Classic Cov Qauv Hlau Qauv Q & A
1. Thaum koj saib lub sijhawm ntawm lub sijhawm khoov, koj tuaj yeem pom lub sijhawm dabtsi, tab sis koj tsis paub dab tsi yog qhov kev sib raug zoo ntawm lub sijhawm khoov thiab hla ntu.
Teb: Tus Bending tus tswv cuab raug rau tus dab nqa muaj peev xwm ua tau zoo MX / (GAMMA Y *
2. Cov cai ntawm H-Beach yog dab tsi?
Teb: Yuav teb li cas, Hehe. Kev txiav txim siab tseem ceeb yog khoov rau lub sijhawm thiab / lossis cov kis tau ntawm shear zog. Tsis tas li ntawd, nyob rau hauv cov chaw tsim khoom dynamic, tsim qauv veb pob qij txha yuav tsum yog tshwj xeeb tshaj yog txuas:
3. "Tiaj tiaj sab saum toj nruj", tsis tas yuav rov qab los tom qab tiding?
A: Polishing sab saum toj yog hom kev sib kis tau, uas tau siv los ua kom muaj txoj haujlwm ntawm kev txav chaw.Ib hom kev sib kis kom tsis txhob muaj zog nkees dhau ntawm Welds.Nws yog qhov yuav tsum tau hais tias kev ua polishing ntawm qhov saum yuav tsum tsis txhob siv cov.Saib cov kev cai kos duab tshwj xeeb.Lub rooj sib ze yuav tsum tau hais tias qhov tiav tsis tsawg tshaj 12.5, thiab thaj chaw tiv tauj yuav tsum tau txheeb xyuas nrog ntsaws ntsuas.Lub dav hlau ncaj sab saum toj nruj lub hom phiaj yog kom nce thaj tsam ntawm thaj chaw sib txuas, xws li flange ntawm kev sib txuas (xws li Flange flange, nws muaj peev xwm siv web bolted).
Feem ntau cov kev cai ntawm lub dav hlau ncaj sab saum toj nruj tsis tas yuav ua kom nruj me ntsis yog tsis zoo, welded ntu txawm tias lawv tsis qhib zawj yuav tsis nug tas li.Sab saum toj nruj thiab vuam yog qhov sib cav sib ceg, yog ib qho yuav tsis txaus ntseeg, thiab tsis muaj lwm txoj kev ywj pheej ntawm kev ywj pheej, nws tsis yooj yim sua kom tag nrho cov kev ywj pheej, nws tsis tuaj yeem siv rau kev siv vuam Weld.
4. Thaum tus qauv steel yog tsim, qhov deflection tshaj qhov txwv tus nqi, tom qab sib tham yam yuav tshwm sim?
Teb: cuam tshuam rau kev siv ib txwm muaj lossis tsos ntawm deformation;Kev puas hauv zos (suav nrog cov kab nrib pleb hauv zos) uas cuam tshuam rau kev siv lossis kav ntev.Cuam tshuam rau kev co ntawm kev siv ib txwm;Lwm cov xwm txheej tshwj xeeb uas cuam tshuam rau kev siv zoo li qub.
