KaviriPneumatic CylinderSarudzo Yekutungamira: Matanho Mashanu Akakosha kubva kuTheory kusvika Kudzidzira
Kusarudzwa kwemaviri-Pneumatic cylinder Pneumatic cylinders ipurojekiti yakarongeka uye haisi nyaya yakapusa ye "kusarudza Pneumatic cylinder diameter based on thrust". Sarudzo chaiyo inogona kuita kuti chishandiso chishande chakareba-chinyatsoshanda, nepo sarudzo isiriyo inogona kutungamira mukurasikirwa kwechokwadi, kukuvadzwa kwePneumatic cylinder, kana kusamira kwekugadzira. Chinyorwa chino chinokutungamirira nenzira yakajeka "-nhanho{4}}nhanho" dzekusarudza nesainzi kaviri-pneumatic cylinder.
Danho 1: Verengai inodiwa uye tanga waona iyo Pneumatic cylinder bore.
Ichi ndicho chikonzero chekusarudza. Iwe unofanirwa kutanga waverenga theoretical thrust inodiwa kutyaira mutoro.
Verenga iyo theoretical thrust (F):
F=(mutoro mukuru m × kukwidziridza a) + Frictional force f + simba rekunze F_external
(Cherechedza: Kana mafambiro ari yunifomu kana kumhanya kwakadzikira, izwi rekumhanyisa rinogona kuregererwa.)
Sarudza huwandu hwekutakura (η):
Mamiriro akajairwa (η Zvishoma pane kana kuenzana ne50%):
Aya ndiwo mamiriro anonyanya kushandiswa, achipa muganho wakakwana wehupenyu uye kugadzikana kwePneumatic cylinder.
Yakaderera-kumhanya kana kufamba kwakafanana (η Zvishoma pane kana kuenzana ne70%): Kana Silinda yePneumatic ichinonoka zvikuru (<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.
Verenga iyo theoretical kubuda simba rePneumatic cylinder uye dzosera kumashure kuverenga Pneumatic cylinder bore:
The theoretical output force of the double-Pneumatic cylinder f_Pneumatic cylinder=P ×A ×2 (apo A ari muchinjiko-chikamu chenzvimbo yeimwe Pneumatic cylinder)
Inodiwa Pneumatic silinda yekubuda simba F_ inodiwa=F dzidziso / η
Naizvozvo, inogona kuwanikwa kuti A=F_ inodiwa/(2 ×P), uye ipapo iyo shoma Pneumatic humburumbira dhayamita D inogona kuverengerwa.
Semuenzaniso: Kusundirwa kunodiwa ndeye 300N, kushanda nesimba ndeye 0.5MPa, uye chiyero chemutoro chinotorwa se0.5.
F_ inodiwa=300N / 0.5=600N
A=600N/(2 ×5 bar ×10) ≈60 mm² (Cherechedza: 1MPa=10bha≈10N/mm²)
Kana D=2 ×sqrt(60/π) ≈8.74mm, saka kanenge silinda yePneumatic ine dhayamita yakajairwa ye10mm inofanira kusarudzwa.
Danho rechipiri: Tarisa lateral mutoro uye nguva yekukotama
Ichi ndicho chinongedzo chepakati pakusarudzwa kwekaviri-Pneumatic cylinder Pneumatic cylinder, iyo inokanganisa zvakananga kutungamira uye hupenyu hwesevhisi. Kunyange zvazvo silinda -yepneumatic cylinder ichikwanisa kumira kune imwe lateral load, haifanire kudarika kukosha kwayo kunobvumirwa.
Nzira: Kubva paPneumatic cylinder yakakuberekera iwe yawakasarudza pakutanga uye sitiroko chaiyo, tarisa kune "Maximum concentrated load" chati yemuenzaniso wePneumatic cylinder (sezvinoratidzwa mumufananidzo wekutanga 5.4-26a).
Iyo chaiyo lateral mutoro iyo Pneumatic cylinder inotakura panguva yekushanda inofanira kuva shoma pane inobvumirwa kukosha kweiyo inopindirana sitiroko sezvakaratidzwa muchati. Kana muganho ukapfuudzwa, hombe Pneumatic humburumbira dhayamita kana yakasimba kutungamira fomu (senge gwara tsvimbo Pneumatic cylinder) inofanira kusarudzwa.
Nhanho 3: Simbisa iyo kinetic simba uye sarudza iyo buffer mhando
Iyo piston yePneumatic cylinder ine kinetic simba pakupera kwayo sitiroko. Kana iyo kinetic simba yakakura kwazvo, inokonzeresa kukanganisa, kudedera, uye kukuvara.
