Zaka za zana la 17 ndi 18 zinali chiyambi cha chitukuko cha chiphunzitso cha hydraulic.Chiphunzitso cha hydrostatic pressure transmission, chiphunzitso chamakono cha hydrodynamic lubrication, mphamvu zamadzimadzi ndi malingaliro ena omwe adapangidwa ndikukhwima panthawiyi adayala maziko a chiphunzitso chamakono cha hydraulic.Ndipo chifukwa cha zofunikira zogwiritsira ntchito, zosonkhanitsa zosavuta zimawonekeranso, monga chowonjezera cholemera chokhala ndi chidebe chodzaza madzi ngati chipika chachikulu.
Chakumapeto kwa Nkhondo Yachiwiri Yadziko Lonse, makina opangira ma hydraulic adakondedwa, ndipo kugwiritsa ntchito ma hydraulic servo transmission mumakampani opanga zida zankhondo kunapangitsa kuti pakhale ukadaulo wa hydraulic transmission and control.Kupita patsogolo kwaukadaulo waukadaulo wama hydraulic control, ukadaulo wosindikizira mafuta ndi ukadaulo wowongolera wodziwikiratu wayalanso maziko aukadaulo pakupanga chiphunzitso cha hydraulic control.Nkhondo itatha, teknoloji inayamba chifukwa cha zosowa zankhondo pang'onopang'ono inatembenukira ku minda ya mafakitale ndi ya anthu wamba, ndipo inayamba kukula.Ndiko kunena kuti, kuyambira nthawi imeneyi, kafukufuku wongopeka pa ma accumulators a chiphunzitso chowongolera ma hydraulic control ndi ukadaulo wothandiza walandira chidwi pang'onopang'ono.Pali zinthu zina zolimbikitsira ntchito zosiyanasiyana, monga zolimbikitsira masika, zowonjezeretsa zolemera zokhwima kwambiri ndi zowunjikira gasi zosavuta.
Kuyambira m'ma 1970, ofufuza ayamba kulabadira kafukufuku pa chiphunzitso choyambirira cha accumulators (monga mafotokozedwe osankhidwa a magawo ndi mawerengedwe afupipafupi, ndi zina), ndikupitiliza kukulitsa ndikusintha.Chakumapeto kwa zaka za m'ma 1970, chitukuko cha teknoloji yopulumutsa mphamvu yamagalimoto chinalimbikitsa kufufuza kwa ma accumulators ndi accumulator mphamvu zopulumutsa mphamvu, ndipo ntchito yopulumutsa mphamvu ya accumulators mu machitidwe a hydraulic inayamba kukopa chidwi.M'zaka za m'ma 1980, mapangidwe, mtundu, mawonekedwe ndi ntchito za accumulators zinayamba kusiyanasiyana, ndipo chitukuko cha mitundu yosiyanasiyana ya accumulators chinakhala nkhani yaikulu yofufuza.M'zaka za m'ma 1990, kupanga mapulogalamu atsopano apakompyuta, hardware ndi luso lamakono linapereka zipangizo zamakono zofufuzira ndi njira zofufuzira machitidwe a hydraulic ndi zigawo zanzeru zama hydraulic, zomwe zimayika patsogolo zofunikira zatsopano pa kafukufuku wa accumulators.
Kukula kwa chiphunzitso cha hydraulic ndiukadaulo sikungasiyanitsidwe ndi kafukufuku ndi chitukuko cha zida zatsopano zama hydraulic.Pakalipano, ntchito yofufuza pa accumulators kunyumba ndi kunja kawirikawiri ili ndi mbali zotsatirazi.
① Kuti agwirizane ndi chitukuko cha kafukufuku watsopano wa hydraulic system, kafukufuku wambiri wachitika pakugwiritsa ntchito ukadaulo.Ndi chitukuko cha machitidwe a hydraulic motsatira kuthamanga kwambiri, kuthamanga kwambiri, ndi kulondola kwambiri, machitidwe ambiri apadera akupitiriza kuonekera.Machitidwewa nthawi zambiri amakhala ndi zofunikira kwambiri pazinthu zina, ndipo cholinga sichingakwaniritsidwe mwa kukonza zigawo zina, choncho m'pofunika kupanga accumulator yapadera ngati njira.Mwachitsanzo kwa kuyamwa pulsation.Japan Shini-chi YOKOTA yapanga mtundu watsopano wa accumulator yogwira ntchito, yomwe imayendetsedwa ndi PED (Piezo-Electric Device) yamitundu yambiri, yomwe imatha kuthetsa kuthamanga kwapamwamba kwambiri (500-1000Hz) chifukwa cha zigawo za hydraulic.Chitsanzo china ndi kapisozi kapisozi accumulator opangidwa ndi Xing Keli ndi ena ochokera ku Xi'an Jiaotong University, amene ali ndi zotsatira zabwino mayamwidwe pa pulsation ndi pafupipafupi 112-288Hz.Ndipo poyerekeza ndi ma accumulators wamba, bandwidth yake yocheperako ndiyokulirapo.
