Kev hloov kho yooj yim thiab kev ua tau zoo ntawm ib leeg-ob tog ncaj ncaj-voj voog-ellipse hybri1

Tsis zoo siv:

Saj zawg zog hinges ua lub luag haujlwm tseem ceeb hauv thaj teb ntawm micro-electromeChanical systems (MEMS). Daim ntawv no nthuav qhia cov khawm tshiab hloov tau yooj yim ntawm cov tog raj hu ua ib tog-voj voog-ellipse pob khawm hloov tau. Qhov hloov pauv tau ntawm cov pob khawm no yog xam siv Karl lub thib ob, thiab cov txiaj ntsig tau siv tau los ntawm kev tsom xam cov ntsiab lus zoo. Cov txheej txheem tsis ntawm lub pob khawm tau raug tshuaj xyuas kom txiav txim siab lawv cov cawv ntawm nws qhov yooj. Ib qho kev sib piv tseem tau ua nruab nrab ntawm ib leeg-tog thiab ob-ob tog ncaj-voj-pawm-Versions, thiab nws tau xaus lus tias cov tog rooj sib hloov pauv thiab thauj cov rhiab. Zuag qhia tag nrho, ib sab-sided hybrid saj lub pob khawm muab cov lus thov cog lus rau kev cog lus thiab cov kev hloov kho tshiab hauv kev tsim khoom lag luam.

Hauv kev hloov kho thev naus laus zis sai sai ntawm cov tshuab micro-electromeachanical, aerospace, thiab roj ntsha engineering tsis txaus kom tau raws li kev tsim qauv thiab kev siv yuav tsum tau ua. Kev hloov kho mechanisms, nrog lawv qhov loj me, tsis muaj kev sib txhuam ntawm cov kev coj ua ntau yam, suav nrog cov cuab yeej tseem ceeb, suav nrog kev ntsuas ntau yam, thiab kev ntsuas tsis siv neeg. Cov ntsiab lus tseem ceeb ntawm kev hloov kho tshuab hloov tau yog qhov hloov kho tshiab thiab kev rov qab los ntawm tus kheej kom tshem tawm cov lus tsa suab ploj, yog li ua tiav cov kev daws teeb meem ntau dua. Ib Leeg-Axis hloov tau cov pob khawm hloov tau yooj yim raws li cov duab sib txawv, xws li Arc, txhuas lub, ellipe, hom parabola, thiab hyperbola hom. Ntawm cov no, txoj kev ncaj-puag ncig thiab coj lub tshuab hinges yog siv dav vim lawv cov qauv yooj yim. Txawm li cas los xij, qee kis uas qhov chaw tau txiav txim siab, qhov xav tau rau cov kev siv tshuab hluav taws xob tau ua rau muaj kev ntsuas ib leeg, uas tau pom cov kev ntsuas dav dav thiab muab tso rau. Lub tsev raws li qhov zoo ntawm hybrid hloov kho pob khawm, uas yog qhov kev thov kom haum rau cov pob zeb engineering ntawm conventable hinges nrog compact qauv thiab loj chaw tsis sib haum.

Yooj Yim Kev Xam Ntawm Cov Unilateral Ncaj-Vajvoog-ellipse Hybrid Flexible Pob Khawm Pob Kinge:

UNILATEAL ncaj-voj voog-ellipse-ellipse hybrid flexible pob khawm sib xyaw ua ke thiab ib nrab ntawm cov pob zeb ncaj ncees. Nws cov teeb meem geometric suav nrog khawm khawm (B), tuab tuab (m), Kev ntsuas ntawm lub pob khawm hloov tau yooj yim yog ua raws li cov nqaj me me, nrog txoj cai excucation thiab khoov deformation los ntawm kev quab yuam thiab lub sijhawm. Tus ntawm cov roj axial txiav txim siab, thaum lub sij hawm shear thiab torsion cuam tshuam yog tsis saib xyuas. Raws li qhov thib ob theorem ntawm cov kab ke, kev sib raug zoo ntawm pob khawm sib txawv ntawm taw tes rau ntawm taw tes 1 thiab cov khoom siv thov tau txiav txim siab. Qhov kev hloov kho cov mis tau muab tau los ntawm qhov kev sib raug zoo thiab cov kev saib xyuas ntawm cov pob khawm hla kev. Los ntawm kev suav sib sau ua ke, hloov tau ntawm unilateral ncaj-voj-pbripse pob khawm muaj peev xwm tau txais.

