1, Mapangidwe a pre-deformation ndiye fungulo

Ponena za nkhungu ya pulasitiki yamagalimoto & tanki yamadzi, kuwongolera kwa mapangidwe ndi kupanga kumakhala kovuta kwambiri kuposa mtundu wamba, popeza mbali zamtunduwu nthawi zambiri zimawumbidwa ndi zinthu PA6 (PA66) + GF (30-35%), ndipo izi mtundu wa zinthu n'zosavuta kupeza mapindikidwe pa ndondomeko akamaumba, ndi lolingana mankhwala kukula n'zosavuta kukhala kunja kulolerana. Chifukwa chake, podziwa kusinthika kwake pafupipafupi, ndiye kuti kupanga mapangidwe asanachitike kutengera zomwe zachitika komanso kusanthula kwa CAE kumapangitsa kuti mapangidwe apangidwe akhale chinsinsi chakuchita bwino kwa nkhungu.

Gulu la Enuo mold lili ndi zaka zopitilira 10 pakupanga nkhungu, ndipo latumikira Valeo, Mahle-behr, Delphi ndi makasitomala ena otchuka padziko lonse lapansi. Apa tikuwonetsa mwachidule zomwe takumana nazo pakupanga nkhungu ya auto air & water tank. Zowonadi, makampani osiyanasiyana ali ndi machitidwe osiyanasiyana, ngati owerenga okondedwa ali ndi malingaliro osiyanasiyana, amalandilidwanso mwachikondi kulankhula nafe.

2, Kusanthula magawo azithunzi, fotokozani madera ofunikira a chinthucho ndi kukula kwake

Kuti mumvetsetse madera ofunikira a chinthucho ndi makulidwe ofunikira omwe amagwirizana nthawi zonse ndi sitepe yoyamba pomwe zojambula zamakasitomala zidafika, ndiye kuti samalani kwambiri pazifukwa zomwezo, monga "End surface" ("End surface" idafunikira kwambiri kuwongoka, kusalala. ndi kulolerana kukula kwa mawonekedwe, ndi mbali zina za gawo lazogulitsa zimatsatira kusintha kwawo), "dera la Tube orifice" (gawo la "chubu orifice" ndilofunikanso kwambiri, nthawi zambiri kuyika, kulekerera kwa cylindrical ndi dimensional kumafunika) ndi mankhwala " Nthiti za Bwana” ndi “U-mawonekedwe” ndi zina zotero, zikuwonetsedwa pansipa:

Kwa nkhungu yatsopano, konzekerani kusinthika kwa chinthucho (kuchita "chipukuta misozi" kumbali ina ya kusinthika koyerekeza pasadakhale malinga ndi zomwe zachitika komanso kusanthula kwa CAE, lingalirani kuti ziwongolere pambuyo pa kupindika kwenikweni). Pambuyo poyeserera nkhungu, kuchita kusinthidwa kakang'ono potengera mapindikidwe enieni a mankhwalawa, kukonza ma geometry apulasitiki, mawonekedwe ndi malo ndi zina zotero.

3, Kujambula zinthu.

Kuti mutsogolere kukhathamiritsa kwa mtsogolo, kujambula deta yatsopano ya 3D tokha molingana ndi zomwe kasitomala wagula ndikofunikira (zofunikira ziyenera kusungidwa). Kuzindikira mtengo wazinthu zopindika, kuphatikiza kusanthula kwa nkhungu komanso chidziwitso kuti musinthe zomwe zili patsamba, pansipa mutha kuwona zomwe zikuchitika:

Apa, maupangiri ena ndi okondwa kugawana nawo panthawi yojambulanso, monga: nthawi zonse yambani kujambula malo a "Base end surface", molingana ndi mtengo wopindika kuti mujambule mowongoka, piritsi lathyathyathya m'mphepete mwa chinthu, tchulani zokhotakhotazo. ku "Tambasula" (UG command) kuwongoka pamwamba. Malo osanja apangidwa ndi "Border" (UG command). Gawo ili ndilofunika, kuti muthe kusintha kusintha kwamtsogolo, jambulani popindika poyamba, musati "kutambasula" (Lamulo la UG) molunjika, kenako pogwiritsa ntchito mapindikidwe pamwamba pa kuwongoka kupeza mawonekedwe a mankhwala ndi "Offset" (UG lamulo). Kupewa kusintha mbali zambiri nkhungu pa kukhathamiritsa zotsatirazi nkhungu, kuchita pulasitiki zakuthupi kudula pa mankhwala "Base mapeto pamwamba" m'dera, ndiye achire mu T1-T3 kusinthidwa kutengera mapindikidwe enieni mankhwala (kuphatikiza pulasitiki).