② Kuphatikiza chiphunzitso cha accumulator chomwe chilipo ndi njira zatsopano zowunikira ndi chiphunzitso chowongolera, ndi zina zotero, kuti apange zatsopano, ndiye kuti, kutengera chiphunzitso chomwe chilipo, tsatirani njira zofufuzira zapamwamba ndi njira zopezera zotsatira zaukadaulo zamtengo wapatali.Mwachitsanzo, Chen Zhaodi wochokera ku Harbin Institute of Technology ndi ena adagwiritsa ntchito chiphunzitso cha ma bond graph kuti aunike momwe ma accumulators amakhudzira kugwedezeka kwa mapaipi.Iwo anakhazikitsa chitsanzo champhamvu cha masamu a accumulator pogwiritsa ntchito chiphunzitso cha graph ya bond, kutsimikizira kuponderezedwa kwa accumulator pa kugwedeza kwamphamvu, ndikuyika patsogolo chiphunzitso chamtengo wapatali pa ntchito ya accumulator kuti itenge kuthamanga kwa kuthamanga.Njirayi imatha kukulitsidwanso pakuwunika kwamphamvu kwa machitidwe ena a hydraulic okhala ndi ma accumulators.
③ Kutengera chiphunzitso cha accumulator chomwe chilipo komanso chiphunzitso cha hydraulic system, chophatikizidwa ndi mapangidwe atsopano ndi mapulogalamu owerengera ngati pulogalamu yothandizira, pulogalamu ya accumulator dera lothandizira kapangidwe ndikuwerengera kapena kuyesa imapangidwa.Mwachitsanzo, Sharp EL512 calculator yomwe inayambitsidwa ndi Par.ker Hannifin Corp ingathandize ogwiritsa ntchito kusankha magawo a accumulator.Kuonjezera apo, Wu Xiaoming ndi ena ochokera ku yunivesite ya Yanshan, pamaziko a kafukufuku wokwanira pa accumulators ndi malingaliro awo, amagwiritsa ntchito chiphunzitso cha "ophatikizidwa. ” Katswiri wamakina kuti apange mwanzeru ma accumulators ndi mapulogalamu awo ozungulira.The accumulator ndi dera anathandiza mapangidwe mapulogalamu kotero anapezedwa angathandize okonza dongosolo kusankha accumulator oyenera mosavuta. mawonekedwe osunthika, komanso kumvetsetsa kosamveka bwino kwamakhalidwe monga malo abwino kwambiri ogwirira ntchito a accumulators.Izi zimabweretsa vuto lalikulu pakusankha kosungirako, ndipo mosalunjika kumabweretsa zolakwika zosankhidwa.Kuphatikiza apo, makina osankhidwa sangathe kudziwa molondola malinga ndi mawonekedwe amphamvu a hydraulic circuit, monga kuthamanga kwa nayitrogeni.Ndiko kunena kuti, vuto lofananira la magawo a accumulator ndi malo ogwiritsira ntchito silinathetsedwa kwenikweni.Choncho, chitukuko cha ukadaulo woyezetsa magwiridwe antchito a accumulator ali ndi phindu lalikulu.Ikani ukadaulo wa zida zoyeserera poyesa accumulator.Izi zidzapereka kusewera kwathunthu ku zosavuta, zachangu, zogwira mtima komanso zolondola zaukadaulo wa zida zozindikirika.Ndipo yesani molondola magawo amphamvu a accumulator, kuti dongosololi likhale loyenera machitidwe ogwirira ntchito ndikugwiritsa ntchito zofunikira za accumulator.Ma curve a ma accumulators okhala ndi mawonekedwe osiyanasiyana amatha kupezeka kudzera pa intaneti komanso kuyesa kuyesa kwa ma accumulators.
Gulu loyamba la omaliza maphunziro a hydraulics pambuyo pa mayeso olowera ku koleji yadziko lonse adayambanso

Ndi chitukuko cha ma hydraulic system, zofunikira za dongosololi zikuchulukirachulukira.Lingaliro loyambira ndi kapangidwe ka accumulator yomwe ilipo sikungathenso kukumana ndi chitukuko cha kafukufuku wama hydraulic system ndi hydraulic components.Chifukwa chachikulu ndikuti malingaliro ambiri omwe alipo a accumulators adakhazikitsidwa m'ma 1970 ndi 1980s, ndipo adapezedwa kudzera muchidule cha zochitika.Chifukwa chake, ambiri mwa malingalirowa ndi amphamvu, osakhazikika kapena ogwirizana, ndipo amatha kungotenga gawo lotsogola pamapangidwe adongosolo.Kugwiritsa ntchito kwenikweni kumadalira kusokoneza kosalekeza ndi kusankha kwa ogwira ntchito.Komanso, mawonekedwe a accumulator omwe alipo amatsimikizira kuti atayikidwa pa dongosolo, magawo akewo sangathe kusinthidwa malinga ndi zofunikira za dongosolo kuti akwaniritse zosowa zosiyanasiyana za dongosolo.Izi zabweretsa zopinga pakuphunzira kwa ma hydraulic systems ndikugwiritsa ntchito ma hydraulic systems mu engineering practice.
