Ịtụ n'ụzọ ezighi ezi ma ọ bụ karịa ikike ibu nwere ike ibute ọdịda dị egwu, na-eme ka ọ dị mkpa ịgbakọ ikike ibu ziri ezi tupu ejiri ya.

Isi ihe na-emetụta ike ibu

1. Ogologo eriri
   Dayameta nke eriri waya na-emetụta ikike ibu ya ozugbo. Ụdọ dayameta buru ibu nwere ike ijikwa ibu dị arọ n'ihi ụbara elu elu, ebe obere eriri eriri kwesịrị ekwesị maka ibu dị mfe. Ike ibu na-abawanye ka dayameta nke eriri na-abawanye, ma otú ahụ ka ịdị arọ na mgbanwe nke eriri ahụ na-abawanye.

2. Mwube eriri
   A na-arụ eriri igwe anaghị agba nchara na nhazi dị iche iche, nke a na-akpọkarị eririihe owuwu. Dịka ọmụmaatụ, a6 × 19 ihe owuwunwere eriri isii, nke ọ bụla nwere wires iri na itoolu. Ụdị ihe owuwu ahụ na-emetụta ngbanwe nke eriri, ike, na iguzogide iyi. Dị ka ọ na-adịkarị, ụdọ ndị nwere ọtụtụ eriri na-agbanwe agbanwe mana ọ nwere ike ịnwe ikike ibu dị ala ma e jiri ya tụnyere ụdọ nwere obere eriri.

3. Ọkwa ihe
   Ọkwa nke igwe anaghị agba nchara eji eriri waya na-emetụta ike ike ya na, n'ihi ya, ikike ibu ya. Ọkwa a na-ejikarị eme eriri igwe anaghị agba nchara gụnyere:

   • AISI 304: Amara maka nguzogide corrosion ya mana ike ike dị ala ma e jiri ya tụnyere akara ule ndị ọzọ.

   • AISI 316: Na-enye nguzogide corrosion ka elu, karịsịa na gburugburu mmiri, ma na-ejikarị ngwa na-achọ ike dị elu.

   • AISI 316L: Ụdị carbon dị ala nke AISI 316, na-enye mma weldability na nguzogide corrosion na gburugburu ebe siri ike.

   Ka ọkwa ọkwa igwe anaghị agba nchara dị elu, otú ahụ ka ike ndọtị na ike ibu nke eriri ahụ na-abawanye.

4. Ọnụọgụ nke waya na eriri
   Ọnụ ọgụgụ nke wires na eriri ọ bụla na ọnụ ọgụgụ nke eriri na eriri na-emetụta ike ya n'ozuzu ya. Ụdọ nwere ọtụtụ wires na strands n'ozuzu na-enye ike na mgbanwe dị mma, mana ọ nwere ike ibelata nkwụchi nke eriri ahụ na abrasion n'ihi na a na-ekpughe ebe elu elu ka ọ na-eyi.

5. Ihe nchekwa
   Nkeihe nchekwabụ ihe nrịbawanye etinyere n'ikike ibu gbakọrọ ọnụ iji kwụọ ụgwọ maka nrụgide na-atụghị anya ya, ọnọdụ gburugburu ebe obibi, na nchekwa nchekwa. A na-ahọrọkarị ihe nchekwa dabere n'ụdị ngwa ahụ. Ọmụmaatụ:

   • Mwube na Ngwuputa: A na-ejikarị ihe nchekwa nke 5: 1 (ya bụ, eriri ahụ kwesịrị inwe ike ijikwa okpukpu ise kachasị elu).

   • Ebuli na ibuli eluIhe nchekwa nke 6:1 ma ọ bụ 7:1 nwere ike dabara adaba, ọkachasị maka ọrụ ebuli elu ebe nchekwa dị mkpa.

