KabiniI-Pneumatic CylinderIsikhokelo sokuKhetha: Amanyathelo amahlanu aPhambili ukusuka kwiThiyori ukuya kwiQeniso
Ukukhetha kabini-Isilinda soMphunga wePneumatic yiprojekthi ecwangcisiweyo kwaye ayingomcimbi olula "wokukhetha i-Pneumatic cylinder diameter ngokusekelwe kwithrust". Ukukhetha okuchanekileyo kunokuqinisekisa ixesha elide{2}}elizinzileyo kunye nokusebenza okuchanekileyo kwesixhobo, ngelixa ukhetho olungachanekanga lunokukhokelela ekulahlekeni kokuchaneka, ukonakala kwe-Pneumatic cylinder, okanye ukwehla kwemveliso. Eli nqaku liza kukukhokela ngendlela ecacileyo "-entlanu{4}}yokukhetha ngokwenzululwazi umbhobho ophindwe kabini-womoya.
Inyathelo 1: Bala ukutyhala okufunekayo kwaye uqale umisele iPneumatic cylinder bore.
Esi sisiseko sokhetho. Kufuneka uqale ubale i-thrust yethiyori efunekayo ukuqhuba umthwalo.
Bala i-thrust yethiyori (F):
F=(ubunzima bomthwalo m × ukukhawuleza a) + Ifrictional force f + yangaphandle amandla F_ngaphandle
(Qaphela: Ukuba intshukumo ifana okanye isantya siphantsi kakhulu, ixesha lokukhawulezisa linokungahoywa.)
Khetha umyinge womthwalo (η):
Imeko esemgangathweni (η Ngaphantsi okanye ilingana nama-50%):
Le yeyona meko isetyenziswa ngokuqhelekileyo, ukubonelela ngomda owaneleyo wobomi kunye nokuzinza kwe-Pneumatic cylinder.
Phantsi-isantya okanye intshukumo efanayo (η Ngaphantsi okanye ilingana no 70%): Ukuba isantya se-Pneumatic cylinder sicotha kakhulu (<100 mm/s) or it is static pressure maintenance, the load rate can be appropriately increased to select a smaller Pneumatic cylinder diameter, but caution should be exercised.
Bala amandla emveliso yethiyori yesilinda ye-Pneumatic kwaye ujike ubale i-Pneumatic cylinder bore:
Amandla emveliso yethiyori ephindwe kabini-Isilinda ye-Pneumatic f_Pneumatic cylinder=P ×A ×2 (apho u-A engumnqamlezo{4}}indawo yecandelo lombhobho omnye we-Pneumatic)
Amandla emveliso yePneumatic cylinder F_ efunekayo=F ithiyori / η
Ngoko ke, kunokufumaneka ukuba i-A=F_ efunekayo/(2 ×P), kwaye ke ubuncinci be-Pneumatic cylinder diameter D ingabalwa.
Umzekelo: I-thrust efunekayo yi-300N, uxinzelelo lokusebenza yi-0.5MPa, kwaye izinga lomthwalo lithathwa njenge-0.5.
F_ iyafuneka=300N / 0.5=600N
A=600N/(2 ×5 ibha ×10) ≈60 mm² (Qaphela: 1MPa=10ibar≈10N/mm²)
Ukuba i-D=2 ×sqrt (60/π) ≈8.74mm, ngoko ke ubuncinane i-cylinder ye-Pneumatic enomlinganiselo oqhelekileyo we-10mm kufuneka ikhethwe.
Inyathelo lesi-2: Jonga umthwalo osecaleni kunye nomzuzu wokugoba
Eli likhonkco eliphambili ekukhethweni kwe-double{0}}Isilinda ye-Pneumatic Pneumatic cylinders, echaphazela ngokuthe ngqo ukuchaneka kwesikhokelo kunye nobomi benkonzo. Nangona i-double-i-pneumatic cylinder inokumelana nomthwalo othile osecaleni, kufuneka ingagqithi kwixabiso layo elivumelekileyo.
Indlela: Ngokusekelwe kwi-cylinder ye-Pneumatic cylinder oyikhethileyo ekuqaleni kunye ne-stroke yangempela, bhekisa kwitshathi ethi "Umthwalo ophezulu ogxininisiweyo" wale modeli ye-cylinder ye-Pneumatic (njengoko kuboniswe kumfanekiso wokuqala 5.4-26a).