Verenga kinetic simba (E_k):
E_k = 1/2 ×m ×v²
(m inomiririra huremu hwese, uye v inomiririra iyo yakanyanya kukanganisa velocity)
Verification: Enzanisa yakaverengerwa kinetic simba ne "inobvumirwa kinetic simba" kukosha muPneumatic cylinder sample (sezvinoratidzwa muFigure 5.4-26b yezvinyorwa zvepakutanga).
Sarudzo
Kana E_k Kana E_k yakakura, modhi ine hydraulic buffer (yakadai seCXSL series) inofanira kusarudzwa, sezvo kukwanisa kwayo kutora simba rekinetic iri 2 kusvika ku3 nguva yepneumatic buffer. Nhanho 4: Funga nezvekumisikidza kumira uye mutoro wakawedzerwa Iyo yekumisikidza nzira (yakatwasuka / yakatwasuka) uye overhang (l) yemutoro inoburitsa dzimwe nguva dzekupidigura, izvo zvinokanganisa zvakanyanya hupenyu hwebasa uye kusarudzwa kwePneumatic cylinder. Sezvinoratidzwa muMufananidzo 5.4-27a, mutoro wakawedzerwa m uchaita chinguva M=m × g × l pamwe nehurefu l. Method: Izvo zvinodikanwa kutaura kune yakatsaurirwa dhiyagiramu yekusarudza yakapihwa nemugadziri (sezvinoratidzwa muMufananidzo 5.4-27b wezvinyorwa zvepakutanga) zvichibva pane yekumisikidza fomu, sitiroko, kumhanya, overhang l, uye load mass m. Mhedziso: Iyi chati ichapa zvakananga yakakurudzirwa shoma Pneumatic cylinder bore pasi pemamiriro ekushanda. Semuyenzaniso, kana yakaiswa yakatambarara, ine sipidhi ye400mm/s, sitiroko ye30mm, l=40mm, uye m=0.2kg, chati inokurudzira kusarudza CXSW25 (Pneumatic cylinder bore 25mm) pane modhi diki. Danho rechishanu: Simbisa nhevedzano uye mamwe mabasa Chekupedzisira, sarudza yakatarwa nhevedzano uye sarudzo zvichibva pane zvambotaurwa: CXS: Basic type, cushion, kana air cushion. CXSL: Yakashongedzwa nehydraulic buffer, ine simba rakasimba rekutora simba rekinetic uye inokodzera kushandiswa kwepakati nepamusoro-kumhanya. CXSW: Kaviri tsvimbo mhando, yakawanda symmetrical chimiro, nani kuomarara. Basa rekuwedzera: Zvakakosha here kuve nemhete yemagineti (yekuisa magineti switch kuti uone chinzvimbo)? Zvakakosha here kuisa zvishongedzo (zvakadai setsoka, flanges, nezvimwewo)? 3333 Kaviri Pneumatic silinda 12-CXSL32-75-Y69BZ Iyi modhi ndiyo yakajairika mhedzisiro yekutevera iri pamusoro sarudzo maitiro: Pneumatic humburumbira dhayamita 32mm: Inopa simba rakakwana uye lateral mutoro kuramba, kusangana nezvinodiwa zvepakati-zvikumbiro zvekutakura. CXSL dzakatevedzana: Yakavakwa-mu hydraulic buffer, iyo inokwanisa kunyatso tora mhedzisiro panopera sitiroko, ichibvumira kukurumidza kushanda kwepamusoro, kushanda zvakanaka, uye hupenyu hurefu hwesevhisi. Stroke 75mm: Iyi inowira mukati meiyo inowanzo shandiswa sitiroko renji uye inokodzera kwakawanda kubata nekunhonga maoparesheni. Yakakwirira-kutungamira kwakanyatsojeka: Iyo mbiri yepiston rod chimiro inopa yepamusoro yekukotama nguva kuramba kana ichienzaniswa neakajairwa Pneumatic cylinders, kuve nechokwadi kuti hapana kutenderera panguva yekushanda uye kunyatsomira. Yakatetepa uye yakamanikana: Inochengetedza nzvimbo yekuisa uye inokodzera zvakanyanya-kumisikidza zvimiro mumidziyo yemagetsi. Mhedziso: Kana, mushure mekuverenga kuburikidza ne-nhanho dzenhanho dziri pamusoro, ukaona kuti unoda silinda yakatetepa yePneumatic ine dhayamita inosvika 32mm, inoda kubhura kwakanaka uye nepamusoro-kutungamirirwa nemazvo, ipapo 12-CXSL32-75-Y69BZ hapana mubvunzo kuti isarudzo yakavimbika.
