1, Umklamo wangaphambi kokuguqulwa uyisihluthulelo

Ngokuphathelene nesikhunta sepulasitiki somkhiqizo wethangi lamanzi nomoya ozenzakalelayo, ukulawula ikhwalithi yomklamo nokukhiqiza kunzima kakhulu kunohlobo olujwayelekile, njengoba lezi zingxenye zohlobo zivame ukubunjwa yi-PA6 (PA66) + GF (30-35%), futhi lolu hlobo lwezinto kulula ukuluthola ngesikhathi senqubo yokubumba, futhi usayizi womkhiqizo ohambisanayo kulula ukungabekezeleli. Ngakho-ke, uma ujwayelene nokujwayela kokuguqulwa kwawo, khona-ke ukwenza umklamo wangaphambi kokuguqulwa ngokusekelwe kokuhlangenwe nakho kanye nomphumela wokuhlaziywa kwe-CAE enkambisweni yokuqala yokuklama sekuyisihluthulelo sempumelelo yokukhiqiza isikhunta.

Ithimba lesikhunta i-Enuo linolwazi lweminyaka engaphezu kwe-10 ekwenzeni isikhunta ngaphambi kokuguqulwa, futhi selikhonze amakhasimende e-Valeo, Mahle-behr, Delphi kanye namanye amakhasimende ezingxenye zezimoto adumile emhlabeni wonke. Lapha sethula kafushane ulwazi lwethu lokwenza isikhunta se-air and water tank. Impela, izinkampani ezahlukene zinemikhuba ehlukene, uma mfundi othandekayo enemibono ehlukene, wamukelekile futhi ukuxhumana nathi ngemfudumalo.

2, Ukuhlaziya imidwebo yezingxenye, ukucacisa izindawo ezibalulekile zomkhiqizo nosayizi

Ukuze uqonde izindawo ezibalulekile zomkhiqizo kanye nosayizi oyinhloko ohambisanayo kuhlale kuyisinyathelo sokuqala lapho imidwebo yomkhiqizo yamakhasimende ifika, bese unaka kakhulu lokho kubaluleka, njengokuthi "Umphezulu Wokuphela" womkhiqizo (“Umphezulu Wokuphela" wawudingeka kakhulu ukuqondeka, ukuthamba kanye nokubekezelelana kosayizi wefomu, kanti ezinye izingxenye zobukhulu bomkhiqizo zizolandela ukushintsha kwazo) "Indawo ye-Tube orifice" (ubukhulu be-"tube orifice" nabo bubaluleke kakhulu, ngokuvamile kudingeka indawo, ukubekezelelana kwesilinda kanye nobukhulu) kanye nezimbambo zomkhiqizo "Boss" kanye "no-U-shape" njll., ziboniswe ngezansi:

Uma ufuna isikhunta esisha, yenza i-pre-deformation kumkhiqizo (wenza "isinxephezelo sezinto ezibonakalayo" ohlangothini oluphambene nokuguqulwa okulinganisiwe kusengaphambili ngokuya ngolwazi kanye nokuhlaziywa kwe-CAE, phakamisa ukuthi zilungiswe ngemva kokwenziwa kwe-deformation yangempela). Ngemva kokuhlolwa kwesikhunta, yenza ushintsho oluthile oluncane olusekelwe ekuguqulweni kwangempela kokubunjwa komkhiqizo, ukulungisa i-geometry yepulasitiki, ukuma kanye nendawo nokunye.

3, Ukudweba imikhiqizo.

Ukuze kube lula ukwenza ngcono isikhunta esikhathini esizayo, ukudweba idatha entsha yomkhiqizo we-3D ngokwethu ngokomkhiqizo wamakhasimende kuyadingeka (kufanele kugcinwe imingcele ebalulekile). Ukunquma inani lokuguqulwa kwemikhiqizo, kuhlanganiswe nokuhlaziywa kokugeleza kwesikhunta kanye nesipiliyoni sokushintsha idatha yomkhiqizo, ngezansi ungabona izitayela zokuguqulwa ezinolwazi:

Lapha, amanye amathiphu ajabulisayo ukwabelana ngawo ngesikhathi senqubo yokudweba kabusha, njengokuthi: qala njalo ekudwebeni indawo "yomphetho wesisekelo", ngokwenani lokuguqulwa ukuze udwebe uqondile, ijika eliyisicaba emaphethelweni omkhiqizo, bhekisa kulawo majika ku-"Stretch" (umyalo we-UG) ubuso obuqondile. Izindawo eziyisicaba zenziwa ngomyalo we-"Border" (UG). Lesi sinyathelo sibalulekile, ukuze kube lula ukushintsha esikhathini esizayo, dweba ijika kuqala, ungaweluli ngqo umphezulu "womyalo we-UG", bese usebenzisa umphezulu wokuguqulwa kokuqina uthole ukuma komkhiqizo nge-"Offset" (umyalo we-UG). Ukuze ugweme ukushintsha izingxenye eziningi zesikhunta ngesikhathi sokulungisa isikhunta esilandelayo, yenza ukusika izinto zepulasitiki endaweni "yomphetho wesisekelo" somkhiqizo, bese uzibuyisela ekuguqulweni kwe-T1-T3 ngokusekelwe ekuguqulweni komkhiqizo kwangempela (kanye nepulasitiki).