Otu esi agbakọ ikike ibu eriri igwe anaghị agba nchara

Ugbu a na anyị ghọtara ihe ndị na-emetụta ike ibu, ka anyị gafere usoro nke ịgbakọ ya. Usoro izugbe maka ịgbakọ ike ibu nke eriri igwe anaghị agba nchara bụ:

Ikike ibu (kN) = Ike na-agbaji (kN)/Ihe nchekwa

Ebe:

• Na-agbaji Ike: Nke a bụ ike kachasị ma ọ bụ ibu nke eriri nwere ike idi tupu ya agbaji. Ndị nrụpụta na-enyekarị ya ma ọ bụ nwee ike gbakọọ ya site na iji ike nhịahụ nke ihe ụdọ na mpaghara obe ya.

• Ihe nchekwa: Dị ka a tụlere na mbụ, nke a bụ ụbara nke na-eme ka eriri ahụ nwee ike ijikwa ibu ndị a na-atụghị anya ya.

Enwere ike gbakọọ ike mgbaji nke eriri waya dịka ndị a:

Ike na-agbaji (kN) = Ike nchara nke igwe (kN/mm²) × Mpaghara-Ngalaba nke eriri (mm²)

Ihe atụ Mgbakọ nzọụkwụ site na nzọụkwụ

Ka anyị gaa na ngụkọ bụ isi maka ịghọta ike ibu nke eriri igwe anaghị agba nchara:

1. Kpebie ike tensile ihe onwunwe
   Ọmụmaatụ, AISI 316 igwe anaghị agba nchara nwere a ahụkarị tensile ike nke gburugburu2,500 MPa(MegaPascal) ma ọ bụ2.5 kN/mm².

2. Gbakọọ mpaghara Cross-Sectional nke eriri
   Ọ bụrụ na anyị nwere eriri na adayameta nke 10 mm, enwere ike gbakọọ mpaghara cross-section (A) nke eriri site na iji usoro maka mpaghara okirikiri:

   $A=\pi \times (d2)2A\; =\; \backslash pi\; \backslash \; ugboro\; \backslash \; aka\; ekpe(\backslash frac\; \{d\}\{2\}\backslash nri)^2$

   A=π × (2d) 2

   Ebee
   $dd$

   d bụ dayameta nke eriri. Maka eriri dayameta 10 mm:

   $A=\pi \times (102)2=\pi \times 25=78.5\; mm²A\; =\; \backslash pi\; \backslash \; ugboro\; \backslash \; akaekpe(\backslash frac\{10\}\{2\}\backslash right)^2\; =\; \backslash pi\; \backslash \; times\; 25\; =\; 78.5\; \backslash ,\; \backslash ederede\{mm²\}$

   A=π×(210)2=π×25=78.5mm²

3. Gbakọọ Ike Na-agbaji
   Iji ike tensile (2.5 kN/mm²) na mpaghara akụkụ (78.5 mm²):

   $Ịgbaji\; Ike=2.5\times 78.5=196.25\; kN\backslash text\; \{Ike\; Na-agbaji\}\; =\; 2.5\; \backslash \; times\; 78.5\; =\; 196.25\; \backslash ,\; \backslash text\{kN\}$

   Ike na-agbaji = 2.5×78.5=196.25kN

4. Tinye ihe nchekwa nchekwa
   Na-eche ihe nchekwa 5:1 maka ngwa ebuli elu n'ozuzu:

   $Ibu\; Ibu=196.255=39.25\; kN\backslash text\{Ike\; Ibu\}\; =\; \backslash frac\{196.25\}\{5\}\; =\; 39.25\; \backslash ,\; \backslash text\{kN\}$

   Ibu Ibu=5196.25=39.25kN

Ya mere, ikike ibu nke eriri igwe anaghị agba nchara 10 mm dayameta, nke sitere na AISI 316 igwe anaghị agba nchara, yana ihe nchekwa nke 5: 1, dị ihe dịka.39.25 kN.
