Inkambu yohlelo lokusebenza
Ngokuyinhloko isetshenziselwa ukunquma ukusebenza kwe-creep namandla okukhuthazela ezinto zensimbi ngaphansi kwezinga lokushisa elithile nomthwalo oqhubekayo phakathi nesikhathi esinqunyiwe.
Sebenzisa i-GB/T2039-1997 ejwayelekile "I-Metal Tensile Creep and Endurance Test Method", JJG276-88 "Imithetho Yokuqinisekisa Yomshini Wokuhlola I-High Temperature Creep and Endurance Strength".
Izici Eziyinhloko
Incazelo ejwayelekile yomshini wokuhlola amazinga okushisa aphezulu kanye nokuqina kokuqina isetshenziselwa ukunquma ukukhuphuka kwezinga lokushisa okuphezulu nokusebenza kwamandla okukhuthazela kwezinto zensimbi ngaphansi kwezimo zokushisa okungaguquki namandla aqinile aqinile ekuqondeni kwe-axial yesampula.
Izici Zobuchwepheshe
Lungiselela izesekeli ezihambisanayo ukuze uzuze:
(1) Ukuhlolwa kwamandla okubekezelela izinga lokushisa eliphezulu:
A. Ifakwe idivayisi yokuhlola izinga lokushisa eliphezulu kanye nesistimu yokulawula izinga lokushisa,
B. Ifakwe induku yokudonsa ehlala njalo (i-specimen clamp),
C. Amandla aqinile wezinto ezibonakalayo angalinganiswa ngaphansi kwesenzo sokushisa okungaguquki kanye nomthwalo oqinile oqinile.
(2) Ukuhlolwa kwezinga lokushisa eliphezulu:
A, ifakwe idivayisi yokuhlola izinga lokushisa eliphezulu kanye nesistimu yokulawula izinga lokushisa,
B, ifakwe izinga lokushisa eliphezulu lokudonsa induku (isampula yokulungisa)
C, ifakwe i-creep extensometer (idivayisi yokudweba i-deformation)
D, ifakwe insimbi yokulinganisa ehambayo (ithuluzi lokulinganisa ukuguquguquka).
Izakhiwo ezinyakazayo zezinto zokwakha zingalinganiswa ngaphansi kwezinga lokushisa elingashintshi kanye nomthwalo oqinile oqinile.
