Elastic-yas flexural buckling ntawm endurance panels

Elastic-yas flexural buckling ntawm endurance panels

Thaum lub rooj tsavxwm ruaj khov nyob rau hauv tus ncej yog nyob rau hauv hnyav load, nws muaj peev xwm deform nyob rau hauv ib tug yoj zoo li raws li nws dav axis, thiab cov phab ntsa ntawm cov khoom board yuav buckling. Qhov no yog hu ua elastic buckling vim hais tias thaum lub load raug tshem tawm, daim ntawv yuav rov qab mus rau nws lub qub qub yam tsis muaj kev puas tsuaj mus tas li.

Yog hais tias peb txuas ntxiv mus nce qib load, daim ntawv yuav deflect mus txog rau thaum nws nws thiaj li buckles (yas buckling) ua rau puas daim ntawv mus tas li. Lub ntsiab lus ntawm deflection ntawm daim ntawv yog khoov yog hu ua buckling deflection, uas yog ib qho kev ua haujlwm ntawm geometry ntawm daim ntawv thiab tus nqi ntawm cov khoom nws muaj. Nyob rau hauv lub sij hawm ntev loads, cov ntaub ntawv khoom tuaj yeem pib khoov

Rau qhov tob uas tsis ua rau daim ntawv khoov (xws li elastic lossis yas), tab sis nyob rau hauv qhov kev thauj khoom tas li, cov teebmeem nkag tuaj yeem ua rau muaj kev nce hauv deflection dhau sijhawm, uas tuaj yeem ua rau buckling tsis ua haujlwm.
