Muzana ramakore rechi 17 nerechi 18 rakanga riri zuva guru rekuvandudzwa kwe hydraulic theory.Iyo hydrostatic pressure transmission theory, yemazuva ano hydrodynamic lubrication theory, fluid dynamics uye dzimwe dzidziso dzakaumbwa uye dzakakura panguva ino dzakaisa hwaro hwechimanjemanje hydraulic theory.Uye nekuda kwezvinodiwa zvekushandisa zvinoshanda, mamwe akareruka accumulators anoonekwawo, senge uremu accumulator ine mudziyo uzere nemvura sechivharo chikuru.
Muchikamu chekupedzisira cheHondo Yenyika II, michina ye hydraulic yakafarirwa, uye kushandiswa kwehydraulic servo kutapurirana muindasitiri yekugadzira zvombo zvehondo kwakagonesa kuvandudzwa kweiyo hydraulic transmission uye control tekinoroji.Kufambira mberi mu hydraulic control tekinoroji, tekinoroji yekuisa chisimbiso tekinoroji uye otomatiki yekudzora tekinoroji yakaisawo hwaro hwe theoretical yekuvandudza hydraulic control theory.Mushure mehondo, tekinoroji yakagadziridzwa nekuda kwezvido zvemauto zvishoma nezvishoma yakatendeukira kuminda yeindasitiri neyevanhu, ndokutanga kubudirira.Kureva kuti, kubva panguva ino, iyo theoretical research yeaccumulators yeakura hydraulic control theory uye inoshanda tekinoroji yakagamuchira tarisiro zvishoma nezvishoma.Kune mamwe-akawanda-chinangwa accumulators, akadai sechirimo accumulators, akakura uremu accumulators uye mamwe akareruka gasi accumulators.
Kubva kuma1970, vaongorori vakatanga kutarisisa kutsvagurudzo padzidziso yekutanga yeaccumulators (senge parameter yekusarudza mafomula uye frequency calculation formulas, nezvimwewo), uye ramba uchiagadzira nekuvandudza iwo.Mukupera kwema1970, kuvandudza tekinoroji yekuchengetedza simba remotokari kwakasimudzira tsvakiridzo yeaccumulators uye accumulator ekuchengetedza simba tekinoroji, uye basa rekuchengetedza simba reanounganidza muma hydraulic system rakatanga kukwezva kutarisa.Mumakore ekuma1980, chimiro, rudzi, chimiro uye basa rezviunganidzi zvakatanga kusiyanisa, uye kuvandudzwa kwemhando dzakasiyana-siyana dzezviunganidzi kwakava chikuru chekutsvaga.Mumakore ekuma1990, kuvandudzwa kwekombiyuta itsva software, hardware uye tekinoroji yekudzora yakapa maturusi epamusoro ekutsvagisa uye nzira dzekutsvagisa hydraulic masisitimu uye nehungwaru hydraulic components, izvo zvinoisa mberi zvitsva zvinodiwa pakutsvagisa kweanounganidza.
Iko kuvandudzwa kweiyo hydraulic theory uye tekinoroji hazviparadzaniswe kubva mukutsvagisa uye kuvandudzwa kwezvinhu zvitsva zvehydraulic.Parizvino, basa rekutsvagisa pane accumulators kumba nekune dzimwe nyika kazhinji rine zvinotevera zvinhu.
① Kuenderana nekuvandudzwa kwetsvakiridzo ye hydraulic system, tsvakiridzo yakawanda yakaitwa pakushandisa tekinoroji.Nekuvandudzwa kwema hydraulic system munzira yekumanikidza kwakanyanya, kumhanya kwepamusoro, uye kurongeka kwakanyanya, akawanda akakosha masisitimu anoramba achionekwa.Aya masisitimu anowanzo ane zvakakwirira zvinodikanwa zvechimwe chinhu, uye chinangwa hachigone kuwanikwa nekuvandudza zvimwe zvikamu, saka zvinodikanwa kugadzira yakakosha accumulator senzira.Semuenzaniso wekutora pulsation.Shini-chi YOKOTA yeJapan yakagadzira rudzi rutsva rwekugadzirisa accumulator, iyo inotungamirirwa ne-multi-stage PED (Piezo-Electric Device) device, inogona kunyatsobvisa high-frequency pulsation (500-1000Hz) inokonzerwa ne hydraulic components.Mumwe muenzaniso ndeye yakatevedzana capsule accumulator yakagadziridzwa naXing Keli nevamwe kubva kuXi'an Jiaotong University, ine yakanaka yekunyudza mhedzisiro pakupuruzira ine frequency ye112-288Hz.Uye kana ichienzaniswa neyakajairwa accumulators, ayo attenuation bandwidth yakafara.
