Iyo inonyanya kushandiswa kuona iyo creep performance uye kutsungirira simba rezvishandiso zvesimbi pasi peimwe tembiricha uye nguva dzose mutoro mukati menguva yakatarwa.

Tsanangudzo yakajairwa yeiyo yakakwira tembiricha uye yekutsungirira yekutsungirira kwekuedzwa kwekutsungirira inoshandiswa kuona tembiricha yakakwira yekushisa kwemamiriro ezvinhu esimbi pasi pemamiriro ezvinhu ekupisa uye anogara akasvinura muitiro weiyo nzira yeiyo sampuli yemuenzaniso.
Maitiro ehunyanzvi
Gadzirisa zvinhu zvinoenderana kuti uwane:
(1) Tembiricha yakakwira ichipedzisira kutsungirira bvunzo bvunzo:
A. Yakashongedzwa neyakawandisa tembiricha bvunzo uye tembiricha yekudzora system,
B. Yakashongedzwa neLightent Dhirowa tsvimbo (fungidziro Clamp),
C. Simba rinogara riripo yezvinyorwa rinogona kuyerwa pasi pechiitiko chekugara tichidziya uye kugara zvakanaka.
(2) kupisa kwakanyanya kwekutenderera kwechiedza:
A, yakagadzirirwa neyakanyanya tembiricha tembiricha mudziyo uye tembiricha yekudzora system,
B, yakagadzirirwa neyakanyanya kupisa tembiricha inodhonza tsvimbo (sampula fixture)
C, yakagadzirirwa neCreep extnsometer (deformation kudhirowa mudziyo)
D, yakagadzirirwa nechiridzwa chekuparadza (deformation yekuyera kuyera).
Iyo Creep Properties yezvinhu inogona kuyerwa pasi pekugara uchiisa tembiricha uye anogara achiita mutoro.
