Elastic Modulus, Temperature Coefficient, thiab siab -Tsuas Kev Pabcuam Kev Ua Haujlwm ntawm Elastic Clips
Qhov kub coefficient ntawm elastic modulus ntawm elastic clip yog -0.02% / degree, nws yuav ua li cas rau lub zog clamping hloov?
Rau txhua txhua 10℃nce nyob rau hauv qhov kub thiab txias, lub elastic modulus ntawm elastic clip txo los ntawm 0.2%, thiab lub clamping quab yuam txo synchronously los ntawm 0.2%. Piv txwv li, thaum qhov kub ib txwm yog 25 degree, lub zog clamping ntawm elastic clip yog 10kN, thiab ntawm 55℃siab kub, lub clamping quab yuam poob mus rau 9.7kN, 3% txo. Yog tias qhov ntsuas kub tseem nce mus txog 70 degree, lub clamping quab yuam tuaj yeem ncav cuag 9%, uas tsis tuaj yeem kaw qhov kev tsheb ciav hlau zoo. Qhov no yog vim qhov nce hauv qhov kub thiab txias yuav ua rau cov saw hlau molecular txav ntawm cov khoom siv elastic clip, txhim khu lub peev xwm elastic deformation, ua rau txo qis hauv preload. Qhov kub thiab txias nyob rau hauv tib yam - cov kab ceev yuav kav ib lub sij hawm luv luv, thiab qhov kev lwj yog siv tau. Txawm li cas los xij, siab -ceev thiab hnyav- cov kab tsheb yuav tsum tau txo qhov kub coefficient los ntawm cov khoom siv kom zoo.
Vim li cas 60Si2CrA elastic clips xaiv rau siab - qhov kub thiab txias tsis yog 60Si2MnA elastic clips?
Qhov kub coefficient ntawm 60Si2MnA elastic clips yog -0.025% / degree, thiab elastic modulus poob sai dua nyob rau hauv qhov kub thiab txias, nrog rau clamping quab yuam decay tus nqi ntawm 0.25% /℃. 60Si2CrA elastic clips ntxiv chromium ntsiab, txo qhov kub coefficient rau {0.{015% a degree} elastic modulus poob tus nqi. Ntawm 50℃siab kub, lub clamping quab yuam ntawm 60Si2CrA elastic clips tsuas yog 3%, thaum ntawm 60Si2MnA elastic clips ncav cuag 5%. Tsis tas li ntawd, qhov kub-txias lub zog tuav tus nqi ntawm 60Si2CrA elastic clips yog ntau dua los yog sib npaug li 85%, ntau dua 70% ntawm 60Si2MnA, uas tuaj yeem tiv taus cov yas deformation nyob rau hauv qhov kub thiab txias. Nws yog qhov zoo dua elastic clip rau qhov chaw kub.
Dab tsi cuam tshuam yuav qis dua elastic modulus ntawm elastic clip muaj rau kev khiav smoothness?
Tsis tshua muaj elastic modulus ntawm elastic clip yuav ua rau ntau deformation nyob rau hauv tib lub load, rail kev daws teeb meem tshaj tus nqi tsim, thiab cov khiav smoothness txo. Piv txwv li, thaum lub elastic modulus poob los ntawm 200GPa rau 160GPa, txoj kev tsheb ciav hlau kev sib haum xeeb nce los ntawm 20%, thiab txoj kev tsheb ciav hlau nto yuav uneven. Thaum lub tsheb ciav hlau hla, nws yuav ua rau muaj kev cuam tshuam ntxiv, ua rau lub log hnyav dua - tsheb ciav hlau, thiab tib lub sijhawm, hauv qab - tsheb ciav hlau ncoo tau raug kev nyuaj siab tsis sib xws, ua rau lub zos compression deformation. Ntev - lub sij hawm tsis tshua muaj elastic modulus yuav ua rau tsub zuj zuj ntawm qhov sib txawv ntawm qhov ntev ntawm cov duab geometric, ua rau cov kab ntau zaus thiab cuam tshuam rau kev tsav tsheb. Yog li ntawd, lub elastic modulus ntawm elastic clip yuav tsum tau tswj nyob rau hauv qhov ntau ntawm 190-210GPa los xyuas kom meej qhov smoothness.
Yuav ua li cas los txheeb xyuas qhov elastic modulus thiab qhov kub thiab txias coefficient ntawm elastic clip ntawm qhov chaw los txiav txim qhov siab -kub adaptability?
On site, a high-temperature elastic modulus tester can be used to detect the elastic modulus of the elastic clip at three temperatures: 25℃, 50℃, and 70℃, and calculate the temperature coefficient. Elastic clips with a temperature coefficient ≤-0.015%/℃ are suitable for high-temperature areas, while those with a temperature coefficient >-0.02% /℃tsis yog. Nyob rau tib lub sijhawm, kev ntsuas kub ntawm lub zog clamping tuaj yeem ua tiav. Muab qhov elastic clip tso rau hauv ib puag ncig 50℃thiab kuaj xyuas qhov clamping quab yuam kom tawg; kev lwj tsawg dua lossis sib npaug li 5% yog tsim nyog. Tsis tas li ntawd, saib qhov deformation ntawm elastic clip nyob rau hauv qhov kub thiab txias; tsis muaj yas deformation yog tsim nyog, thiab deformation qhia tsis txaus elastic modulus, yuav tsum tau hloov.
Dab tsi cuam tshuam qhov kev hloov pauv ntawm cov qauv elastic ntawm lub elastic clip muaj nyob rau tag nrho cov tawv nqaij ntawm lub fastening system?
Kev hloov pauv ntawm ± 10GPa nyob rau hauv lub elastic modulus ntawm elastic clip yuav ua rau ib tug 15% -20% fluctuation nyob rau hauv tag nrho cov nruj ntawm lub fastening system. Siab elastic modulus ntau dhau yuav ua rau me me deformation ntawm elastic clip thiab ntau dhau clamping quab yuam, ua rau cov pw tsaug zog compressive kev nyuaj siab thiab ua rau kom pw tsaug zog puas tsuaj; Tsis tshua muaj elastic modulus yuav ua rau loj deformation ntawm elastic clip thiab tsis txaus clamping quab yuam, ua rau txoj kev tsheb ciav hlau khiav thiab txo txoj kev nruj. Lub zuag qhia tag nrho nruj ntawm lub fastening system yuav tsum phim cov kab load. Kev hloov pauv ntawm elastic modulus ntawm elastic clip yuav tsum tau tswj tsis pub dhau ± 5Gpa kom ntseeg tau tias qhov ruaj khov ntawm qhov system nruj, zam kev hloov pauv ntawm txoj kev khiav nrawm, thiab cuam tshuam rau kev khiav haujlwm ntawm lub tsheb ciav hlau.
