(1) Kev npaj ua ntej kev xeem
Kev tshuaj xyuas cov cuab yeej: Paub meej tias tsis muaj kab nrib pleb lossis xoob hauv lub tshuab ua haujlwm, clamps, thiab sensors, tias cov cables tau txuas ruaj khov, thiab cov khoom sib kis tau ua tiav lubricated.
Kev lees paub ib puag ncig: Khaws thaj chaw kuaj kom huv thiab huv si, tswj qhov kub ntawm 20 ± 5 degree, av noo tsawg dua lossis sib npaug li 75% RH, thiab tsis txhob cuam tshuam electromagnetic.
Fixture xaiv: Xaiv cov khoom siv tshwj xeeb raws li cov khoom siv (hlau / yas / roj hmab) thiab hom kev sim (nruj / compression / dabtsi yog khoov). Cov ntaub ntawv nkig yuav tsum tau siv cov ntaub mos mos los tiv thaiv ua ntej - tawg, thiab siab - cov qauv ntsuas kub yuav tsum tau txias rau chav tsev kub ua ntej clamping.
(2) Kev xeem ua tiav
Qauv clamping: Txhim kho cov qauv hauv nruab nrab ntawm cov khoom siv sab saud thiab qis kom ntseeg tau tias qhov yuam kev axial coaxiality yog<0.5mm. The clamping force of metal samples needs to reach 70%-80% of the yield strength, and the clamping force of plastic samples should be controlled within 50%.
Kev teeb tsa Parameter: Nkag mus rau qhov ntsuas ceev (0.001-500mm/min), quab yuam ntau (0.2%-100%FS) thiab cov ntaub ntawv kaw zaus los ntawm kev tswj vaj huam sib luag lossis software interface. Tus qauv nrawm rau kev ntsuas tensile feem ntau yog 10-50mm / min, thiab kev xaiv servo system rau kev ntsuas siab tuaj yeem ua tiav 0.01mm / min qib kev hloov kho.
Kev saib xyuas cov txheej txheem: Saib xyuas qhov quab yuam tus nqi nkhaus thiab cov cuab yeej ua haujlwm raws li txoj cai thoob plaws tag nrho cov txheej txheem tom qab pib. Nres tam sim ntawd thaum muaj kev co txawv txav lossis cov ntaub ntawv hloov pauv tshwm sim. Kev poob qis ntawm tus nqi quab yuam thaum lub sijhawm tawg ntawm cov qauv hlau yuav tsum yog<5%/ms, and that of plastic specimens is allowed to reach 10%/ms.
(3) Tom qab- kev xeem ua tiav
Kev txuag cov ntaub ntawv: Tsis siv neeg tsim cov ntawv xeem suav nrog lub zog tensile, elongation ntawm kev so thiab lwm yam tsis muaj, txhawb nqa cov duab kos duab thiab ntau - nkhaus sib piv.
Kev tu cov cuab yeej: Ntxuav cov khoom seem seem, xyuas qhov tseeb ntawm qhov ntsuas, thiab ntxiv lithium- roj raws li cov ntsia hlau ntsia hlau txhua lub hli. Thaum tawm ntawm kev pabcuam rau lub sijhawm ntev, lub zog yuav tsum raug txiav tawm thiab npog nrog plua plav npog.