Malangizo othandiza:

1. Osatengera mbiri yamakasitomala momwe mungathere, yesani kujambula nokha. Kotero kuti, kusinthidwa kwa nkhungu zotsatirazi ndizosavuta kusintha, kuphatikizapo makulidwe a khoma. ngati mawonekedwewo akukopedwa kuchokera kuzinthu zamakasitomala ndiye kuti pambuyo pakusintha kangapo, data ya 3D ipeza kusokonekera.
2. Pogwiritsa ntchito kujambula, momwe mungathere kuti muwone deta ya 2 / 3D ya kasitomala kuti mupewe zosiyana.

4, zotheka mapindikidwe kachitidwe za chinthu chofunika kwambiri

1, Kusinthika kwazinthu "Base end surface"

Momwe mungathere pochepetsa kuchitapo kanthu pazinthu zapulasitiki poyambira, zitha kupewa kukonzanso zigawo za nkhungu momwe zingathere. Mzere wofiyira pansipa ukuwonetsa momwe zinthu zimapangidwira. chonde dziwani kuti nthiti za “Bwana” kapena “zooneka ngati U” kapena zinthu zina zogwirizana nazo zisunthidwe ndi “Base end surface” palimodzi(Zina mwazinthu zomwe zili pansi pa abwana zimatsika ndi 0.5mm, ndiye “Bwana” nawonso atsike pansi 0.5 ), kenako jambulani ena. Ndibwino kugwiritsa ntchito "surface" (UG command) kuwajambula.

2, The mapindikidwe mankhwala a "Tube orifice"

Mawonekedwe a radius "R" pamizu ya chubu ayenera kukhala ofanana ndendende ndi zomwe kasitomala amapeza, chifukwa utali wa "R" uwu umakhudza mphamvu ya gawo lofunikira la chinthucho. Pazochitika zabwinobwino, chubu chozungulira chiyenera kuchepetsedwa pulasitiki ndi mbali kaye, kenaka musinthe mtengo molingana ndi mapindikidwe enieni, pachubu chachikulu, mawonekedwe a chubu mwina adapangidwa ngati mawonekedwe ozungulira pasadakhale.

3, "U" mawonekedwe a pulasitiki pang'ono

Pulasitiki ya "U-shape" iyeneranso kupanga pafupifupi madigiri 2-3, gawo lapakati la nthiti za "U -shape" liyeneranso kudula mbaliyo (chithunzi 1). Pambuyo mankhwala onse atakokedwa bwino ndiyeno kupanga "R" utali wozungulira (komanso kuti atsogolere kusintha, nthawi zina "R" utali wozungulira kumangidwanso adzalephera kapena nthawi yaitali), ngati geometry ena mu kasitomala 3D deta sanali chamfered, tikhoza chamfer iwo ngati sakhudza gawo msonkhano (makasitomala ambiri amakonda mawonekedwe akuthwa chamfered ndi "R" utali wozungulira). Kuphatikiza apo, ma geometry ena odziwika pagulu lazinthu zazikuluzikulu, mtundu wamtunduwu wamtunduwu uyenera kusamala kwambiri pakufanana ndi perpendicularity (chithunzi 2).

5, Mapeto

Pamwambapa pali zomwe takumana nazo pakupanga makina a auto air & tanka yamadzi-"kusinthika mosavuta" nkhungu yazinthu. pomaliza gawo ili bwino, ndikuganiza kuti theka la kupambana kwa nkhungu zotere likadapezeka, ndiye theka lina lili kuti? chonde onani gawo lotsatira la nkhaniyi "Kodi mukudziwa kupanga chisanadze deformation nkhungu? -kupanga gawo" sabata yamawa.
Chabwino, owerenga okondedwa. zikomo kwambiri chifukwa cha nthawi yanu yowerenga pano.ndikuyembekezera kukuwonani gawo lotsatira!
