Dabtsi yog khoov, lub tensile thiab compressive nruj me ntsis tsom tsom thiab daim ntawv thov ntawm plaub rab sib chaws yooj ywm yoog pob khawm

Ntsiab lus: Kab lus no muab kev soj ntsuam ntawm cov khoom tawv ntawm plaub yam sib xyaw ua ke. Nws pib los ntawm kev ua kom muaj cov txheej txheem sib cais rau khoov pob tw, nro, thiab txuag kev nyuaj ntawm plaub sib npaug ntawm cov tshuab sib xws raws li cov ntaub ntawv. Kev siv cov qauv zoo, tus sau paub tseeb qhov tseeb tau muab cov khoom tawv nqaij tawv li cas muab cov cim ncaj ncaj nqaj pob khawm.

Cov kab lus ces sib piv thiab tshuaj xyuas lub zog txhav ntawm plaub sib txawv sib xyaw ua ke. Nws qhia tau tias elliptical ncaj nqaj Composite pob khawm muaj qhov tsawg tshaj plaws khoov thiab tensile txhav.

Tom ntej no, tus sau txheeb xyuas lub zog txhav ua tau zoo ntawm cov pob qij txha t-puab uas siv cov txheej txheem zoo. Nws pom tias kev them nyiaj ntxiv thiab deformation muaj peev xwm ntawm kev sib koom tes T-zoo li hloov tau tsim ntawm elliptical ncaj nqaj sib dhos yog qhov muaj zog tshaj.

Saj zawg zog hinges yog dav siv nyob rau hauv cov ntawv thov uas yuav tsum muaj angular tsheb me me thiab high-precision tig. Lawv tshem tawm cov cua mus ncig thiab tshuab sib txhuam thaum muaj kev kis. Tiffness yog qhov tseem ceeb tshaj plaws taw qhia ntawm pob khawm uas nws muaj peev xwm tiv thaiv kev thauj khoom sab nraud thiab kev hloov pauv ntawm cov kinematic khub.

Cov kab lus hais tias yav dhau los cov kev tshawb fawb tau muab cov qauv ntawm cov qauv sib cav rau kev laij cov pob taws uas hloov tau. Hauv kev tshawb fawb no, tus sau siv cov txheej txheem yooj yim ntawm cov mechanics kom tau txais cov kab lus piav qhia ntau yam. Txawm li cas los xij, vim muaj qhov ntev ntawm geometric ntawm qhov tseeb yoog raws li kev xav ntawm txoj kev xav tau ua rau txoj kev xav tau feem ntau ua haujlwm rau kev kawm lawv cov tawv nqaij tawv.

Raws li lub voj voos ncaj nqaj pob khawm yooj ywm, tus sau cov tswv yim ncaj qha pob khawm: ellotical ncaj nqaj cable, thiab hyperbolic ncaj nqaj Cov txheej txheem txhav tawv muaj teeb rau cov plaub no ntawm cov pob khawm no yog muab tau los, thiab lawv cov khoom tawv ncauj tau muab piv thiab raug txheeb xyuas.

Txhawm rau ua kom pom cov ntawv thov no, cov ntawv tshawb fawb ntawm cov khoom nruj ntawm t-puab cov pob qij txha siv plaub yam sib xyaw ua ke. Cov txiaj ntsig qhia tau tias kev sib koom ua T-zoo nkauj tsim tau ntawm elliptical txoj kev them nyiaj hluav taws xob ncaj pob khawm qhov chaw muaj zog tshaj plaws.

Hauv kev xaus, cov kev tshawb fawb no tau muaj txiaj ntsig zoo rau hauv cov chaw tawv muaj zog ntawm ntau hom kev sib xyaw ntawm cov tshuab sib xyaw. Qhov kev tshawb pom tuaj yeem qhia tus qauv tsim thiab cov ntawv thov ntawm cov pob khawm hloov tau nyob rau ntau yam kev lag luam, tshwj xeeb hauv kev siv tau sib sau thiab kev sib txhuam tsawg.
