. Nigute ushobora guhitamo ibice bizagira ingaruka kuburyo butaziguye kandi bwizewe bwikizamini. Uhereye kubigeragezo, ibibazo nyamukuru biterwa no gukoresha ibikoresho bidakwiye cyangwa imikorere mibi ni kunyerera cyangwa kuvunika.

Kunyerera:

Kugaragara cyane kunyerera ni urugero rusohoka ruvuye murwego cyangwa ihindagurika ridasanzwe ryumurongo. Byongeye kandi, irashobora kandi gucirwaho iteka mugushira akamenyetso hafi yikibanza cyo gufunga mbere yikizamini kugirango harebwe niba umurongo wikimenyetso uri kure yubuso bufatanye, cyangwa niba hari ikimenyetso cyo gukurura ku menyo yinyo yikigereranyo.

Igisubizo:

Iyo habonetse kunyerera, banza wemeze niba clamp y'intoki ikomezwa mugihe ufashe icyitegererezo, niba umuvuduko wumwuka wumuyaga wa pneumatike ari munini bihagije, kandi niba uburebure bwikigereranyo bwicyitegererezo buhagije.
Niba ntakibazo kijyanye nigikorwa, tekereza niba guhitamo clamp cyangwa clamp guhitamo bikwiye. Kurugero, isahani yicyuma igomba kugeragezwa hamwe na clamp yisanzuye aho kuba isura ya clamp yoroheje, na reberi ifite deformasiyo nini igomba gukoresha kwifungisha cyangwa kwifata pneumatike aho gukoresha intoki.

Kumena urwasaya:
Igisubizo:

Urwasaya ntangarugero ruvunika, nkuko izina ribivuga, kumena aho ufata. Bisa no kunyerera, birakenewe kwemeza niba igitutu cyo gufatira ku cyitegererezo ari kinini cyane, niba hejuru ya clamp cyangwa urwasaya byatoranijwe uko bikwiye, nibindi.
Kurugero, mugihe ukora ikizamini cyumugozi, umuvuduko ukabije wumwuka uzatera ingero kumeneka, bikavamo imbaraga nke no kuramba; mugupima firime, urwasaya rwometseho reberi cyangwa urwasaya rwihuza insinga bigomba gukoreshwa aho kuba urwasaya rwerekanwe kugirango wirinde kwangiza urugero no gutera kunanirwa hakiri kare.

3. Imizigo idahuye:

Guhuza urunigi rw'imizigo birashobora kumvikana gusa nkaho imirongo yo hagati yingufu za sensor, fixture, adapt hamwe nicyitegererezo biri kumurongo ugororotse. Mu igeragezwa ryinshi, niba guhuza urunigi rw'imizigo atari byiza, icyitegererezo cyikizamini kizakoreshwa izindi mbaraga zo gutandukana mugihe cyo gupakira, bikavamo imbaraga zingana kandi bigira ingaruka kumyizerere y'ibisubizo.

Igisubizo:

Mbere yuko ikizamini gitangira, guhuza urunigi rw'imizigo bitari urugero bigomba kugenzurwa no guhinduka. Igihe cyose icyitegererezo gifatanye, witondere guhuza hagati yikigereranyo cya geometrike yikigereranyo hamwe nu mutwaro wo kwikorera urunigi. Urashobora guhitamo ubugari bwa clamping hafi yubugari bwa clamping ubugari, cyangwa ugashyiraho igikoresho cyibanze kugirango byorohereze imyanya kandi bitezimbere gusubiramo.

4. Guhitamo nabi no gukora nabi inkomoko:

Ibikoresho bizahinduka mugihe cyo kwipimisha. Amakosa akunze gupimwa (deformasiyo) harimo guhitamo nabi inkomoko yo gupima ibintu, guhitamo bidakwiye kwaguka, kwishyiriraho nabi kwa extensometero, kalibrasi idahwitse, nibindi.

