Kev Tshaj Tawm ntawm Cov Ntsiab Lus:

Peb tau txheeb xyuas kom meej thiab txhais tau tus qauv tshiab rau cov"dynamic txiav efficiency"ntawm laparoscopic txiav hniav. Los ntawm kev sib koom ua ke ntawm cov kua dej sib xyaw ua ke, kev tshawb fawb biomechanical ntawm cov ntaub so ntswg, thiab cov txheej txheem micro- ua tiav, peb tau ua tiav qhov zoo ntawm cov hniav ntug geometry, cov kua dej ntawm cov nti tshem tawm grooves, thiab tag nrho cov qauv sib npaug. Qhov no ua rau peb cov hniav tsis yog tsuas yog ntse nyob rau hauv lub xeev zoo li qub, tab sis kuj ua kom tiav qhov siab tshaj plaws txiav efficiency, txo cov ntaub so ntswg puas, thiab xyuas kom meej nti nti tshem tawm thaum lub sij hawm siab - kev sib hloov ceev. Nws tau rov txhais cov txheej txheem engineering rau kev txiav kom zoo thiab muaj kev nyab xeeb.

Kev tshawb nrhiav thiab kev txhim kho keeb kwm mob ntshav qab zib:

Cov qauv tsim ntawm kev txiav cov hniav feem ntau yog raws li kev paub dhau los, thiab tsis muaj kev tshawb fawb txog qhov tseeb ntawm kev txiav thiab nti tshem tawm cov txheej txheem thaum lub sij hawm siab - kev sib hloov ceev. Cov teeb meem tshwm sim muaj xws li: thaum lub sij hawm txiav, cov ntaub so ntswg yog overly stretched es tsis zoo txiav, ua rau muaj kev pheej hmoo ntawm los ntshav; cov ntaub so ntswg txiav (tshwj xeeb tshaj yog cov ntaub nplaum nplaum) nws yooj yim rau txhaws lub taub hau ntawm lub taub hau lossis lub raj nqus dej, ua rau muaj kev cuam tshuam ntawm kev phais, thiab tus kws kho mob yuav tsum tau rov qab yaug thiab ntxuav; cov hniav tuaj yeem vibrate ntawm kev sib hloov ceev, cuam tshuam rau kev ua haujlwm zoo thiab raug, thiab txawm tias ua rau muaj kev sib tsoo thiab raug mob rau cov ntaub so ntswg noj qab haus huv. Cov kws kho mob xav tau ib"ntse"hniav uas tuaj yeem" nquag"tuav, txiav txiav, thiab"ua tau zoo"thauj cov ntaub so ntswg, nrog rau tag nrho cov txheej txheem ntws smoothly zoo li ib tug ntws ntws.

Core Technological Innovation:

Peb qhov kev tsim kho tshiab yuav txhawb nqa cov hniav tsim los ntawm cov"Static Geometry"dimension rau qhov"dynamic system"qhov ntev:

• Optimization ntawm Txiav Ntug Geometry:Peb tsis tsuas yog ua raws li qhov kawg sharpness (nyias txiav npoo yog nquag chipping thiab cracking), tab sis tsim"micro{0}}toothed"los yog"ntau-level inclined nto"Composite txiav ntug. Los ntawm kev txheeb xyuas cov ntsiab lus finite, peb txhim kho lub kaum sab xis txiav, rake lub kaum sab xis, thiab lub kaum sab xis kom ua kom muaj kev ntxhov siab hauv zos thaum txiav rau hauv cov ntaub so ntswg, ua tiav"micro- tawg"txiav es tsis yog compression thiab tearing, yog li txo qhov rub ntawm cov ntaub so ntswg ib puag ncig. Nyob rau tib lub sijhawm, cov duab geometric tshwj xeeb ntawm kev txiav ntug tuaj yeem tsim qhov sab hauv"suction"quab yuam thaum tig, pab kom ruaj khov ntes cov hom phiaj.
• Tsim cov kua Dynamics nti tshem tawm Grooves:Peb suav hais tias cov nti tshem tawm grooves ntawm cov hniav ua cov kua dej me me. Los ntawm kev suav cov kua dej dynamics simulation, peb optimize tus ntoo khaub lig-sectional puab, qhov tob, helical kaum sab xis, thiab nto tiav ntawm cov grooves. Thaum cov hniav tig ntawm kev kub ceev, cov grooves tuaj yeem tsim kom muaj qhov ruaj khov, axial-tsis zoo siab vortex. Cov vortex no tuaj yeem ua tau zoo li ib"tornado", nquag"noj"cov ntaub so ntswg txiav mus rau hauv qhov sib sib zog nqus ntawm qhov zawj thiab tshem tawm los ntawm lub hollow ncej, zoo tiv thaiv cov khib nyiab los ntawm accumulating thiab thaiv ntawm cov hniav lub taub hau qhov rais. Daim iav super- polished nto ntawm qhov zawj ntxiv txo cov dej tsis kam.
• Dynamic Balance thiab Vibration Reduction Design:Peb ua siab -ceev dynamic tshuav calibration rau txhua tus hniav tsim. Los ntawm kev faib khoom hnyav lossis tshem tawm cov khoom siv, peb xyuas kom meej tias qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm cov hniav zoo sib xws nrog kev sib hloov axis ntawm ntau kaum tawm txhiab tus kiv puag ncig ib feeb, tswj kev vibration amplitude mus rau qib micrometer. Qhov no tsis tsuas yog txhim kho kev ua haujlwm zoo (tshem tawm cov"ntse tes"kev hnov ​​​​qab), tab sis kuj tseem txo qis cov ntaub so ntswg kev puas tsuaj thiab kev qaug zog ntawm cov hniav sib txuas vim yog kev co.

