Lekholong la bo17 le la bo18 la lilemo e ne e le nako ea bohlokoa ea tsoelo-pele ea thuto ea hydraulic.Khopolo ea phetisetso ea khatello ea hydrostatic, theory ea sejoale-joale ea hydrodynamic lubrication, matla a mokelikeli le likhopolo tse ling tse thehiloeng le tse holileng nakong ena li ralile motheo oa thuto ea sejoale-joale ea hydraulic.'Me ka lebaka la litlhoko tsa lits'ebetso tse sebetsang, li-accumulators tse ling tse bonolo li boetse li hlaha, tse kang accumulator ea boima bo nang le sejana se tletseng metsi e le mokoloko oa boima.
Karolong e qetellang ea Ntoa ea II ea Lefatše, mechine ea hydraulic e ile ea ratoa, 'me tšebeliso ea phetisetso ea hydraulic servo indastering ea ho etsa libetsa tsa sesole e ile ea nolofalletsa nts'etsopele ea theknoloji ea phetisetso le taolo ea haeteroliki.Tsoelo-pele ea thekenoloji ea taolo ea haeteroliki, thekenoloji ea ho tiisa thepa ea ho tiisa le thekenoloji ea taolo ea othomathike le eona e thehile motheo oa theory bakeng sa nts'etsopele ea theory ea hydraulic control.Ka mor'a ntoa, theknoloji e tsoetseng pele ka lebaka la litlhoko tsa sesole butle-butle e ile ea fetohela masimong a indasteri le a sechaba, 'me ea qala ho atleha.Ka mantsoe a mang, ho tloha nakong ena, lipatlisiso tsa theoretical mabapi le li-accumulators bakeng sa theory e butsoitseng ea taolo ea hydraulic le thekenoloji e sebetsang e fumane tlhokomelo butle-butle.Ho na le li-accumulators tse sebelisoang ka kakaretso, tse kang li-accumulators tsa selemo, li-accumulators tse seng li hōlile haholoanyane le tse ling tse bonolo tse bokellang khase.
Ho tloha lilemong tsa bo-1970, bafuputsi ba qalile ho ela hloko lipatlisiso tsa thuto ea motheo ea li-accumulators (tse kang liforomo tsa khetho ea parameter le mekhoa ea ho bala khafetsa, joalo-joalo), 'me ba tsoelapele ho e ntlafatsa le ho e ntlafatsa.Ho elella bofelong ba lilemo tsa bo-1970, nts'etsopele ea theknoloji ea ho boloka matla a likoloi e ile ea khothalletsa lipatlisiso tsa li-accumulators le theknoloji ea ho boloka matla a accumulator, 'me mosebetsi oa ho boloka matla oa li-accumulators tsamaisong ea hydraulic o ile oa qala ho hohela tlhokomelo.Lilemong tsa bo-1980, sebopeho, mofuta, sebopeho le ts'ebetso ea li-accumulators li ile tsa qala ho fapana, 'me nts'etsopele ea mefuta e sa tšoaneng ea li-accumulators e ile ea e-ba litaba tsa sehlooho tsa lipatlisiso.Lilemong tsa bo-1990, nts'etsopele ea software e ncha ea khomphutha, hardware le thekenoloji ea taolo e fane ka lisebelisoa tse tsoetseng pele tsa ho etsa lipatlisiso le mekhoa ea ho etsa lipatlisiso tsa litsamaiso tsa haeteroliki le likaroloana tse bohlale tsa haeteroliki, tse ileng tsa beha litlhoko tse ncha tsa lipatlisiso tsa li-accumulators.
Nts'etsopele ea theory le thekenoloji ea hydraulic ha e arohane le lipatlisiso le nts'etsopele ea likarolo tse ncha tsa haeteroliki.Hajoale, mosebetsi oa ho etsa lipatlisiso ka li-accumulators lapeng le kantle ho naha ka kakaretso o na le lintlha tse latelang.
① Ho ikamahanya le nts'etsopele ea lipatlisiso tse ncha tsa hydraulic system, lipatlisiso tse ling li entsoe mabapi le ts'ebeliso ea mahlale.Ka nts'etsopele ea litsamaiso tsa hydraulic ka tataiso ea khatello e phahameng, lebelo le phahameng, le ho nepahala ho phahameng, litsamaiso tse ngata tse khethehileng li ntse li tsoela pele ho hlaha.Litsamaiso tsena ka kakaretso li na le litlhoko tse phahameng bakeng sa karolo e itseng, 'me sepheo se ke ke sa finyelloa feela ka ho ntlafatsa likarolo tse ling, kahoo hoa hlokahala ho hlahisa accumulator e khethehileng e le mokhoa.Ka mohlala, bakeng sa ho monya pulsation.Shini-chi YOKOTA ea Japane e hlahisitse mofuta o mocha oa accumulator e sebetsang, e tsamaisoang ke lisebelisoa tse ngata tsa PED (Piezo-Electric Device), tse ka khonang ho felisa ka katleho pulsation e phahameng-frequency (500-1000Hz) e bakoang ke lisebelisoa tsa hydraulic.Mohlala o mong ke letoto la li-capsule accumulator tse ntlafalitsoeng ke Xing Keli le ba bang ba tsoang Univesithing ea Xi'an Jiaotong, e nang le phello e ntle ea ho monya ho pulsation ka makhetlo a 112-288Hz.'Me ha e bapisoa le li-accumulators tse tloaelehileng, bandwidth ea eona ea attenuation e pharalletse.
