Me pēhea te tatau i te kaha utaina o te taura waea maitai kore waikura

I te wā e whiriwhiri ana i ngā taura waea kowiri tira mō ngā mahi ahumahi, ko tētahi o ngā mea tino nui hei whakaaroaro ko ō rātoute kaha kawengaAhakoa kei te whakamahia te taura waea i roto ihiki, te hiki, tōia, rāneite wirimō ngā tono, me āhei ki te whakahaere haumaru i ngā kawenga e tumanakohia ana. He mea nui te mārama ki te tatau i te kaha kawenga o te taura waea kowiri tira hei whakarite i te haumaru, te pono, me te whai huatanga o āu mahi. I roto i tēnei aratohu, ka whakamāramahia e mātou me pēhea te tatau i te kaha kawenga o ngā taura waea kowiri tira, me te whai whakaaro ki ngā mea nui pēnei i te hanganga taura, te kounga rauemi, me ngā āhuatanga haumaru.

He aha te kaha kawenga o te taura waea kowiri tira?

Tete kaha kawengaKo te taumaha mōrahi o te taura waea, ko te kaha rānei ka taea e te taura te pupuri me te haumaru me te kore e pakaru. Ka whakawhirinaki tēnei kaha ki ngā āhuatanga maha pērā i te taurawhānui, hanganga, taumata rauemi, mengā tikanga whakahaereMā te whakatau tata, te hipa rānei i te kaha kawenga ka arahi pea ki ngā rahunga nui, nō reira he mea nui kia tatauhia te kaha kawenga tika i mua i te whakamahinga.

Ngā Take Matua e Pā Ana ki te Kaha Utaina

1. Te Diameter o te Taura
   Ka pā tika te whānui o te taura waea ki tōna kaha kawenga. Ka taea e ngā taura whānui te kawe i ngā kawenga taumaha nā te whānui o te mata, engari he pai ngā taura iti mō ngā kawenga māmā. Ka piki ake te kaha kawenga i te pikinga o te whānui o te taura, engari ka piki ake hoki te taumaha me te ngāwari o te taura.

2. Te Hanga Taura
   He maha ngā momo hanganga o ngā taura waea kowiri tira, e kiia nei ko ngā taurahangangaHei tauira, heHanganga 6×19E ono ngā aho, e 19 ngā waea kei roto i ia aho. Ka pā te momo hanganga ki te ngāwari, te kaha, me te ātete ki te kakahu o te taura. I te nuinga o te wā, he ngāwari ake ngā taura he maha ngā aho engari he iti ake te kaha kawenga ki te whakataurite ki ngā taura he iti ake ngā aho.

3. Taumata Rauemi
   Ko te kounga o te kowiri tira e whakamahia ana i roto i te taura waea ka pā ki tōna kaha kume, ā, nō reira, ki tōna kaha kawenga. Ko ngā momo noa e whakamahia ana mō ngā taura waea kowiri tira:

   • AISI 304E mōhiotia ana mō tōna ātete ki te waikura engari he iti ake tōna kaha kume ki te whakaritea ki ētahi atu momo.

   • AISI 316He ātete pai ki te waikura, inā koa i roto i ngā taiao moana, ā, e whakamahia whānuitia ana i roto i ngā tono e hiahia ana kia kaha ake.

   • AISI 316LHe putanga waro-iti o te AISI 316, e whakarato ana i te kaha whakarewa pai ake me te ātete ki te waikura i roto i ngā taiao uaua.

   Ka teitei ake te kounga o te maitai kore waikura, ka nui ake te kaha kume me te kaha kawenga o te taura.

4. Te maha o ngā waea me ngā aho
   Ka pā te maha o ngā waea i ia miro me te maha o ngā miro i roto i te taura ki tōna kaha whānui. Ko te taura he maha ngā waea me ngā miro ka nui ake te kaha me te ngāwari, engari ka whakaiti pea i te ātete o te taura ki te karawarawa nā te nui ake o te mata e pāngia ana e te kakahu.

5. Tauwehenga Haumaru
   Teāhuatanga haumaruhe whakarea e whakamahia ana ki te kaha kawenga kua tatauhia hei whakaaro mō ngā ahotea ohorere, ngā āhuatanga taiao, me ngā whakaaro haumaru. Ko te tauwehe haumaru ka whiriwhiria i runga i te āhua o te tono. Hei tauira:

   • Te hanga me te keriKo te tauwehenga haumaru o te 5:1 (arā, me taea e te taura te pupuri i te kawenga e rima ngā wā o te kawenga mōrahi e tumanakohia ana) te mea e whakamahia whānuitia ana.

