Indlela yokubala Umthamo womthwalo weNtsontelo yeNtsimbi yeNtsimbi engatyiwayo

Xa ukhetha iintambo zensimbi engenasici kwizicelo zemizi-mveliso, enye yezona zinto zibalulekileyo ekufuneka ziqwalaselwe yizoumthamo womthwalo. Ingaba intambo yocingo isetyenziswa kuyoukuphakamisa, ukuphakamisa, ukutsala, okanyeukweyisaizicelo, kufuneka ikwazi ukuphatha ngokukhuselekileyo imithwalo elindelekileyo. Ukuqonda indlela yokubala umthamo womthwalo wentambo yensimbi engenasici kubalulekile ekuqinisekiseni ukhuseleko, ukuthembeka, kunye nokusebenza kakuhle kwemisebenzi yakho. Kwesi sikhokelo, siza kuchaza ukubala umthamo womthwalo weentambo zentsimbi engenasici, sithathela ingqalelo izinto ezibalulekileyo ezifana nokwakhiwa kweentambo, ibakala lemathiriyeli, kunye nemiba yokhuseleko.

Yintoni Umthamo womthwalo weNtsontelo yocingo lwentsimbi?

Iumthamo womthwaloIntambo yocingo ibhekisa kubunzima obukhulu okanye amandla enokuthi intambo ibambe ngokukhuselekileyo ngaphandle kokusilela. Lo mthamo uxhomekeke kwizinto ezahlukeneyo ezifana nentamboububanzi, ukwakhiwa, ibakala lemathiriyeli, kwayeiimeko zokusebenza. Ukuqikelelwa ngendlela engafanelekanga okanye ukugqithiswa komthamo womthwalo kunokukhokelela kukusilela okuyintlekele, oko kukwenza kubaluleke ukubala umthamo ochanekileyo womthwalo ngaphambi kokusetyenziswa.

Imiba ePhambili echaphazela iSakhono soMthwalo

  1. Ububanzi beNtambo
    Ububanzi bentambo yocingo buchaphazela ngokuthe ngqo umthamo walo womthwalo. Iintambo ezinkulu zedayamitha ziyakwazi ukuthwala imithwalo enzima ngenxa yokwanda kwendawo, ngelixa iintambo ezincinci zedayamitha zifanelekile kwimithwalo elula. Umthamo womthwalo uyanda njengoko ububanzi bentambo bukhula, kodwa kunjalo ubunzima kunye nokuguquguquka kwentambo.

  2. Ukwakhiwa kweeNtambo
    Iintambo zocingo lwentsimbi estainless zakhiwe ngokweendlela ezahlukeneyo, ezidla ngokubizwa ngokuba yintambo yentambo.ukwakhiwa. Umzekelo, a6×19 ukwakhiwaiqulethe imicu emi-6, nganye ineengcingo ezili-19. Uhlobo lolwakhiwo luchaphazela ukuguquguquka kwentambo, ukomelela, kunye nokumelana nokunxiba. Ngokuqhelekileyo, iintambo ezinemisonto eninzi zibhetyebhetye ngakumbi kodwa zinokuba nomthamo ophantsi womthwalo xa kuthelekiswa neentambo ezinemisonto embalwa.

  3. IBanga leMathiriyeli
    Ibakala lensimbi engenasici esetyenzisiweyo kwintambo yocingo lichaphazela amandla ayo obunzima kwaye, ngenxa yoko, umthamo walo womthwalo. Amabanga aqhelekileyo asetyenziselwa iintambo zentsimbi engenasici aquka:

    • I-AISI 304: Iyaziwa ngokuxhathisa umhlwa kodwa amandla asezantsi okuqina xa kuthelekiswa namanye amabanga.

    • I-AISI 316: Inikezela ngoxhathiso oluphezulu lwe-corrosion, ngakumbi kwiindawo ezihlala elwandle, kwaye isetyenziswa kakhulu kwizicelo ezifuna amandla aphezulu.

    • I-AISI 316L: I-low-carbon version ye-AISI 316, ebonelela nge-weldability engcono kunye nokumelana nokugqwala kwiindawo ezinzima.

    Okukhona liphezulu ibakala lentsimbi engatyiwayo, kokukhona ukuba mkhulu ukomelela kwentambo kunye nomthamo womthwalo.

  4. Inani leeNcingo kunye nemisonto
    Inani leengcingo kumsonto ngamnye kunye nenani leentambo kwintambo ichaphazela amandla ayo onke. Intambo eneengcingo ezininzi kunye nemisonto inika amandla angcono kunye nokuguquguquka, kodwa inokunciphisa ukuxhathisa kwentambo kwi-abrasions ngenxa yendawo engaphezulu evezwe ukuba iguge.

  5. Umba woKhuseleko
    Iukhuseleko factorsisiphindaphindi esisetyenziswayo kumthamo obaliweyo womthwalo wokuphendula ngoxinzelelo olungalindelekanga, iimeko zokusingqongileyo, kunye nokuqwalaselwa kokhuseleko. Umba wokhuseleko ukhethwa ngokuqhelekileyo ngokusekelwe kubume besicelo. Umzekelo:

    • Ukwakhiwa kunye nokwembiwa kwemigodi: Umba wokhuseleko we-5:1 (okt, intambo kufuneka ikwazi ukuphatha ngokuphindwe kahlanu ubukhulu bomthwalo olindelekileyo) isetyenziswa ngokuqhelekileyo.

