1. Tlhahlobo ea index ea ts'ebetso ea square tube - polasetiki
Plasticity e bolela bokhoni ba lisebelisoa tsa tšepe ho hlahisa deformation ea polasetiki (deformation e sa feleng) ntle le tšenyo tlas'a mojaro.
2. Tlhahlobo ea index ea ts'ebetso ea square tube - boima
Ho thatafala ke pontšo ea ho lekanya ho thatafala le bonolo ba lisebelisoa tsa tšepe. Hajoale, mokhoa o sebelisoang ka ho fetesisa oa ho lekanya boima ba tlhahiso ke mokhoa oa ho thatafala oa indentation. E sebelisa indenter e nang le geometry e itseng ho hatella ka holim'a lisebelisoa tsa tšepe tse lekiloeng tlas'a mojaro o itseng, 'me e lekanya boleng ba eona bo thata ho latela tekanyo ea ho indentation.
Mekhoa e sebelisoang hangata e kenyelletsa Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) le Vickers hardness (HV).
3. Tlhahlobo ea index ea ts'ebetso ea square tube - mokhathala
Matla, polasetiki le boima bo boletsoeng ka holimo ke matšoao 'ohle a thepa ea mechine ea tšepe tlas'a mojaro o tsitsitseng. Ebile, likarolo tse ngata tsa mochini li sebetsa tlas'a mojaro oa cyclic, moo mokhathala o tla ba teng.
4. Tlhahlobo ea index ea ts'ebetso ea "square tube" - boima ba phello
Mojaro o sebetsang karolong ka lebelo le leholo o bitsoa " impact load", 'me bokhoni ba tšepe ba ho hanela ho hloleha tlas'a mojaro oa tšusumetso bo bitsoa ho tiea ha tšusumetso.
5. Tlhahlobo ea index ea ts'ebetso ea phala ea lisekoere - phala e matla ea lisekoere tsa tšepe, phala e teteaneng ea lisekoere tsa tšepe, phala e kholo ea lisekoere tsa tšepe, phala ea tšepe e se nang moeli, phala e tlase ea tšepe ea alloy, 135 * 135 * 10 square steel pipe, phala ea tšepe e sekoere bakeng sa crane ea tora. , Q345B low alloy square steel pipe, 20 # seamless lisekoere tšepe pipe
Matla a bolela ho hanyetsa ha thepa ea tšepe ho hlōleha (deformation e feteletseng ea polasetiki kapa fracture) tlas'a mojaro o tsitsitseng. Kaha mekhoa ea ketso ea mojaro e kenyelletsa tsitsipano, khatello, ho kobeha le ho kuta, matla a boetse a arotsoe ka matla a tsitsitseng, matla a khatello, matla a flexural le matla a ho kuta. Hangata ho na le kamano e itseng pakeng tsa matla a sa tšoaneng. Ka kakaretso, matla a tensile a sebelisoa e le sesupo sa matla a mantlha.