Mechanism ntawm Action:

Lub luag haujlwm tseem ceeb ntawm nws txoj haujlwm yog kev hloov pauv hluav taws xob zoo thiab kev tswj xyuas cov kua dej. Lub optimized txiav ntug geometry converts lub rotational kinetic zog ntawm lub cev muaj zog mus rau shear quab yuam ntawm lub hom phiaj cov ntaub so ntswg nyob rau hauv lub feem ntau concentrated yam nrog tsawg zog poob, ua tiav ib"huv thiab ua tau zoo"txiav. Nyob rau tib lub sij hawm, lub rotating hniav nws tus kheej ua ib tug"centrifugal twj tso kua mis"thiab lub tshuab hluav taws xob ntawm Venturi nyhuv. Qhov zoo tshaj plaws nti tshem tawm grooves, thaum tig, nrog lawv cov duab tshwj xeeb coj cov ntaub so ntswg kua thiab airflow los ua ib tug siab -ceev, qis - siab vortex teb. Qhov chaw vortex no muaj ob qhov teebmeem: ib qho yog los tsim kom muaj zog"suction"thiab"kev thauj mus los"quab yuam rau ntawm cov khib nyiab tshiab, ua tiav kev tu lub qhov txhab tam sim; lwm tus yog tsim ib"kwv dej barrier"ntawm lub taub hau lub qhov rais, tsis tu ncua yaug tawm cov ntaub so ntswg tshiab thiab tswj kom pom tseeb ntawm qhov rais. Dynamic tshuav nyiaj li cas los xyuas kom meej tias tag nrho cov txheej txheem mechanical tshwm sim ntawm lub platform ruaj khov thiab tswj tau.

Kev Tshawb Fawb Txog Kev Ua Haujlwm:

Nyob rau hauv kev simulation cov ntaub so ntswg txiav, peb optimized tsim hniav, piv nrog cov tsoos hniav ntawm tib yam specification, txo lub sij hawm yuav tsum tau txiav tib yam kev ntxhib los mos thiab ntim ntawm simulated ntaub so ntswg los ntawm kwv yees li 25%, thiab txo lub lateral traction quab yuam ntawm lub simulated cov ntaub so ntswg thaum lub sij hawm txiav txheej txheem los ntawm 40%. Nyob rau hauv siab -kev yees duab ceev, cov nti tshem tawm kev ua haujlwm tau nce ntau dua 50%, thiab qhov tshwm sim clogging tau pib tshem tawm. Cov ntaub ntawv ntsuas kev vibration tau pom tias ntawm qhov ntsuas siab tshaj plaws kev sib hloov ceev, qhov kev vibration acceleration tus nqi ntawm cov hniav ntawm peb cov hniav yog 60% qis dua qhov nruab nrab ntawm kev lag luam. Cov kws kho mob tau tshaj tawm tias thaum siv cov hniav tsim tshiab, kev ua haujlwm ruaj khov, kev txiav ntau dua"hauv sync nrog tes", thiab hauv kev tuav cov ntaub so ntswg uas nplua nuj nyob hauv cov hlab ntsha, qhov pom tseeb ntawm qhov chaw phais mob tau khaws cia rau lub sijhawm ntev, txo tus naj npawb ntawm cov dej yaug thiab ua rau cov kev phais mob kom zoo dua.

Kev tshawb fawb thiab kev loj hlob Strategy thiab Philosophy:

Peb ntseeg tias:"Ib tug zoo hniav tsim yog kev sib raug zoo seev cev ntawm statics, dynamics thiab dej dynamics ntawm lub microscopic scale."Peb cov kev tshawb fawb thiab kev tsim kho lub tswv yim yog siv ntau -physics teb simulation cov cuab yeej los hloov cov kev cai kho mob tsis meej xws li'zoo siab', 'zoo txiav', thiab'tsis muaj clogging'mus rau qhov tseeb geometric tsis thiab ntsuas lub cev. Peb tsis tsuas yog tsim cov duab ntawm cov hniav, tab sis kuj yog'kev tawm mus'ntawm cov ntaub so ntswg. Peb tau cog lus tias yuav tsim txhua qhov kev txiav mus rau qhov ua tau zoo thiab tswj tau micro-system engineering.

Yav tom ntej Outlook:

Nyob rau hauv lub neej yav tom ntej, peb yuav txav mus rau"adaptive geometry" yogthiab"intelligent flow field control."Cov lus qhia kev tshawb fawb muaj xws li: txhim kho cov khoom siv ntse uas tuaj yeem hloov kho lub kaum sab xis raws li lub zog torque; tshawb fawb txog kev sib koom ua ke ntawm micro-sensors ntawm cov hniav txhawm rau saib xyuas kev txiav quab yuam, qhov kub thiab txias, thiab thaiv qhov xwm txheej ntawm lub sijhawm tiag tiag, thiab ua cov lus tawm tswv yim los ntawm kev kho cov kev sib hloov ceev lossis dej ntws; Tshawb nrhiav kev siv cov kua dej ntau dua xws li cov nyhuv cavitation los txhim kho kev ua haujlwm ntawm kev tshem tawm cov ntaub so ntswg. Peb lub hom phiaj yog ua kom lub phiaj xwm dav hlau ntse nrog"kev nkag siab ib puag ncig - kev txiav txim siab- ua - kev ua tiav"muaj peev xwm, ua rau kev phais kev phais uas tsis tau pom dua ua ntej, yooj yim, thiab nyab xeeb.
