Nk'uburyo bwo kohereza, ibikoresho by'imibumbe bikoreshwa cyane mu buryo butandukanye bw'ubuhanga, nko kugabanya ibikoresho, crane, kugabanya ibikoresho by'imibumbe, nibindi. Ku bikoresho bigabanya ibikoresho by'imibumbe, bishobora gusimbura uburyo bwo kohereza ibikoresho bya axle ihamye mu bihe byinshi. Kubera ko inzira yo kohereza ibikoresho ari uguhuza umurongo, gukoresha meshi igihe kirekire bizatuma ibikoresho binanirwa, bityo ni ngombwa kwigana imbaraga zabyo. Li Hongli n'abandi bakoresheje uburyo bwo kohereza meshi mu buryo bwikora kugira ngo bafatanye ibikoresho by'imibumbe, maze babona ko torque n'imbaraga ntarengwa ari umurongo. Wang Yanjun n'abandi banakoresheje uburyo bwo kohereza ibikoresho by'imibumbe binyuze mu buryo bwo gukora ibintu bwikora, kandi bigana imiterere n'uburyo bwo gukora ibintu by'imibumbe. Muri iyi nyandiko, ibintu bya tetrahedron na hexahedron bikoreshwa cyane mu kugabanya meshi, kandi ibisubizo bya nyuma birasesengurwa kugira ngo harebwe niba imiterere y'imbaraga iragezweho.

1, Gushyiraho icyitegererezo n'isesengura ry'ibyavuye mu bushakashatsi

Ishusho y'ibikoresho by'imibumbe ifite imiterere itatu

Ibikoresho by'isiIgizwe ahanini n'ibikoresho by'impeta, ibikoresho by'izuba n'ibikoresho by'imibumbe. Ibipimo by'ingenzi byatoranijwe muri iyi nyandiko ni: umubare w'amenyo y'impeta y'impeta y'inyuma ni 66, umubare w'amenyo y'ibikoresho by'izuba ni 36, umubare w'amenyo y'ibikoresho by'imibumbe ni 15, umurambararo w'inyuma w'impeta y'inyuma ni 150 mm, modulus ni 2 mm, inguni y'umuvuduko ni 20 °, ubugari bw'amenyo ni 20 mm, coefficient y'uburebure bw'inyongera ni 1, coefficient y'inyuma ni 0.25, kandi hari ibikoresho bitatu by'imibumbe.

Isesengura ry’ibikoresho by’imibumbe ritajegajega

Sobanura imiterere y'ibikoresho: kwinjiza sisitemu y'ibikoresho by'imibumbe itatu yashushanyijwe muri porogaramu ya UG muri ANSYS, hanyuma ushyireho ibipimo by'ibikoresho, nk'uko bigaragara mu mbonerahamwe ya 1 hepfo:

Meshing: Mesh y'ikintu kidahinduka igabanyijemo kabiri na tetrahedron na hexahedron, kandi ingano y'ibanze y'ikintu ni 5mm. Kubera koibikoresho by'isi, ibikoresho by'izuba n'impeta y'ibikoresho by'imbere birakoranaho kandi bihuza, urusobe rw'ibice by'ibikoresho n'urusobe rurakomera, kandi ingano ni 2mm. Ubwa mbere, hakoreshwa imiyoboro ya tetrahedral, nk'uko bigaragara ku Ishusho ya 1. Ibintu 105906 n'udupfundo 177893 byose hamwe birakorwa. Hanyuma urusobe rwa hexahedral rurakoreshwa, nk'uko bigaragara ku Ishusho ya 2, maze uturemangingo 26957 n'udupfundo 140560 byose hamwe birakorwa.

Imikoreshereze y'umutwaro n'imiterere y'umupaka: hakurikijwe imiterere y'imikorere y'ibikoresho by'imibumbe mu gikoresho cyo gupima, ibikoresho by'izuba ni ibikoresho biyobora, ibikoresho by'imibumbe ni ibikoresho bitwarwa, kandi umusaruro wa nyuma unyura mu gikoresho cyo gutwara imibumbe. Kosora impeta y'ibikoresho by'imbere muri ANSYS, hanyuma ushyireho torque ya 500N · m ku bikoresho by'izuba, nk'uko bigaragara ku Ishusho ya 3.

Nyuma yo gutunganya no gusesengura ibyavuye mu bushakashatsi: Isesengura ry’impinduka n’isesengura ry’impinduka ringana n’iryo mu isesengura rihoraho ryavuye mu bice bibiri by’urukuta biragaragazwa hano hepfo, kandi isesengura rigereranya rirakorwa. Muri iryo sesengura ry’impinduka ry’ubwoko bubiri bw’urukuta, byagaragaye ko ihinduka ntarengwa riba aho ibikoresho by’izuba bidahuza n’ibikoresho by’isi, kandi ihinduka ntarengwa riba ku mizi y’urukuta rw’urukuta. Ihinduka ntarengwa ry’urukuta rw’urukuta rw’urukuta ni 378MPa, naho ihinduka ntarengwa ry’urukuta rw’urukuta rw’urukuta rw’urukuta ni 412MPa. Kubera ko umusaruro ntarengwa w’ibikoresho ari 785MPa kandi umutekano ukaba 1.5, ihinduka ntarengwa ryemewe ni 523MPa. Ihinduka ntarengwa ry’ibyavuye mu bushakashatsi byombi ni munsi y’ihinduka ryemewe, kandi byombi byujuje ibisabwa by’imbaraga.

2, Umwanzuro

Binyuze mu gusimbuza ibice bito by'ibikoresho by'imibumbe, haboneka nephogramu yo guhindura imiterere y'ibintu hamwe na nephogramu y'imbaraga zingana na zo muri sisitemu y'ibikoresho, aho amakuru ntarengwa n'amakuru make n'ikwirakwizwa ryabyo muibikoresho by'isiicyitegererezo kiraboneka. Aho amenyo y'ibikoresho ashobora kwangirika cyane ni naho amenyo y'ibikoresho ashobora kwangirika cyane, bityo hakwiye kwitabwaho cyane mu gihe cyo gushushanya cyangwa gukora. Binyuze mu isesengura ry'uburyo bwose bw'ibikoresho by'imibumbe, ikosa ryatewe no gusesengura iryinyo rimwe gusa ry'ibikoresho rirakemurwa.