Umthwalo wangempela osecaleni othwala i-Pneumatic cylinder ngexesha lokusebenza kufuneka ube ngaphantsi kwexabiso elivumelekileyo lokubetha okuhambelanayo njengoko kuboniswe kwitshathi. Ukuba umda ugqithisiwe, kufuneka kukhethwe i-cylinder enkulu ye-Pneumatic cylinder okanye ifom ekhokelayo eyomeleleyo (efana nentonga yesikhokelo sombhobho we-pneumatic).
Inyathelo 3: Qinisekisa amandla e-kinetic kwaye ukhethe uhlobo lwe-buffer
I-piston ye-Pneumatic cylinder inamandla e-kinetic ekupheleni kokubetha kwayo. Ukuba amandla e-kinetic makhulu kakhulu, aya kubangela impembelelo, ukungcangcazela, kunye nomonakalo.
Bala amandla ekinetic (E_k):
E_k = 1/2 ×m ×v²
(m imele ubunzima bomthwalo bubonke, kwaye v imele isantya esiphezulu sempembelelo)
Ukuqinisekiswa: Thelekisa amandla e-kinetic ababalwayo kunye nexabiso "elivumelekileyo lamandla e-kinetic" kwisampuli ye-Pneumatic cylinder (njengoko kuboniswe kuMzobo 5.4-26b wesicatshulwa sokuqala).
Isigqibo
Ukuba E_k < amandla avumelekileyo ekinetic odidi olusemgangathweni, Khetha uhlobo olusisiseko olunesithinteli se-cushion okanye isithinteli segesi esilungelelanisiweyo.
Ukuba i-E_k inkulu, imodeli ene-hydraulic buffer (efana nochungechunge lwe-CXSL) kufuneka ikhethwe, njengoko amandla ayo okuthatha amandla e-kinetic yi-2 ukuya ku-3 amaxesha e-pneumatic buffer.
Inyathelo lesi-4: Qwalasela ukuma kofakelo kunye nomthwalo owandisiweyo
Indlela yokufakela (i-horizontal / vertical) kunye ne-overhang (l) yomthwalo iya kuvelisa ixesha elongezelelweyo lokuguqulwa, elichaphazela kakhulu ubomi benkonzo kunye nokukhethwa kwe-cylinder ye-Pneumatic.
Njengoko kubonisiwe kuMfanekiso 5.4-27a, umthwalo owandisiweyo m uya kuvelisa umzuzwana M=m × g × l ngobude l.
Indlela: Kuyimfuneko ukubhekisela kumzobo okhethiweyo wokukhetha onikezelwe ngumenzi (njengoko kuboniswe kuMzobo 5.4-27b wombhalo wokuqala) ngokusekelwe kwifom yokufakela, i-stroke, isantya, i-overhang l, kunye nomthwalo wobunzima m.
Isiphelo: Le tshati iya kubonelela ngokuthe ngqo ubuncinci obucetyisiweyo bePneumatic cylinder bore phantsi kweemeko ezithile zokusebenza. Umzekelo, xa ifakwe ngokuthe tye, ngesantya se-400mm/s, i-stroke ye-30mm, l=40mm, kunye ne-m{4}}kg, itshati icebisa ukuba ukhethe i-CXSW25 (i-Pneumatic cylinder bore 25mm) endaweni yemodeli encinci.
Inyathelo 5: Qinisekisa uthotho kunye nemisebenzi eyongezelelweyo
Okokugqibela, khetha uluhlu oluthile kunye neenketho ezisekelwe kwiziphumo ezikhankanywe ngasentla:
CXS: Uhlobo olusisiseko, umqamelo, okanye umqamelo womoya.
I-CXSL: Ixhotyiswe nge-hydraulic buffer, inamandla amakhulu okufunxa amandla e-kinetic kwaye ifanele usetyenziso oluphakathi kunye-nesantya esiphezulu.
I-CXSW: Uhlobo lwentonga ephindwe kabini, ulwakhiwo olulinganayo ngakumbi, ukuqina okungcono.
Umsebenzi owongezelelweyo: Ngaba kuyimfuneko ukuba nendandatho yamagnetic (yokufakela ukutshintshwa kwamagnetic ukuze kubonwe indawo)? Ngaba kuyimfuneko ukufaka izixhobo (ezifana neenyawo, iiflange, njl.)?