② Kubatanidza dzidziso yeaccumulator iripo nemaitiro matsva ekuongorora uye dzidziso yekudzora, zvichingodaro, kugadzira dzidziso, kureva, zvichibva pane dzidziso iripo, tora nzira dzepamusoro dzetsvakiridzo uye nzira dzekuwana akakosha edzidziso mhedzisiro.Semuyenzaniso, Chen Zhaodi anobva kuHarbin Institute of Technology nevamwe vakashandisa dzidziso yegirafu yechisungo kuongorora mabatiro anoita ma accumulators pakudzvinyirirwa kwepombi.Vakagadzira dhizaini yemasvomhu modhi yeaccumulator vachishandisa chisungo chegirafu dzidziso, vakaratidza kudzvanya kweiyo accumulator pakuvhunduka kwekumanikidzwa, uye vakaisa dzidziso yakakosha pakushanda kweaccumulator kuti itore kudzvanywa.Iyi nzira inogona zvakare kukwidziridzwa kune inosimba kuongororwa kwemamwe hydraulic masisitimu ane accumulators.
③ Zvichienderana neiyo iripo accumulator theory uye hydraulic system theory, yakasanganiswa neyekubuda dhizaini uye kuverenga software sekutsigira software, software yeaccumulator yedunhu yekubatsira dhizaini uye kuverenga kana kuyedzwa inogadzirwa.Semuenzaniso, Sharp EL512 calculator yakatangwa nePar.ker Hannifin Corp inogona kubatsira vashandisi kusarudza accumulator parameters. Uyezve, Wu Xiaoming nevamwe vanobva kuYunivhesiti yeYanshan, pamusana pekutsvakurudza kwakakwana pamusoro pekuunganidza uye dzidziso dzavo, vanoshandisa dzidziso ye "yakaiswa mukati. ” nyanzvi masisitimu ekugadzira zvine hungwaru ma accumulators uye yavo yedunhu software.Iyo accumulator uye dunhu rayo rinobatsira dhizaini software saka yakawanikwa inogona kubatsira vanogadzira masisitimu kuti vasarudze yakakodzera accumulator zviri nyore.Parizvino, kuchine kushaikwa kwenzira dzinoshanda kwazvo dzekuongororwa kwehunhu hwema accumulators, izvo zvinotungamira zvakananga kune isina kukwana parameter ye accumulators, isina kujeka. hunhu hune simba, uye kunzwisiswa kusina kujeka kwehunhu hwakadai seyakanyanya kushanda nzvimbo yeanounganidza.Izvi zvinounza kuoma kukuru pakusarudzwa kweaccumulator, uye zvisina kunanga zvinotungamirira kuzvikanganiso zvekusarudza.Mukuwedzera, iyo yekusarudza sisitimu haigone kunyatso tsanangura iyo zvinoenderana neakasimba maitiro eiyo hydraulic wedunhu, senge nitrogen yekuzadza kumanikidza.Kureva kuti, dambudziko rekufananidza reaccumulator paramita uye nharaunda yekushandisa harina kugadziriswa zvakanyanya.Naizvozvo, kuvandudzwa kwesimba rekuedza tekinoroji yeaccumulator ine hukuru hunoshanda kukosha.Shandisa virtual instrument tekinoroji kune bvunzo ye accumulator.Izvi zvinopa kutamba kwakazara kune yakapusa, inokurumidza, inoshanda uye yakaringana maitiro eiyo chaiyo chiridzwa tekinoroji mukuona.Uye kunyatso edza mashandiro ane simba maparamendi eiyo accumulator, kuitira kuti sisitimu ienderane nemaitiro ekuita uye kushandisa zvinodiwa zveaccumulator.Iwo ekuita macurves e accumulators ane akasiyana zvirevo anogona kuwanikwa kuburikidza ne-on-line uye simulation bvunzo dze accumulators.
Boka rekutanga revakapedza kudzidza vakanyanya mu hydraulics mushure mekunge bvunzo dzepakoreji yenyika dzatangazve

Mufananidzo kunobva: Yanda Hydraulics
Nekuvandudzwa kweiyo hydraulic system, izvo zvinodikanwa zveiyo system zviri kuwedzera nekukwira.Iyo yekutanga dzidziso uye chimiro cheiyo iripo accumulator haichakwanise kusangana nekuvandudzwa kwekutsvagisa pane iyo hydraulic system uye hydraulic components.Chikonzero chikuru ndechekuti mazhinji edzidziso dzekutanga dziripo dzekuunganidza dzakavambwa muma1970 nema1980s, uye dzakawanikwa kuburikidza nekupfupisa ruzivo.Naizvozvo, mazhinji edzidziso idzi ane empirical, haana akamisikidzwa kana kubatana, uye anogona chete kutamba ekutanga kutungamira basa mukugadzira sisitimu.Iko kushandiswa chaiko kunoenderana nekuenderera mberi kwekugadzirisa uye kusarudzwa kwevashandi.Uyezve, chimiro cheiyo accumulator iripo inosarudza kuti mushure mekuiswa pahurongwa, iyo pachayo paramita haigone kuchinjwa zvinoenderana nezvinodiwa nehurongwa kuti isangane nezvinodiwa zvakasiyana zvehurongwa.Izvi zvakaunza zvipingamupinyi pakudzidza kwemahydraulic system uye mashandisirwo ehydraulic masisitimu mukuita engineering.
