Square tube VS akụkụ anọ tube, kedu udi ka inogide?
Ọdịiche arụmọrụ dị n'etititube akụkụ anọnatube squaren'ime ngwa injinia kwesịrị ka enyocha ya nke ọma site n'ọtụtụ ụzọ igwe dị ka ike, isi ike, nkwụsi ike, na ikike ibu.
1. Ike (ehulata na torsion eguzogide)
Ike na-ehulata:
tube akụkụ anọ: Mgbe edobere ibu na-ehulata n'akụkụ akụkụ ogologo (ntụziaka ịdị elu), oge inertia nke ngalaba ahụ buru ibu, na nguzogide na-ehulata dị mma karịa nke tube square.
Dị ka ihe atụ, ekwe ike nke 100 × 50mm akụkụ anọ tube na ogologo akụkụ direction bụ elu karịa nke 75 × 75mm square tube.
tube square: Oge inertia bụ otu ihe ahụ n'akụkụ niile, na arụmọrụ na-ehulata bụ ihe atụ, ma uru ya na-adịkarị obere karịa nke ogologo akụkụ akụkụ akụkụ anọ nke akụkụ anọ n'okpuru otu akụkụ nke akụkụ ahụ.
Nkwubi okwu: Ọ bụrụ na ntụziaka ibu ahụ doro anya (dịka nhazi beam), tube rectangular ka mma; ọ bụrụ na ntụzịaka ibu ahụ na-agbanwe agbanwe, tube square na-emeziwanye.
Ike Torsion:
Mgbochi na-adịgide adịgide nke tube square dị elu, nkesa nkesa nrụgide na-edozi ahụ bụ otu, na nkwụsị nke ọkpụkpụ dị mma karịa nke tube rectangular. Dị ka ihe atụ, na torsion eguzogide nke 75 × 75mm square tube bụ budata ike karịa nke 100 × 50mm akụkụ anọ tube.
Mkpebi: Mgbe ibu torsional na-achịkwa (dị ka ogwe nnyefe), tubes square dị mma.
2. Isi ike (ike mgbochi deformation)
Isi ike na-ehulata:
Isi ike dabara na oge inertia. Ọkpụkpụ akụkụ anọ nwere nkwụsi ike dị elu n'akụkụ akụkụ ogologo, nke kwesịrị ekwesị maka ọnọdụ ndị dị mkpa iji guzogide ntụgharị nke unidirectional (dị ka akwa akwa).
tubes square nwere isi ike bidirectional symmetrical ma dabara maka ibu multidirectional (dịka ogidi).
Nkwubi okwu: Ihe siri ike chọrọ dabere na ntụziaka ibu. Họrọ tubes akụkụ anọ maka ibu unidirectional; họrọ tubes square maka ibu bidirectional.
3. Nkwụsi ike (nkwụsị nkwụsị)
Mgbochi mpaghara:
Ọkpụkpọ akụkụ anọ na-enwekarị oke obosara-na-ọkpụrụkpụ, na akụkụ ndị nwere mgbidi na-adịkarị mfe nchikota mpaghara, ọkachasị n'okpuru mkpakọ ma ọ bụ ibu shi.
Ọkpụkpọ square nwere nkwụsi ike dị n'akụkụ ka mma n'ihi akụkụ cross-symmetrical ha.
Mkpokọta mkpokọta (Euler buckling):
Ibu nchikota jikọtara ya na radius kacha nta nke gyration nke ngalaba obe. Oghere nke gyration nke tubes square bụ otu n'akụkụ niile, ebe radius nke gyration nke tubes akụkụ anọ dị na akụkụ dị mkpirikpi dị ntakịrị, na-eme ka ha dịkwuo mfe ịmalite.
Mkpebi: A na-ahọrọ tubes square maka ndị òtù mkpakọ (dị ka ogidi); ọ bụrụ na a na-amachibido akụkụ akụkụ ogologo nke tube rectangular, ọ nwere ike ịkwụ ụgwọ site na imewe.
4. Ikike ibu (axial na jikọtara ibu)
Mkpakọ axial:
Ikike ibu nwere metụtara mpaghara obe na oke ịdị gịrịgịrị. N'okpuru otu ebe a na-agafe agafe, tubes square nwere ikike ibu dị elu n'ihi nnukwu ntụgharị ntụgharị ha.
Ibu ejikọtara ọnụ (nchịkọta ọnụ na ịgbada):
tubes akụkụ anọ nwere ike iji ohere nke nhazi kachasị mma mgbe ntụzịaka oge na-ehulata doro anya (dịka ibu kwụ ọtọ n'akụkụ ogologo); tubes square dabara adaba maka oge na-ehulata bidirectional.
5. Ihe ndị ọzọ
Iji ihe eji eme ihe:
Ọkpụkpụ akụkụ anọ na-arụ ọrụ nke ọma ma chekwaa ihe mgbe etinyere ya na-ehulata unidirectional; square tubes ndị ọzọ echekwa n'okpuru multi-directional ibu.
Mma njikọ:
N'ihi symmetry nke tubes square, njikọ ọnụ (dị ka ịgbado ọkụ na bolts) dị mfe; tubes akụkụ anọ kwesịrị ịtụle ntụzịaka.
Ọnọdụ ngwa:
tubes akụkụ anọ: ogwe ụlọ, ogwe aka crane, chassis ụgbọ ala (ntụziaka ibu doro anya).
tubes square: ogidi ụlọ, oghere oghere, okpokolo agba n'ibu (ibu ụzọ ọtụtụ).