    • Ukuphakamisa kunye nokunyusa: Ukhuseleko lwe-6: 1 okanye 7:1 lunokufaneleka, ngakumbi kwimisebenzi ebalulekileyo yokuphakamisa apho ukhuseleko luhamba phambili.

Indlela yokubala Umthamo womthwalo weNtsontelo yeNtsimbi yeNtsimbi engatyiwayo

Ngoku siyaziqonda izinto ezichaphazela umthamo womthwalo, makhe sidlule kwinkqubo yokubala. Ifomula ngokubanzi yokubala umthamo womthwalo wentambo yentsimbi engenasici yile:

Amandla oMlayisho (kN)=Amandla oKuqhawula (kN)/IFactor yoKhuseleko\teksti{Umthamo woMlayisho (kN)} = \umbhalo{Amandla oKwaphula (kN)} / \umbhalo{Umba woKhuseleko}

Amandla oMlayisho (kN)=Amandla oKuqhawula (kN)/Isibakala soKhuseleko

Apho:

  • Ukuqhawula Amandla: La ngawona mandla aphezulu okanye umthwalo onokuthi intambo imelane phambi kokuba iqhawuke. Ngokuqhelekileyo ibonelelwa ngumenzi okanye ingabalwa ngokusebenzisa amandla e-tensile yezinto zentambo kunye nommandla wayo onqamlezayo.

  • Umba woKhuseleko: Njengoko kuxoxiwe ngaphambili, esi siphindaphinda esiqinisekisa ukuba intambo inokusingatha imithwalo engalindelekanga.

Amandla okuqhawuka kwentambo yocingo angabalwa ngolu hlobo lulandelayo:

Amandla Okwaphuka (kN)=Ukuqina kweNtsimbi (kN/mm²)×INdawo eNqamkileyo yeNtsontelo (mm²)\text{Amandla okuHamba (kN)} = \umbhalo{Ukuqina kweNtsimbi (kN/mm²)} \ amaxesha \isicatshulwa{Indawo enqamlezileyo (mm²)}

Ukomelela Kokuqhawuka (kN)=Ukomelela kweNtsimbi (kN/mm²)×Ummandla onqamlezileyo weNtsontelo (mm²)

Umzekelo wokubala weNyathelo ngeNyathelo

Masingene kwisibalo esisisiseko sokuqonda umthamo womthwalo wentambo yentsimbi engenasici:

  1. Gqiba Amandla Okuqina Kwezinto
    Umzekelo, i-AISI 316 insimbi engenasici inamandla aqhelekileyo okujikeleza2,500 MPa(MegaPascal) okanye2.5 kN/mm².

  2. Bala uMmandla oMnqamlezo weNtsontelo
    Ukuba sinentambo ene-aububanzi be-10 mm, indawo ye-cross-sectional (A) yentambo ingabalwa ngokusebenzisa ifomyula yendawo yesangqa:

    A=π×(d2)2A = \pi \amaxesha \ekhohlo(\frac{d}{2}\ekunene)^2

    A=π×(2d​)2

    Apho
    dd

    d bububanzi bentambo. Ngentambo ye-10 mm yobukhulu:

    A=π×(102)2=π×25=78.5 mm²A = \pi \amaxesha \ekhohlo(\frac{10}{2}\ekunene)^2 = \pi \amaxesha 25 = 78.5 \, \umbhalo{mm²}

    A=π×(210​)2=π×25=78.5mm²

  3. Bala Amandla okuqhawula
    Ukusebenzisa amandla okuqina (2.5 kN/mm²) kunye nommandla onqamlezileyo (78.5 mm²):

    Amandla Okwaphula=2.5×78.5=196.25 kN\umbhalo{Amandla Okwaphula} = 2.5 \amaxesha 78.5 = 196.25 \, \umbhalo{kN}

    Ukwaphuka Amandla=2.5×78.5=196.25kN

  4. Sebenzisa iFactor yoKhuseleko
    Kuthathwa ukhuseleko lwe-5:1 kwisicelo sokuphakamisa jikelele:

    Umthamo womthwalo=196.255=39.25 kN\text{Umthamo womthwalo} = \frac{196.25}{5} = 39.25 \, \umbhalo{kN}

    Umthamo womthwalo=5196.25=39.25kN

Ngaloo ndlela, umthamo womthwalo we-10 mm ububanzi bentambo yentsimbi yensimbi engenasici, eyenziwe kwi-AISI 316 yensimbi engenasici, kunye nokhuseleko lwe-5: 1, iphantse.39.25 kN.

Ukubaluleka koBalo lokuLawulwa okuLungileyo

Ubalo oluchanekileyo lomthamo womthwalo luqinisekisa ukuba intambo inokusingatha umthwalo olindelekileyo ophezulu ngaphandle komngcipheko wokungaphumeleli. Ukulayisha ngaphezulu intambo yocingo kunokukhokelela kwiziphumo ezibi, kubandakanya ukuqhawuka kwentambo, ukusilela kwesixhobo, kwaye, ngokubaluleke kakhulu, iingozi. Kubalulekile ukulandela izikhokelo zokhuseleko kwaye unike ingxelo ngezinto eziguquguqukayo ezifana neemeko zokusingqongileyo, ukuguga, kunye nobudala bentambo.

Ukongeza, kubalulekile ukuhlola rhoqo kunye nokugcina iintambo zentsimbi engenasici ukuqinisekisa ukuba ziyaqhuba ukuhlangabezana nesakhono sazo sokuthwala umthwalo.
