Haum rau tsheb hluav taws xob siab sensor 1846481C92

Mechanical method

Kev kho tshuab kev ruaj ntseg feem ntau yog ua tiav thaum cov khoom tsim tau tsim tom qab cov nyiaj them poob haujlwm thiab kev hloov kho ntawm cov khoom siv hluav taws xob thiab cov khoom siv tiv thaiv. Cov txheej txheem tseem ceeb yog pulse qaug zog txoj kev, overload static siab txoj kev thiab vibration aging txoj kev.

(1) Pulsating qaug zog txoj kev

Lub xovtooj ntawm tes tau nruab rau ntawm lub tshuab ntsuas kev qaug zog tsawg, thiab qhov txwv sab saud yog ntsuas qhov load lossis 120% rated load, thiab lub voj voog yog 5,000-10,000 zaug ntawm zaus ntawm 3-5 zaug ib ob. Nws tuaj yeem tso tawm qhov kev ntxhov siab ntawm cov khoom seem ntawm elastic, tiv thaiv kab mob gage thiab strain adhesive txheej, thiab cov nyhuv ntawm kev txhim kho xoom taw tes thiab rhiab heev stability yog qhov pom tseeb heev.

(2) Overload static siab txoj kev

Raws li txoj cai, nws yog qhov tsim nyog rau txhua yam kev ntsuas qhov ntsuas, tab sis hauv kev tsim cov tswv yim, aluminium alloy me-ntau zog sensor yog dav siv.

Cov txheej txheem yog raws li nram no: nyob rau hauv ib tug tshwj xeeb tus qauv hnyav loading ntaus ntawv los yog yooj yim mechanical ntsia hlau loading khoom, thov 125% rated load rau lub load cell rau 4-8 teev, los yog siv 110% rated load rau 24 teev. Ob qho txheej txheem tuaj yeem ua tiav lub hom phiaj ntawm kev tso cov kev ntxhov siab seem thiab txhim kho xoom taw tes thiab rhiab heev stability. Vim tias cov cuab yeej siv yooj yim, tus nqi qis thiab cov txiaj ntsig zoo, cov txheej txheem overload zoo li qub yog dav siv los ntawm aluminium alloy load cell manufacturers.

(3) vibration aging method

Lub load cell yog ntsia rau ntawm lub vibration platform nrog rated sinusoidal thrust ua tau raws li qhov yuav tsum tau ntawm kev co laus, thiab qhov zaus yog kwv yees raws li qhov ntsuas ntawm qhov hnyav ntawm tes los txiav txim siab qhov kev vibration load, ua hauj lwm zaus thiab vibration sij hawm. Resonance aging yog zoo dua li kev vibration aging nyob rau hauv tso residual kev nyuaj siab, tab sis lub ntuj zaus ntawm lub load cell yuav tsum tau ntsuas. Vibration aging thiab resonance aging yog tus cwj pwm los ntawm kev siv hluav taws xob tsawg, lub sij hawm luv luv, cov txiaj ntsig zoo, tsis muaj kev puas tsuaj rau saum npoo ntawm cov khoom elastic thiab kev ua haujlwm yooj yim. Lub mechanism ntawm kev co aging yog tseem inconclusive. Cov kev xav thiab cov kev xav tau muab tso rau los ntawm cov kws tshaj lij txawv teb chaws muaj xws li: yas deformation theory, qaug zog txoj kev xav, lattice dislocation slip txoj kev xav, lub zog saib thiab cov khoom siv tshuab kev xav.