Piv txwv li kev xam thiab cov lus qhia tseeb:

Qhov piv txwv piv txwv yog ua tau siv cov kev hloov pauv tau los ntawm cov khoom sib txawv rau cov txiaj ntsig sib txawv ntawm lub ellipse (n) ntawm lub ellipse. Cov txiaj ntsig tau muab piv nrog kev txheeb xyuas cov ntsiab lus zoo (fea) cov txiaj ntsig los txheeb xyuas qhov tseeb ntawm cov qauv ntawm cov mis. Qhov yuam kev ntawm ob pawg ntawm cov txiaj ntsig tau pom tias tsawg dua 8%, lees paub qhov tseeb ntawm cov qauv mis.

Kev Ntsuas Xyuas ntawm Unilateral Ncaj-Vaj Huam Sib-ellipse Hybrid Flexible Pob Khawm Pob Khawm:

Qhov yooj yooj yim ntawm cov pob khawm yog cuam tshuam los ntawm nws cov khoom siv thiab cov qauv tsis zoo. Qhov yooj yim hloov cov mis qhia tias Elastic Modulus (e) yog inversely proportional rau lub pob khawm (b). Lwm yam tsis zoo, xws li txoj kev ncaj-lub vojvoog radius (m), semi-loj axis ntawm ellipse (n), kuj cuam tshuam rau qhov yooj yim. Kev txheeb xyuas qhov hloov kho cov mis ua kom tiav hais tias nws cov kev txwv yog cov kev nkag siab zoo tshaj plaws hauv cov pob khawm tsawg kawg nkaus (t) ntawm pob khawm.

Kev Ua Tau Zoo Sib piv nrog Bilateral Ncaj-Vajvoog-ellipse Hybrid Flexible Pob Khawm Pob Khawm:

Lub rooj sib npaug ncaj-lub voj voog-ellipse-ellipse hybrid saj zuaj pob khawm yog muab piv nrog ob-ob-tog-pranted ncaj ncaj khawm nyob rau hauv cov ntaub ntawv. Qhov yooj yooj yim sib piv yog siv ua qhov ntsuas kev ua tau zoo, txhais tau tias yog qhov sib piv ntawm cov kev hloov pauv hloov mus rau cov khoom siv ua kom yooj yim. Cov txiaj ntsig qhia tau hais tias cov unilateral hybrid flexible pob khawm muab kev sib hloov zoo dua thiab cov khoom siv dag zog rau cov pob khawm sib tsoo.

Cov lus thov ntawm cov hom tshiab ntawm cov pob khawm hloov tau, cov unilateral hyebrigle pob khawm uas xav tau cov qauv kev ua kom sib xyaw thiab cov chaw tsis sib haum loj. Qhov kev hloov kho cov mis tau muab tau los ntawm Karl's thib ob ntawm kev ntsuas thiab siv tau los ntawm cov kev tshawb fawb finite. Cov txheej txheem tsis pom ntawm lub pob khawm pom tias cuam tshuam rau nws qhov yooj yim, nrog cov tuab yam tsawg kawg nkaus uas muaj qhov cuam tshuam loj tshaj plaws. Lub pob khawm sib xyaw ua tiav zoo dua li cov pob khawm sib hloov thiab thauj cov rhiab. Zuag qhia tag nrho, cov unilateral hybrid saj lub pob khawm muaj kev cog lus rau cov kev cia siab rau ntau yam engineering rau ntau yam engineering.