5. Dab tsi yog qhov ua haujlwm ntawm extruded phaj?
Teb: extruded polystyrene (xps) rwb thaiv tsev board, polystyrene cob qhia, los ntawm cov txheej txheem tshwj xeeb extrusion feam tsim cov ntawv tawv tawv.Nrog rau tus qauv tshwj xeeb thiab zoo tshaj plaws honeycomb, nws muaj cov ntaub ntawv zoo ib puag ncig, xws li thermal ua hauj lwm, qis zog, lub neej ntev, ntev.Lub extruded polystyrene rwb thaiv tsev board yog dav siv nyob rau hauv phab ntsa phab ntsa, chaw nres tsheb pob zeb, lub tsev ua vaj tse lub ru tsev ru tsev ru tsev, thiab lwm yam.Lub phaj extruded muaj qhov zoo tshaj plaws thiab ua rau tus yam ntxwv zoo kawg nkaus: nws yog ruaj khov thiab tsis yooj yim rau hnub nyoog.Muaj 30 -- 50 xyoo, tsis tshua muaj cua sov cov pa vapor ib puag ncig, tseem tuaj yeem tswj thermal bermal conductivity.Lub thawv extruded muaj cov thermal rwb thaiv tsev ua haujlwm: lub extruded phaj muaj lub ntsej muag kaw thiab yog nws muaj cov cua sov kev ua haujlwm zoo.Txawm hais tias foaming polyurethane yog cov qauv obturetian, qhov kaw yog tsawg dua li cov extruded phaj, tsuas yog hais txog 80%.Cov phaj extruded yog zoo dua rau lwm cov ntaub ntawv insulating, xws li rwb thaiv tsev kom sov, lub zog kub, yog li nws tsis muaj peev xwm siv rau hauv thermal rwb thaiv tsev.Extruded Board tau npaj txhij txog compressive lub zog: compressive zog ntawm cov qauv sib xyaw ua ke raws li lub zog sib xyaw ua ke raws li lub zog sib xyaw, thiab lwm yam qis dua li lub zog compressive ntawm supruded board.Lub phaj extruded muaj cov khoom siv nyab xeeb: nws yog siv rau txoj kev saum npoo av thiab txoj kev ua si, siv tau dej tsis zoo.Tshwj xeeb tshaj yog nyob rau sab qaum teb, nws tuaj yeem txo te ncu thiab khov cuam tshuam cov av khov khov thiab ua kom khov kho cov roj av hauv av los ntawm cov av noo thiab lwm yam.
6. Dab tsi yog qhov ntev thiab nthuav dav?Lub vojvoog ntawm tig: lub hauv paus xwm fab ntawm (lub sijhawm ntawm inertia / cheeb tsam) ntev) ntev yog sib npaug los xam ntev / vojvoog ntawm kev sib hloov
Teb: Qhov ntev ntawm tus qauv yog ntau dua li lambda=l / i, thiab kuv yog qhov ntev ntawm vojvoog ntawm kev sib hloov.Lub tswvyim tuaj yeem pom tau yooj yim ntawm cov kev ua ke cov formulation: Qhov sib piv ntawm qhov ntev ntev yog qhov ntsuas ntawm qhov kev suav nrog rau nws txoj kev tig vojvoog.Los ntawm cov mis no, nws tuaj yeem pom tau hais tias lub tswvyim ntawm kev sib piv zoo ntev yuav siv sijhawm ntawm qhov kawg ntawm cov tivthaiv, qhov ntev ntawm cov khoom siv nws tus kheej thiab cov yam ntxwv ntawm cov khoom sib xyaw.Cov nyhuv ntawm cov piv txwv me me yog pom tseeb rau qhov kev ua lej ruaj khov ntawm qhov loj ntawm cov tswv cuab, vim tias qhov loj dua ntawm tus tswvcuab, qhov ntau dua nws yog qhov tsis ruaj khov.Saib ntawm kev laij cov kev suav ntawm cov kev txiav siab ntawm Axial siab thiab siab khoov cov khoom siv, txhua tus uas muaj qhov tsis sib xws nrog qhov ntev ntawm cov piv.Rau cov ntsuas tensile, nws tseem muab cov kev xav tau ntev ntev, uas yog kom lav tau lub zog ntawm cov khoom thauj thiab cov mob installation.Qhov siab dua qhov yuav tsum tau muaj zog, qis dua qhov kev ruaj khov.
Lub buckling ntawm lub compression fless ntawm lub curved i-nqaj yog underdirection ntawm lub nqaj ntawm lub qhov muaj zog?
Teb: Thaum lub load tsis loj, nqaj nyob rau hauv nws qhov loj tshaj plaws hauv-dav hlau dement thiab torsion deforming nyob rau tib lub sijhawm, kawg sai no poob mus txuas ntxiv mus muaj peev xwm.Lub sijhawm no, tag nrho cov kev ruaj ntseg ntawm cov nqaj yuav tsum tau khoov thiab sib ntswg.
