Thaum cov ntawv thov nce mus txog Euler load, qee zaum hu ua qhov tseem ceeb load, kem los nyob rau hauv lub xeev tsis ruaj khov. Nyob rau ntawm qhov load, qhov kev taw qhia ntawm lub slightest lateral quab yuam yuav ua rau kem ua tsis tau tejyam los ntawm dheev "dhia" mus rau ib tug tshiab configuration, thiab lub kem yog hais tias muaj buckled.
Vim li cas buckling tshwm sim hauv kab?
Buckling ntawm Kab yog daim ntawv ntawm deformation los ntawm axial- compression rog. Qhov no ua rau khoov ntawm kem, vim qhov tsis ruaj khov ntawm kab. Hom kev ua tsis tiav no yog nrawm, thiab yog li txaus ntshai. … Qhov no yuav tshwm sim ntawm qhov kev ntxhov siab tsawg dua qhov kev ntxhov siab kawg ntawm kab.
Yuav ua li cas thaum ib kab buckles?
Thaum lub load ncav cuag lub buckling theem kab yuav ua tsis tiav los ntawm randomly khoov ntawm ob sab uas muaj qhov loj dua qhov sib piv. Lwm txoj hauv kev los saib yog tias Euler buckling qee zaum hu ua Euler instability.
Kab kem puas yuav?
Lub beam lub sab hauv tsis kam khoov ua rau lub nqaj ntawm buckling. Txawm li cas los xij, ntawm qee lub sijhawm, lub sijhawm muaj peev xwm tsim los ntawm axial load yuav yog ntau dua lub sijhawm tiv thaiv sab hauv, thiab kab yuav buckle. Rau txhua kab, nws feem ntau xav tias yog buckling tshwm sim, tus qauv ua tsis tiav.
buckling load hauv kab yog dab tsi?
Buckling yog ib qho kev ua tsis tiav ntawm tus tswv cuab axially loadednyob rau hauv compression, nyob rau hauv tus nqi load tsawg dua lub compressive load-nqa peev ntawm tus tswv cuab. Lub axial compressive load sib xws rau hom kev ua tsis tiav no raug xa mus rau qhov tseem ceeb buckling load.
