Dab tsi bolts yog qhov zoo tshaj plaws rau kev kub siab?

Bolts siv rau hauv cov ntawv thov kub yuav tsum muaj peev xwm tiv taus qhov kub thiab txias yam tsis tau poob lawv cov khoom siv kho tshuab lossis kev ncaj ncees. Ntau hom bolts thiab fasteners yog tsim los rau qhov kub thiab txias, xws li:

1. Alloy Steel Bolts: Bolts ua los ntawm cov hlau alloy, xws li ASTM A193 Qib B7, yog tsim rau kev siv kub. Cov bolts no tau txais kev kho cua sov kom muab lub zog zoo thiab nkag mus rau qhov kub thiab txias.

2. Stainless hlau bolts: Qee qib ntawm cov hlau tsis muaj steel, xws li 310 stainless hlau, paub txog lawv qhov kub thiab txias. Cov bolts no muaj kev tiv thaiv oxidation zoo thiab khaws lawv lub zog ntawm qhov kub thiab txias.

3. Inconel bolts: Inconel yog ib tsev neeg ntawm nickel-chromium-raws li high-temperature alloys paub txog nws zoo heev kub-kub lub zog thiab oxidation kuj. Inconel bolts yog tsim rau siv nyob rau hauv huab cua kub ib puag ncig xws li roj turbine thiab aerospace daim ntaub ntawv.

4. Titanium bolts: Titanium thiab titanium alloy bolts yog lub teeb hauv qhov hnyav thiab muaj lub zog zoo ntawm qhov kub thiab txias. Lawv feem ntau siv nyob rau hauv aerospace thiab tshuaj ua daim ntaub ntawv uas yuav tsum tau kub kub kuj.

5. Refractory hlau bolts: Bolts ua los ntawm cov hlau refractory xws li molybdenum, tantalum, thiab niobium yog haum rau qhov kub thiab txias, xws li lub tshuab nqus tsev vacuum thiab semiconductor manufacturing.

Thaum xaiv bolts rau cov ntawv thov kub, nws yog ib qho tseem ceeb uas yuav tau xav txog qhov kub thiab txias, ib puag ncig thiab kev xav tau ntawm kev siv tshuab. Tsis tas li ntawd, kev txhim kho kom zoo thiab kev tsim cov fastener xav tau yog qhov tseem ceeb rau kev ua haujlwm ntev thiab kev ntseeg siab ntawm bolts hauv qhov chaw kub kub.

Qhov kub puas cuam tshuam lub zog tensile?

Yog, qhov kub thiab txias tuaj yeem cuam tshuam rau lub zog tensile ntawm cov khoom. Feem ntau, lub zog tensile ntawm cov ntaub ntawv txo qis thaum kub nce. Qhov tshwm sim no tshwj xeeb yog tshwm sim hauv cov hlau thiab hlau, tab sis nws kuj siv rau lwm cov ntaub ntawv.

Cov nyhuv ntawm qhov kub ntawm lub zog tensile yog cuam tshuam los ntawm ntau yam, nrog rau cov khoom muaj pes tsawg leeg, microstructure, thiab muaj cov ntsiab lus alloying. Nov yog qee cov ntsiab lus tseem ceeb los xav txog:

1. Cov Khoom Siv Hluav Taws Xob: Ntau cov ntaub ntawv ductile, xws li carbon steel, poob lub zog tensile thaum kub nce. Qhov no yog vim muaj kev txav mus los ntawm kev txav mus los hauv cov khoom siv lead ua lattice ntawm qhov kub siab dua, uas tuaj yeem ua rau muaj kev cuam tshuam ntau dua rau deformation thiab txo lub zog.

2. Cov ntaub ntawv brittle: Qee cov ntaub ntawv, tshwj xeeb tshaj yog cov alloys thiab ceramics, tej zaum yuav ua rau muaj kev coj cwj pwm zoo nrog qhov kub thiab txias. Piv txwv li, qee cov ntaub ntawv nkig tuaj yeem ua rau muaj zog tensile ntawm qhov kub siab vim qhov kev hloov ntawm cov khoom siv tus cwj pwm tawg.

3. Kub kub alloys: Qee qhov kub kub alloys, xws li cov siv hauv aerospace thiab fais fab kev siv, yog tsim tshwj xeeb los tswj lawv lub zog tensile ntawm qhov kub thiab txias. Cov alloys no yog tsim los tiv thaiv softening thiab tswj lawv cov khoom siv kho tshuab hauv qhov kub thiab txias.

4. Creep: Ntxiv rau qhov muaj kev cuam tshuam ncaj qha rau lub zog tensile, qhov kub thiab txias kuj tuaj yeem ua rau creep, uas yog maj mam deformation ntawm cov ntaub ntawv nyob rau hauv tas li load. Creep tuaj yeem txo cov khoom siv lub zog tensile zoo nyob rau lub sijhawm ntawm qhov kub siab.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tus cwj pwm tshwj xeeb ntawm cov khoom siv lub zog tensile raws li kev ua haujlwm ntawm qhov kub thiab txias yog nyob ntawm nws qhov muaj pes tsawg leeg, kev ua haujlwm, thiab kev thov. Thaum tsim cov khoom siv rau hauv qhov chaw kub kub, nws yog ib qho tseem ceeb kom xav txog qhov muaj peev xwm ntawm qhov kub thiab txias ntawm lub zog tensile ntawm cov khoom siv.

Hauv cov ntsiab lus, thaum lub zog tensile ntawm cov khoom tuaj yeem cuam tshuam los ntawm qhov kub thiab txias, qhov tseeb ntawm cov nyhuv no nyob ntawm cov khoom siv thiab nws cov khoom tshwj xeeb. Kev nkag siab txog yuav ua li cas cov ntaub ntawv coj tus cwj pwm nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias yog qhov tseem ceeb rau kev ua haujlwm txhim khu kev qha ntawm cov khoom siv hluav taws xob hauv cov ntawv thov kub.
