Tijaabiyaha adkaanta guud (Tijaabiyaha adkaanta ee Brinell Rockwell Vickers)

Tijaabiyaha adkaanta Universal dhab ahaantii waa qalab tijaabo oo dhammaystiran oo ku salaysan heerarka ISO iyo ASTM, taasoo u oggolaanaysa isticmaalayaasha inay sameeyaan tijaabooyinka adkaanta Rockwell, Vickers iyo Brinell isla qalabka. Tijaabiyaha adkaanta Universal waxaa lagu tijaabiyaa iyadoo lagu saleynayo mabaadi'da Rockwell, Brinell, iyo Vickers halkii laga isticmaali lahaa xiriirka beddelka ee nidaamka adkaanta si loo helo qiimayaal adag oo badan.

Miisaanka adag ee HB Brinell wuxuu ku habboon yahay cabbiraadda adkaanta birta la shubay, biraha aan birta ahayn, iyo biraha kala duwan ee la dahaadhay iyo kuwa la hagaajiyay. Kuma habboona cabbiraadda muunadaha ama shaqooyinka aad u adag, aad u yar, aad u khafiifsan, oo aan u oggolaanayn in la jeexo meelaha waaweyn.

Miisaanka adag ee HR Rockwell wuxuu ku habboon yahay: tijaabinta caaryada, cabbirka adkaanta ee qaybaha la damiyay, la damiyay iyo kuwa la kululeeyay ee kulaylka lagu daweeyay.

Cabbirka adag ee HV Vickers wuxuu ku habboon yahay: cabbiraadda adkaanta muunadaha iyo qaybaha leh meelo yaryar iyo qiimayaal adag oo sarreeya, adkaanta lakabyada ama dahaarka la dhex geliyay ka dib daawaynta dusha sare ee kala duwan, iyo adkaanta walxaha khafiifka ah.

Soo socda waa hordhac ku saabsan taxanaha cusub ee tijaabiyeyaasha adkaanta ee Universal: iyo shaashadda taabashada Tijaabada adkaanta ee Universal

Si ka duwan tijaabiyaha adag ee Universal-ka ee caadiga ah, jiilka cusub ee tijaabiyaha adag ee Universal wuxuu adeegsadaa tignoolajiyada dareemayaasha xoogga iyo nidaamka jawaab celinta xoogga loo yaqaan 'closed-loop force response' si uu u beddelo qaabka culayska rarista, taasoo ka dhigaysa cabbirka mid fudud oo qiimaha la cabbiray mid deggan.
