Lub 17th thiab 18th centuries yog lub heyday ntawm txoj kev loj hlob ntawm hydraulic txoj kev xav.Lub hydrostatic siab kis txoj kev xav, niaj hnub hydrodynamic lubrication txoj kev xav, kua dynamics thiab lwm yam theories tsim thiab matured nyob rau hauv lub sij hawm no yeej nteg lub hauv paus rau niaj hnub hydraulic txoj kev xav.Thiab vim hais tias ntawm cov kev xav tau ntawm kev siv tswv yim, qee qhov yooj yim accumulators kuj tshwm sim, xws li ib qho hnyav accumulator nrog ib lub thawv ntim dej uas yog ib qho loj thaiv.
Nyob rau yav tas los ntawm Ntiaj Teb Tsov Rog II, hydraulic machinery tau txais kev pom zoo, thiab daim ntawv thov ntawm hydraulic servo kis tau tus mob nyob rau hauv cov tub rog riam phom tsim kev lag luam enabled txoj kev loj hlob ntawm hydraulic kis tau tus mob thiab tswj technology.Kev nce qib hauv hydraulic tswj thev naus laus zis, cov khoom siv sealing lubrication thev naus laus zis thiab kev tswj tsis siv neeg thev naus laus zis kuj tau tsim lub hauv paus theoretical rau kev txhim kho hydraulic tswj txoj kev xav.Tom qab ua tsov ua rog, thev naus laus zis tsim los ntawm kev xav tau tub rog maj mam tig mus rau kev lag luam thiab pej xeem, thiab pib vam meej.Uas yog hais tias, los ntawm lub sij hawm no, kev tshawb fawb theoretical ntawm accumulators rau paub tab hydraulic tswj txoj kev xav thiab cov tswv yim thev naus laus zis tau maj mam tau txais kev mloog.Muaj qee lub hom phiaj dav dav accumulators, xws li lub caij nplooj ntoos hlav accumulators, ntau qhov hnyav accumulators thiab qee cov roj accumulators yooj yim.
Txij li thaum xyoo 1970s, cov kws tshawb fawb tau pib ua tib zoo saib xyuas cov kev tshawb fawb ntawm cov kev xav ntawm cov accumulators (xws li parameter xaiv cov qauv thiab cov qauv kev suav zaus, thiab lwm yam), thiab txuas ntxiv txhim kho lawv.Thaum xyoo 1970s, txoj kev loj hlob ntawm lub tsheb txuag hluav taws xob tau txhawb kev tshawb fawb ntawm accumulators thiab accumulator zog-txuag technologies, thiab lub zog txuag kev ua haujlwm ntawm accumulators hauv hydraulic systems pib nyiam.Nyob rau xyoo 1980, cov qauv, hom, daim ntawv thiab kev ua haujlwm ntawm accumulators pib muaj ntau haiv neeg, thiab kev loj hlob ntawm ntau hom accumulators tau los ua cov ntsiab lus tseem ceeb ntawm kev tshawb fawb.Nyob rau xyoo 1990, kev txhim kho ntawm cov khoos phis tawj tshiab, kho vajtse thiab kev tswj hwm thev naus laus zis tau muab cov cuab yeej tshawb fawb qib siab thiab txhais tau tias rau kev tshawb fawb ntawm hydraulic systems thiab ntse hydraulic Cheebtsam, uas tso rau pem hauv ntej cov kev cai tshiab rau kev tshawb fawb ntawm accumulators.
Txoj kev loj hlob ntawm hydraulic txoj kev xav thiab thev naus laus zis yog sib cais los ntawm kev tshawb fawb thiab kev tsim cov khoom siv hydraulic tshiab.Tam sim no, kev tshawb fawb ua haujlwm ntawm accumulators hauv tsev thiab txawv teb chaws feem ntau muaj cov hauv qab no.
① Txhawm rau hloov mus rau txoj kev loj hlob ntawm kev tshawb fawb hydraulic tshiab, kev tshawb fawb ntxiv tau ua tiav ntawm daim ntawv thov thev naus laus zis.Nrog rau txoj kev loj hlob ntawm hydraulic systems nyob rau hauv cov kev taw qhia ntawm kev kub siab, kev kub ceev, thiab high precision, muaj ntau yam tshwj xeeb systems txuas ntxiv mus.Cov tshuab no feem ntau muaj cov kev xav tau siab rau qee yam, thiab lub hom phiaj tsis tuaj yeem ua tiav tsuas yog los ntawm kev txhim kho lwm yam khoom, yog li nws yog ib qho tsim nyog los tsim ib qho tshwj xeeb accumulator raws li ib tug txhais tau tias.Piv txwv li rau absorbing pulsation.Nyiv lub Shini-chi YOKOTA tau tsim ib hom tshiab ntawm active accumulator, uas yog tsav los ntawm ib tug multi-theem PED (Piezo-Electric Device) ntaus ntawv, uas yuav zoo tshem tawm high-frequency pulsation (500-1000Hz) tshwm sim los ntawm hydraulic Cheebtsam.Lwm qhov piv txwv yog cov tshuaj capsule accumulator tsim los ntawm Xing Keli thiab lwm tus los ntawm Xi'an Jiaotong University, uas muaj qhov nqus tau zoo ntawm lub pulsation nrog zaus ntawm 112-288Hz.Thiab piv nrog cov pa accumulators, nws attenuation bandwidth yog dav dua.