Amathiphu okukhokha abe awusizo:

1. Ungakopishi ubuso bephrofayili yemikhiqizo yamakhasimende ngangokunokwenzeka, zama ukuzidweba wedwa. Ukuze, ukuze kube lula ukushintsha isikhunta okulandelayo, kufaka phakathi ubukhulu bodonga. Uma izimo zikopishwe kumkhiqizo wamakhasimende, khona-ke ngemva kokuguqulwa okuningi, idatha ye-3D izothola ukuhlanekezelwa.
2. Enkambisweni yokudweba, hlola idatha yomkhiqizo we-2/3D yamakhasimende ngangokunokwenzeka ukuze uvimbele ukuthi ihlukile.

4, Umkhuba wokuguquguquka okungenzeka mayelana nengxenye ebalulekile yomkhiqizo

1, Ukuguqulwa komkhiqizo "Umphezulu wesisekelo"

Ngangokunokwenzeka ukuze kuncishiswe isenzo ezintweni zepulasitiki ekuqaleni, kungagwema ukwenza kabusha izingxenye zesikhunta ngangokunokwenzeka. Umugqa obomvu ongezansi ukhombisa ukuthambekela kokuguqulwa komkhiqizo okulinganisiwe. sicela uqaphele ukuthi izimbambo "zeBoss" noma "ezimise okwe-U" noma izinto ezihlobene kufanele zihanjiswe "nobuso bokugcina besisekelo" ndawonye (Ezinye zezinto ezingaphansi kweboss zehla ngo-0.5mm, bese "iBoss" nayo yehla ngo-0.5), bese udweba ezinye. Kunconywa ukusebenzisa "ubuso" (umyalo we-UG) ukuze uzidwebe.

2, Ukuguqulwa komkhiqizo we-"Tube orifice"

Isimo serediyasi "R" empandeni yethubhu kufanele sifane ncamashi nedatha yomkhiqizo wamakhasimende, njengoba le rediyasi "R" ithinta amandla endawo ebalulekile yomkhiqizo. Ezimweni ezivamile, ithubhu eliyindilinga kufanele lincishiswe libe yipulasitiki eceleni kuqala, bese lishintsha inani ngokuya ngokuguquguquka kwangempela, ngethubhu elikhulu, isimo sethubhu mhlawumbe sakhiwe njengesimo se-oval kusengaphambili.

3, ukwakheka kwe-plastic bit yomkhiqizo "U"

Ipulasitiki “eyimilo ka-U” nayo idinga ukwenza ukuguquguquka okungama-degree angu-2-3, indawo ephakathi yezimbambo “eziyimilo ka-U” kufanele futhi yenze ukusika kwezinto eceleni (isithombe 1). Ngemva kokuba yonke imikhiqizo isidwetshwe kahle bese iklama irediyasi “R” (futhi ukuze kube lula ukushintsha, ngezinye izikhathi ukwakhiwa kabusha kwerediyasi “R” kuzohluleka noma kusetshenziswe isikhathi eside), uma ezinye i-geometry kudatha yamakhasimende ye-3D zingazange zishintshe, singazishintsha uma zingathinti ukuhlanganiswa kwezingxenye (amakhasimende amaningi akhetha ukuthi isimo esibukhali sishintshwe ngerediyasi “R”. Ngaphezu kwalokho, ezinye i-geometry ezivelele emzimbeni oyinhloko womkhiqizo zikhulu, lolu hlobo lokuguquguquka komkhiqizo kufanele lunake kakhulu ukulingana kanye nokuma okuqondile (isithombe 2).

5, Isiphetho

Ngenhla ulwazi lwethu ngokuklama isikhunta somkhiqizo wethangi lomoya namanzi elizenzakalelayo - "ukushintshwa kalula". Ukuqeda lesi sinyathelo kuhle, ngicabanga ukuthi ingxenye yempumelelo yokukhiqiza isikhunta esinjalo ngabe itholakale, pho iphi enye ingxenye? sicela ubheke ingxenye elandelayo yalesi sihloko esithi "Uyazi ukuthi ungasenza kanjani isigaba sokukhiqiza isikhunta sangaphambi kokuguqulwa?" ngesonto elizayo.
Kulungile, bafundi abathandekayo. Ngiyabonga kakhulu ngesikhathi senu sokufunda lapha. Ngilangazelela ukunibona esigabeni esilandelayo!
