Daim kab xev ntsuas lub caij nplooj ntoos hlav yog ib feem zoo ib yam li cov kab xev ntsuas, thiab yog ib txheej qhib cylindrical plhaub. Lub pob khawm tuaj yeem tsim thiab tsim los ntawm kev siv nws lub plhaub buckling zog. Cov pob khawm no muaj cov khoom siv tshwj xeeb. Nws tuaj yeem siv lub zog elastic zog sib sau ua ke thaum lub sij hawm folding kom paub qhov tsis siv neeg unfolding ntawm cov qauv yam tsis tas yuav tsum tau rau lwm yam khoom siv fais fab; Tom qab nthuav tawm, nws tuaj yeem tso siab rau nws tus kheej rigidity. tsis tas yuav tsum muaj cov khoom siv xauv ntxiv. Xws li hinges tuaj yeem siv rau hauv qhov chaw loj ntawm cov qauv siv tau, xws li cov hnub ci tis tis.
Cov ntsiab lus geometric thiab cov khoom siv ntawm steel daim kab xev caij nplooj ntoos hlav, cov duab geometric ntawm cov kab xev hlau yog lub plhaub qhib cylindrical nrog rau qee qhov ntev, thiab nws cov ntsiab lus geometric suav nrog cov tuab ntawm daim kab xev t, lub vojvoog ntawm curvature R, lub kaum sab hnub. thiab qhov ntev L. Cov ntsiab lus geometric no yuav cuam tshuam rau cov khoom siv ntawm cov kab xev ntsuas. Cov khoom tseem ceeb muaj feem xyuam rau cov khoom siv kho tshuab muaj xws li elastic modulus E thiab Poisson tus piv. Hauv kev txheeb xyuas hauv qab no, peb siv lub elastic modulus E li , thiab Poisson tus piv li 0.3.
Lub pob khawm-tsav lub hnub tis nthuav dav heev, tab sis qhov torsional nruj tom qab lub pob khawm yog qhov tsis txaus thiab yuav tsum tau txhim kho. Tsis tas li ntawd, vim lub me me elastic modulus ntawm steel daim kab xev ntsuas cov khoom, nws lub zog tsav yog txwv, yog li nws tseem nyuaj rau siv nyob rau hauv loj solar panels. Txij li thaum muaj qhov sib txawv loj hauv pob khawm, qhov kev vibration loj yuav raug tsim, yog li cov qauv tsim ntawm pob khawm yuav tsum tau txhim kho.