Igisubizo:

Guhitamo inkomoko yisoko ishingiye kuri geometrie yikigereranyo, ingano ya deformasiyo, nibisubizo bisabwa.
Kurugero, niba ushaka gupima modulus ya plastiki nicyuma, gukoresha ibipimo byo kwimura ibiti bizavamo ibisubizo bike bya modulus. Muri iki gihe, ugomba gusuzuma urugero rw'uburebure bwa metero hamwe na stroke isabwa kugirango uhitemo extensometero ikwiye.

Kubice birebire bya file, imigozi nibindi bigereranyo, kwimura ibiti birashobora gukoreshwa mugupima uburebure bwabyo. Haba ukoresheje igiti cyangwa umugozi, ni ngombwa cyane kwemeza ko ikadiri na extensometero byapimwe mbere yo gukora ikizamini gikomeye.

Mugihe kimwe, menya neza ko extensometero yashyizweho neza. Ntigomba kuba irekuye cyane, itera kwaguka kunyerera mugihe cyikizamini, cyangwa gukomera cyane, bigatuma icyitegererezo kimeneka ku cyuma cyagutse.

5.Ibihe bidasanzwe byo gutoranya:

Ibyatanzwe byerekana inshuro nyinshi birengagizwa. Inshuro ntoya irashobora gutera igihombo cyibizamini byingenzi kandi bikagira ingaruka kubisubizo. Kurugero, niba imbaraga nyazo zidakusanyirijwe hamwe, ibisubizo ntarengwa bizaba bike. Niba icyitegererezo cyinshyi ari kinini cyane, bizaba birenze urugero, bikavamo kutongera amakuru.

Igisubizo:

Hitamo icyitegererezo gikwiye gishingiye kubisabwa n'ibizamini. Amategeko rusange nugukoresha 50Hz y'icyitegererezo. Ariko, kugirango bihindurwe byihuse, indangagaciro yo hejuru igomba gukoreshwa kugirango yandike amakuru.

6. Amakosa yo gupima ibipimo:

Ibipimo byo gupima ibipimo birimo kutapima ingano yicyitegererezo nyacyo, gupima amakosa yimyanya, gupima amakosa yibikoresho, hamwe namakosa yinjiza.

Igisubizo:

Mugihe cyo kwipimisha, ingano yikigereranyo ntigomba gukoreshwa muburyo butaziguye, ariko ibipimo nyabyo bigomba gukorwa, bitabaye ibyo guhangayika bishobora kuba bike cyangwa hejuru cyane.

Ubwoko butandukanye bwikigereranyo hamwe nubunini buringaniye bisaba ibizamini bitandukanye byo guhuza ibizamini hamwe nukuri kubikoresho bipima ibipimo.

Icyitegererezo gikenera gupima ibipimo byahantu henshi kugirango ugereranye cyangwa ufate agaciro gake. Witondere cyane gufata amajwi, kubara no kwinjiza inzira kugirango wirinde amakosa. Birasabwa gukoresha igikoresho gipima ibipimo byikora, kandi ibipimo byapimwe bihita byinjira muri software kandi bikabarwa mu mibare kugirango wirinde amakosa yo gukora no kunoza imikorere yikizamini.

7. Ikosa ryo gushiraho software:

Gusa kuba ibyuma ari byiza ntabwo bivuze ko ibisubizo byanyuma aribyo. Ibipimo bifatika kubikoresho bitandukanye bizaba bifite ibisobanuro byihariye n'amabwiriza y'ibizamini kubisubizo by'ibizamini.

Igenamiterere muri software rigomba gushingira kuri ibyo bisobanuro hamwe namabwiriza yuburyo bwo kugerageza, nka preloading, igipimo cyibizamini, guhitamo ubwoko bwo kubara hamwe nibisobanuro byihariye.

Usibye amakosa yavuzwe haruguru ajyanye na sisitemu yikizamini, gutegura ingero, ibidukikije byikizamini, nibindi nabyo bigira ingaruka zikomeye kubizamini bya tensile kandi bigomba kwitabwaho.
