Nuburyo bwogukwirakwiza, ibikoresho byimibumbe bikoreshwa cyane mubikorwa bitandukanye byubwubatsi, nko kugabanya ibikoresho, crane, kugabanya ibikoresho by’imibumbe, nibindi. Kugabanya ibikoresho by’imibumbe, birashobora gusimbuza uburyo bwo kohereza gari ya moshi zihamye mu bihe byinshi. Kuberako inzira yo kohereza ibikoresho ari umurongo uhuza, igihe kirekire meshing izatera kunanirwa ibikoresho, birakenewe rero kwigana imbaraga zayo. Li Hongli n'abandi. yakoresheje uburyo bwa meshing uburyo bwo guhuza ibikoresho byumubumbe, hanyuma abona ko torque hamwe na stress ntarengwa ari umurongo. Wang Yanjun n'abandi. yashushanyije kandi ibikoresho byimibumbe ikoresheje uburyo bwokubyara byikora, kandi bigereranya imibare nuburyo bwo kwigana ibikoresho byimibumbe. Muri iyi nyandiko, tetrahedron na hexahedron bikoreshwa cyane cyane kugabanya mesh, kandi ibisubizo byanyuma birasesengurwa kugirango harebwe niba imbaraga zujujwe.

Uburyo butatu bwo kwerekana ibikoresho byimibumbe

Ibikoresho by'imibumbeigizwe ahanini nibikoresho byimpeta, ibikoresho byizuba nibikoresho byumubumbe. Ibipimo nyamukuru byatoranijwe muriyi mpapuro ni: umubare w amenyo yimpeta yimbere ni 66, umubare w amenyo yibikoresho byizuba ni 36, amenyo yibikoresho byumubumbe ni 15, diameter yinyuma yibikoresho byimbere impeta ni mm 150, modulus ni mm 2, inguni yumuvuduko ni 20 °, ubugari bw amenyo ni mm 20, coefficient yuburebure bwinyongera ni 1, coefficient yinyuma ni 0,25, kandi hariho ibikoresho bitatu byimibumbe.

Isesengura ryigero ryibikoresho byimibumbe

Sobanura ibintu bifatika: kwinjiza ibintu bitatu-byimibumbe yububiko bwa sisitemu yashushanyije muri software ya UG muri ANSYS, hanyuma ushireho ibipimo bifatika, nkuko bigaragara mu mbonerahamwe ya 1 hepfo:

Meshing: Ikintu cya nyuma mesh igabanijwe na tetrahedron na hexahedron, kandi ubunini bwibanze bwibintu ni 5mm. Kuva iibikoresho byo mu mubumbe, ibikoresho byizuba hamwe nimpeta yimbere imbere irahuza na mesh, mesh yo guhuza nibice bya mesh iragwira, kandi ubunini ni 2mm. Ubwa mbere, tetrahedral gride irakoreshwa, nkuko bigaragara ku gishushanyo cya 1. 105906 ibice na 177893 node byakozwe muri rusange. Hanyuma gride ya hexahedral iremewe, nkuko bigaragara ku gishushanyo cya 2, na selile 26957 na node 140560 byakozwe muri rusange.

Gushyira imizigo hamwe nimbibi: ukurikije ibiranga imirimo yibikoresho byumubumbe mubigabanya, ibikoresho byizuba nibikoresho byo gutwara, ibikoresho byumubumbe nibikoresho bitwarwa, naho ibisohoka byanyuma binyuze mubitwara umubumbe. Ongera impeta y'imbere muri ANSYS, hanyuma ushyire urumuri rwa 500N · m kubikoresho by'izuba, nkuko bigaragara ku gishushanyo cya 3.

Isesengura ryibisubizo hamwe nisesengura ryibisubizo: Kwimura nephogramu hamwe ningutu ihwanye na nephogramme yisesengura rihamye ryakuwe mubice bibiri bya gride byatanzwe hepfo, kandi isesengura rigereranya rirakorwa. Uhereye kuri nephogramu yo kwimura ubwoko bubiri bwa gride, usanga kwimuka kwinshi kugaragara kumwanya aho ibikoresho byizuba bidahuye nibikoresho byumubumbe, kandi guhangayika cyane bibera kumuzi ya meshi. Guhangayikishwa cyane na gride ya tetrahedral ni 378MPa, naho guhangayikishwa cyane na gride ya hexahedral ni 412MPa. Kubera ko umusaruro wibikoresho ari 785MPa naho umutekano ni 1.5, guhangayikishwa ni 523MPa. Imihangayiko ntarengwa y'ibisubizo byombi ntabwo iri munsi yimyitwarire yemewe, kandi byombi byujuje imbaraga zimiterere.

2 lusion Umwanzuro

Binyuze mubintu bitagira ingano bigereranya ibikoresho byumubumbe, kwimura deformasiyo ya nephogramu hamwe na nephogramme ihwanye na nephogram ya sisitemu ya gare iboneka, aho amakuru ntarengwa kandi ntarengwa hamwe nogukwirakwiza muriibikoresho byo mu mubumbeicyitegererezo kirashobora kuboneka. Ahantu ho guhangayikishwa cyane niho hantu hashobora kuba amenyo y'ibikoresho ashobora kunanirwa, bityo rero hakwiye kwitabwaho cyane mugihe cyo gukora cyangwa gukora. Binyuze mu isesengura rya sisitemu yose y'ibikoresho byo mu mubumbe, ikosa ryatewe no gusesengura iryinyo rimwe gusa riratsinda.
