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

Tsis zoo siv:

Saj zawg zog hinges tau nce cov muaj suab npe tseem ceeb hauv thaj chaw micro electromeChanical (mems). Daim ntawv no qhia txog hom tshiab ntawm cov pob khawm hloov tau, uas yog cov tog-ob tog-purthibe pob khawm. Leveraging Karl's thib ob, ib lub ntsiab lus hais txog cov qauv sib piv rau kev yoog raws li kev sib tw thiab elliptical hybrid yoog pob khawm tau raug npaj siab. Cov mis tau muab tau los ntawm kev txheeb xyuas cov ntsiab lus zoo thiab kev txheeb xyuas. Qhov cuam tshuam ntawm txhua qhov kev ntsuas ntawm cov unilateral hybrid flexible pob khawm ntawm nws yooj yim yog tshuaj xyuas. Tsis tas li ntawd, kev sib piv yog ua nrog ob-ob tog ncaj-voj-prant-plectible pob khawm thiab thauj khoom rhiab heev ntawm kev tsim qauv. Cov lus thov ntawm unilateral hybrid saj zuaj pob zeb hloov kho txoj kev tshiab rau kev tsim cov ntawv thov thiab cov chaw tsis zoo.

Kev tawm ntawm micro-electromechanical tshuab, aerospace engineering, thiab txheeb cais cov kev txwv ntawm kev ua kom nruj hauv kev tsim qauv thiab kev siv yuav tsum tau ua. Yooj Yim Suab Hluav Taws Xob Muaj ntau qhov txiaj ntsig zoo me me, tsis muaj kev sib txhuam me me, tsis muaj qhov khoob, thiab cov lus ceeb toom siab rhiab. Qhov no tau coj mus rau lawv cov kev qhuab qhia ntau yam, suav nrog cov tshuab, kev hlau, khoos phis tawj, kev tswj hwm, ntsuas kev tswj hwm tsis siv neeg. Cov ntsiab lus tseem ceeb ntawm kev yoog raws lub tshuab hloov tau yooj yim, uas tshem tawm cov lus pom ploj thiab kev rov qab ua ke, tso cai rau cov kev daws teeb meem ntau dua. Ib Leeg-Axis Fixed Hinges tau faib rau ntau yam duab, xws li arc, txhuas lub, ellipe, parabola, thiab hyperbola. Ntawm lawv, txoj kev ncaj-puag ncig thiab cov txhuas cov hom tau dav vim yog lawv cov qauv yooj yim. Txawm li cas los xij, hauv qee cov ntawv thov uas qhov chaw muaj tsawg, kev xaiv uas nyiam dua, nrhiav cov nqi hluav taws xob, kev ntsuas ntsuas qhov ntsuas thiab muab tso rau.

Txojkev:

Lub tsev ua raws li cov kev tshawb fawb ua ntej, txoj kev kawm tshiab ntawm hybrid fixed khawm, uas muab sib xyaw ua ke ntawm cov hybrid thiab unilateral yoog cov pob khawm. Qhov yooj yim hloov cov mis rau cov pob khawm no yog muab tau raws li Karl's thib ob yog qhia txog kev soj ntsuam zoo los ntawm kev tsom xam zoo. Txoj kev tshawb fawb kuj kuaj xyuas cov cawv ntawm ntau cov txheej txheem sib txawv ntawm qhov hloov pauv ntawm pob khawm.

Cov txiaj ntsig thiab kev sib tham:

Qhov kev hloov kho cov mis rau cov unilateral ncaj-voj-ellell-ellipse khawm qhia tau tias yooj yim yog nyob ntawm ob qho khoom siv thiab cov qauv teeb meem. Cov khoom siv tau los qhia tau tias tsis muaj peev xwm ua tau zoo rau cov pob khawm sib npaug, elllipse axis, ellipe axis, thiab tsawg kawg nkaus tuab tseem cuam tshuam. Los ntawm kev tsom xam, nws yog tau pom tias yooj yooj yim nyob rau hauv lub ellipse ntawm semi-me me ntawm thickness, thiab hloov tsis yog-linearly nrog sib txawv nrog kev sib txawv. Cov cawv ntawm cov tuab yam tsawg kawg ntawm kev yoog raws yog pom tias yog qhov tseem ceeb piv rau lwm yam.

Ib qho kev sib piv yog kos ntawm Unilateral Ncaj-Volripse-ellipse pob khawm thiab ob npaug ntawm ob lub voj voog-ellipse pob khawm hloov tau nyob rau hauv cov ntaub ntawv ua ntej. Yooj taus yog qhia tias yog qhov tseem ceeb tshaj plaws ntawm cov pwm sib npaug, thiab cov kev txheeb ze ua kom haum rau ob lub pob khawm tsim. Kev tsom xam pom tias lub unilateral hybrid flexible pob khawm hloov tau muaj peev xwm ntau dua thiab thauj cov kev tsim kho dua rau cov qauv ob. Qhov yooj ntawm cov unilateral hybrid saj lub pob khawm yog kwv yees li 1.37 lub sij hawm siab tshaj li ntawm cov khoom siv xyoob ntoo.

Txoj kev kawm no nthuav tawm cov kev tsom xam ntawm hybrid flexible pob khawm, ib qho hloov pauv pob khawm hloov pauv uas muaj cov txheej txheem kev cog lus. Cov kev hloov pauv ntawm cov khoom siv tau siv tau los ntawm cov kev tshawb xyuas zoo ntawm cov ntsiab lus, ua qhov yuam kev tsis pub dhau 8%. Kev cuam tshuam ntawm cov txheej txheem txheej txheem ntawm kev hloov tau yog tshuaj ntsuam, nrog cov tuab yam tsawg kawg nkaus ntawm cov pob khawm uas muaj peev xwm tshaj plaws. Tsis tas li ntawd, kev sib piv nrog ob tog hybrid flexible pob khawm zoo tshaj plaws ntawm kev tsim muaj peev xwm hloov pauv thiab thauj cov rhiab. Cov lus thov unilateral hybrid flexible pob khawm hloov kho tshiab rau cov kev thov engineering ntawm kev sib txuam ntawm kev lag luam.