   • Te hiki me te hikiTērā pea he tika te tauwehenga haumaru o te 6:1, 7:1 rānei, inā koa mō ngā mahi hiki taonga nui ina he mea nui te haumaru.

Me pēhea te tatau i te kaha utaina o te taura waea maitai kore waikura

Nā te mea kua mārama tātou ki ngā āhuatanga e pā ana ki te kaha kawenga, me titiro tātou ki te tukanga tatau. Ko te tātai whānui mō te tatau i te kaha kawenga o te taura waea kowiri tira ko:

Te Kaha Utaina (kN)=Te Kaha Pakaru (kN)/Te Tauwehe Haumaru

Kei hea:

• Te Kaha PakaruKoinei te kaha, te kawenga rānei mōrahi ka taea e te taura te tu atu i mua i tōna whati. Ko te tikanga ka whakaratohia e te kaihanga, ka taea rānei te tatau mā te whakamahi i te kaha kume o te rauemi taura me tōna horahanga whakawhiti.

• Tauwehenga HaumaruE ai ki te kōrero i mua ake nei, he whakarea tēnei hei whakarite kia taea e te taura te tu atu i ngā kawenga ohorere.

Ka taea te tatau i te kaha whati o te taura waea penei:

Kaha Pakaru (kN)=Kaha Kume o te Rino (kN/mm²)×Horahanga Whakawhiti o te Taura (mm²)

Tauira Tātaitanga Hipanga-i-te-Taumata

Me titiro tātou ki tētahi tātaitanga taketake hei mārama ki te kaha kawenga o tētahi taura waea kowiri tira:

1. Whakatauhia te Kaha Kume Rauemi
   Hei tauira, ko te kaha kume o te maitai kore waikura AISI 316 he tata ki te2,500 MPa(MegaPascal) rānei2.5 kN/mm².

2. Tātaihia te horahanga whakawhiti o te taura
   Mena he taura tā tātou me tete whānui o te 10 mm, ka taea te tatau i te horahanga whakawhiti-wāhanga (A) o te taura mā te whakamahi i te tātai mō te horahanga o te porowhita:

   $A=\pi \times (d2)2A\; =\; \backslash pi\; \backslash times\; \backslash left(\backslash frac\{d\}\{2\}\backslash right)^2$

   A=π×(2d​)2

   Kei hea
   $dd$

   Ko d te whānui o te taura. Mō te taura 10 mm te whānui:

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

   A=π×(210​)2=π×25=78.5mm²

3. Tātaihia te Kaha Pakaru
   Mā te whakamahi i te kaha kume (2.5 kN/mm²) me te horahanga whakawhiti-wāhanga (78.5 mm²):

   $Kaha\; Pakaru=2.5\times 78.5=196.25\; kN\backslash text\{Kaha\; Pakaru\}\; =\; 2.5\; \backslash times\; 78.5\; =\; 196.25\; \backslash ,\; \backslash text\{kN\}$

   Kaha Pakaru=2.5×78.5=196.25kN

4. Whakamahia te Tauwehe Haumaru
   Ki te whakaaro he 5:1 te tauwehenga haumaru mō te mahi hiki whānui:

   $Te\; Kaha\; Utaina=196.255=39.25\; kN\backslash text\{Te\; Kaha\; Utaina\}\; =\; \backslash frac\{196.25\}\{5\}\; =\; 39.25\; \backslash ,\; \backslash text\{kN\}$

   Te Kaha Utaina=5196.25​=39.25kN

Nō reira, ko te kaha kawenga o tēnei taura waea maitai kore waikura he 10 mm te whānui, i hangaia mai i te maitai kore waikura AISI 316, me te tauwehenga haumaru o te 5:1, tata ki39.25 kN.

Te Hiranga o te Tātaitanga Tika o te Pūmanawa Utaina

Mā te tatau tika i te kaha kawenga ka taea e te taura te tu atu i te kawenga nui rawa atu me te kore e tūpono ki te pakaru. Mā te uta nui rawa o te taura waea ka pā he kino kino, tae atu ki te whati o te taura, te pakaru o ngā taputapu, ā, ko te mea tino kino, ko ngā aituā. He mea nui kia whai i ngā aratohu haumaru me te whakaaro ki ngā taurangi pēnei i ngā āhuatanga taiao, te pakaru me te haehae, me te tawhito o te taura.

Hei tāpiritanga, he mea nui kia tirotirohia me te tiaki tonu ngā taura waea kowiri tira kia mau tonu ai ō rātou kaha ki te kawe kawenga.