② Kev sib txuas cov kev xav uas twb muaj lawm nrog cov kev tshawb fawb tshiab thiab kev tswj xyuas, thiab lwm yam, los tsim kho theoretical, uas yog, raws li cov kev xav uas twb muaj lawm, txais yuav ntau txoj kev tshawb fawb thiab cov txheej txheem kom tau txais txiaj ntsig zoo dua.Piv txwv li, Chen Zhaodi los ntawm Harbin lub koom haum thev naus laus zis thiab lwm tus tau siv daim ntawv cog lus graph theory los tshuaj xyuas qhov cuam tshuam ntawm cov khoom ntim ntawm lub siab poob siab ntawm cov kav dej.Lawv tau tsim ib tug dynamic lej qauv ntawm lub accumulator los ntawm kev siv daim ntawv cog lus graph txoj kev xav, ua pov thawj cov nyhuv ntawm lub accumulator ntawm lub siab poob siab, thiab muab tso rau pem hauv ntej ib tug tseem ceeb txoj kev xav ntawm lub functionality ntawm lub accumulator kom nqus tau lub siab pulsation.Txoj kev no tseem tuaj yeem txuas ntxiv mus rau qhov kev soj ntsuam dynamic ntawm lwm cov tshuab hydraulic uas muaj cov khoom siv.
③ Raws li cov kev xav uas twb muaj lawm accumulator thiab hydraulic system txoj kev xav, ua ke nrog cov tshiab tsim thiab suav software raws li kev txhawb nqa software, software rau accumulator circuit auxiliary tsim thiab xam los yog kuaj yog tsim.Piv txwv li, lub tshuab xam zauv Sharp EL512 pib los ntawm Par.ker Hannifin Corp tuaj yeem pab cov neeg siv xaiv cov khoom sib xyaw ua ke. Tsis tas li ntawd, Wu Xiaoming thiab lwm tus los ntawm Yanshan University, raws li kev tshawb fawb txaus ntawm accumulators thiab lawv cov kev xav, siv txoj kev xav ntawm "embedded "cov kws tshaj lij tshuab kom txawj ntse tsim cov khoom siv hluav taws xob thiab lawv cov software circuit.Lub accumulator thiab nws cov Circuit Court pab tsim software yog li tau txais tuaj yeem pab cov neeg tsim qauv xaiv qhov tsim nyog accumulator tau yooj yim.Tam sim no, tseem tsis muaj txoj hauv kev zoo heev rau cov yam ntxwv ntawm cov accumulators, uas ncaj qha ua rau qhov tsis zoo ntawm cov accumulators, tsis meej. dynamic yam ntxwv, thiab kev nkag siab tsis meej ntawm cov cwj pwm xws li qhov chaw ua haujlwm zoo tshaj plaws ntawm cov khoom siv.Qhov no ua rau muaj teeb meem loj rau kev xaiv ntawm lub accumulator, thiab tsis ncaj qha ua rau kev xaiv yuam kev.Tsis tas li ntawd, qhov kev xaiv tsis tuaj yeem txiav txim siab nws raws li cov yam ntxwv ntawm cov hydraulic Circuit Court, xws li nitrogen filling siab.Qhov ntawd yog hais tias, qhov teeb meem txuam ntawm accumulator tsis thiab daim ntawv thov ib puag ncig tsis tau daws qhov teeb meem.Yog li ntawd, txoj kev loj hlob ntawm dynamic kev ua tau zoo xeem technology ntawm accumulator muaj zoo tswv yim tus nqi.Siv virtual instrument technology rau qhov kev xeem ntawm accumulator.Qhov no yuav muab kev ua si tag nrho rau qhov yooj yim, nrawm, ua haujlwm tau zoo thiab muaj tseeb ntawm cov cuab yeej siv tshuab virtual hauv kev tshawb pom.Thiab ntsuas qhov ua tau zoo ntawm cov khoom siv hluav taws xob tsis zoo ntawm lub accumulator, kom lub kaw lus tsim nyog rau cov yam ntxwv ntawm kev ua haujlwm thiab siv cov kev xav tau ntawm lub accumulator.Qhov kev ua tau zoo ntawm cov accumulators nrog cov kev qhia tshwj xeeb tuaj yeem tau txais los ntawm online thiab simulation kev sim ntawm accumulators.
