Tsim thiab Kev Ntsuam Xyuas Ntawm Txoj Kev Ncaj Ncees Round Flexible Hinge_Hinge Kev Paub

Kho dua

Abstract:

Txhawm rau ua tiav lub pob khawm hloov tau nrog kev txhim kho yooj yim dua thiab siab dua qhov kev sib hloov, kev tsim tshiab rau lub pob khawm ncaj nraim tau tsim. Cov yooj yooj yim, precision, thiab qaug zog lub neej ntawm pob khawm tshiab no tau muab piv thiab tshuaj xyuas tiv thaiv ib qho kev sib tw ncaj ncaj pob khawm. Cov txiaj ntsig tau pom tias qhov tshiab ncaj ncig lub pob khawm hloov pauv tau nthuav tawm ntau dua kev hloov pauv thiab siab dua qhov tseeb dua piv rau cov pob khawm tsoos. Lub neej qaug zog ntawm ob lub pob khawm yog nyob ze rau qhov kawg. Zuag qhia tag nrho, lub pob khawm hloov pauv tshiab tau ua tiav cov pob khawm tsoos thiab ua tau raws li cov qauv tsim.

1.

Cov pob khawm yooj yim tau ua tiav ntawm kev tshawb fawb dav vim lawv cov kev siv hauv micro-electromechanical systems, precision instrumentation, thiab micromanipulation. Cov pob khawm no yog qhov me me, tsis muaj qhov sib txawv, tsis muaj kev sib txhuam ntawm cov neeg kho tshuab, thiab cov rhiab heev. Cov kws tshawb fawb tau pom muaj kev txaus siab rau kev tsim cov pob khawm hloov tau [1-3]. Cov yam ntxwv tseem ceeb ntawm cov pob khawm hloov tau muaj xws li kev nruj (qhov yooj yim), qhov tseeb, thiab cov yam ntxwv kev ntxhov siab [4-5]. Txij li cov pob khawm hloov tau yooj yim ua rau qaug zog tsis ua haujlwm piv rau cov qauv nruj, kev txheeb xyuas qaug zog yog tsim nyog thaum lub sij hawm tsim qauv [6-7].

Nyob rau hauv daim ntawv no, ib tug tshiab tsim rau ib tug ncaj voj yooj yooj yim pob khawm yog nthuav. Qhov yooj yim, precision, thiab qaug zog lub neej ntawm lub pob khawm no yog tshuaj xyuas siv cov khoom siv software Workbench 15.0. Qhov kev ua tau zoo ntawm lub pob khawm tshiab yog muab piv rau cov tsoos ncaj ncig lub pob khawm yooj yim.

2. Kev ntsuas kev ua haujlwm ntawm pob khawm

Txhawm rau tsim lub pob khawm hloov tau yooj yim, nws yog ib qho tseem ceeb los soj ntsuam nws cov yam ntxwv tseem ceeb. Cov kev ua haujlwm tseem ceeb ntawm lub pob khawm hloov tau muaj xws li yoog raws, qhov tseeb, thiab lub neej qaug zog.

2.1 Flexibility Analysis

Flexibility (tuaj yeem) yog qhov tsim qauv tseem ceeb rau cov pob khawm yooj yim. Qhov sib npaug (1) qhia tau hais tias thaum lwm yam tsis tas li, lub pob khawm me me (b) ua rau muaj kev hloov pauv ntau dua. Yog li ntawd, qhov tshiab ncaj ncig hloov pob khawm, nrog rau qhov dav dav dav (b1), nthuav tawm txhim kho qhov yooj yim. Finite element tsom xam siv Workbench 15.0 tau ua los xyuas qhov yooj ntawm ob lub pob khawm. Cov khoom siv tib yam, kev thauj khoom, thiab ciam teb raug siv rau ob lub pob khawm. Stainless hlau, nrog ib qho elastic modulus ntawm 190 GPa thiab Poisson tus piv ntawm 0.305, tau raug xaiv los ua cov khoom siv rau cov qauv pob khawm. Qhov ntev ntawm cov tsoos ncaj ncig lub pob khawm hloov tau yog: pob khawm ntev (a) = 30 mm, dav (b) = 10 mm, qhov siab (h) = 10 mm, thickness (t) = 1 mm, thiab arc radius (r ) = 4.5 hli