② Ho kopanya khopolo e teng ea accumulator le mekhoa e mecha ea tlhahlobo le thuto ea taolo, joalo-joalo, ho qapa ka mokhoa oa theory, ke hore, ho ipapisitse le khopolo e teng, ho sebelisa mekhoa le mekhoa e tsoetseng pele ea ho etsa lipatlisiso ho fumana liphetho tsa bohlokoa tsa thuto.Ka mohlala, Chen Zhaodi oa Harbin Institute of Technology le ba bang ba ile ba sebelisa khopolo ea bond graph ho hlahloba phello ea li-accumulators khatellong ea khatello ea tsamaiso ea lipeipi.Ba thehile mohlala o matla oa lipalo oa accumulator ka ho sebelisa thuto ea bond graph, ba paka phello ea khatello ea accumulator khatellong ea khatello, 'me ba beha khopolo ea bohlokoa mabapi le mosebetsi oa accumulator ho monya khatello ea maikutlo.Mokhoa ona o ka boela oa fetisetsoa ho tlhahlobo e matla ea lisebelisoa tse ling tsa hydraulic tse nang le li-accumulators.
③ Ho ipapisitsoe le khopolo e teng ea accumulator le hydraulic system theory, e kopantsoeng le moralo o mocha le software ea lipalo e le software e tšehetsang, software ea moralo o thusang oa potoloho le lipalo kapa tlhahlobo ea ntlafatsoa.Ka mohlala, Sharp EL512 calculator e qalileng ke Par.ker Hannifin Corp e ka thusa basebelisi ho khetha li-parameter tsa accumulator. Ho phaella moo, Wu Xiaoming le ba bang ba tsoang Univesithing ea Yanshan, motheong oa lipatlisiso tse lekaneng ka li-accumulators le likhopolo tsa bona, ba sebelisa khopolo ea "e kenyelelitsoeng". ” Sistimi ea litsebi ho nts'etsapele li-accumulators le software ea bona ea potoloho ka bohlale.Accumulator le software ea eona ea potoloho e thusitseng moralo o fumanoeng o ka thusa baetsi ba sistimi ho khetha accumulator e loketseng habonolo.Hona joale, ho ntse ho e-na le khaello ea mekhoa e sebetsang haholo bakeng sa tlhahlobo ea litšobotsi tsa li-accumulators, tse lebisang ka ho toba ho mekhahlelo e sa phethahalang ea li-accumulator, e sa hlakang. litšoaneleho tse matla, le kutloisiso e sa hlakang ea litšoaneleho tse joalo ka sebaka se sebetsang hantle sa li-accumulators.Sena se tlisa bothata bo boholo khethong ea accumulator, 'me ka tsela e sa tobang se lebisa liphosong tsa khetho.Ho phaella moo, tsamaiso ea khetho e ke ke ea e tseba ka nepo ho ea ka litšobotsi tse matla tsa potoloho ea hydraulic, tse kang khatello ea ho tlatsa naetrojene.Ka mantsoe a mang, bothata bo ts'oanang ba li-parameter tsa accumulator le tikoloho ea ts'ebeliso ha bo so rarolloe ka botlalo.Ka hona, nts'etsopele ea theknoloji e matla ea tlhahlobo ea ts'ebetso ea accumulator e na le boleng bo bongata bo sebetsang. Sebelisa theknoloji ea lisebelisoa tsa tlhahlobo ho teko ea accumulator.Sena se tla fana ka papali e felletseng ho litšoaneleho tse bonolo, tse potlakileng, tse sebetsang hantle le tse nepahetseng tsa theknoloji ea lisebelisoa tse fumanehang.'Me u leke ka nepo li-parameter tse matla tsa accumulator, e le hore sistimi e loketse litšobotsi tsa ts'ebetso le litlhoko tsa tšebeliso ea accumulator.Li-curve tsa ts'ebetso ea li-accumulator tse nang le litlhaloso tse fapaneng li ka fumanoa ka liteko tsa marang-rang le tsa papiso ea li-accumulators.
