Cov qauv Euler kem kwv yees qhov tseem ceeb buckling load ntawm kab ntev nrog pinned kawg. Euler formula is P cr=π 2 ⋅ E ⋅ I L 2 qhov twg E yog tus qauv ntawm elasticity nyob rau hauv (force/length2), Kuv yog lub sij hawm ntawm inertia (ntev 4), L yog qhov ntev ntawm kab.
Koj suav li cas buckling deflection?
Euler Buckling Theory
Nws pib yooj yim los ntawm kev ceeb toom tias lub sijhawm khoov sab hauv hauv ib sab loaded thiab deformed yog −Py qhov twg P yog lub compressive load thiab y yog kab deflection. So insert −Py in for M in the beam bending equation, EIy′′=M E I y″=M.
Euler's Theory of buckling yog dab tsi?
Euler txoj kev xav tau hais tias qhov kev ntxhov siab hauv kab vim kev thauj khoom ncaj qha me me piv rau kev ntxhov siab vim tsis ua haujlwm. Raws li cov lus no, ib qho qauv muab los xam qhov tseem ceeb buckling load ntawm kab.
buckling ratio yog dab tsi?
Qhov piv ntawm qhov tseeb rau qhov load ntawm qhov tshwm sim bucklingyog lub npe hu ua qhov sib piv ntawm ib daim ntawv. Kev sib piv siab buckling tuaj yeem ua rau ntau dhau ntawm cov nplooj ntawv uas tuaj yeem ua tsis tiav los ntawm kev tawm ntawm wrinkles.
K hauv buckling yog dab tsi?
A yog qhov chaw hla ntu, L yog qhov tsis txhawb nqa ntev ntawm kab, r yog lub vojvoog ntawm gyration ntawm ntu ntu, thiab E yog qhov elastic modulus ntawm cov khoom. K yog qhov ua tau zoo ntawm qhov ntev, thiabnyiaj rau cov xwm txheej kawg ntawm kab.
