1. Goho simba reflange
Ndiyo muganho wegoho wesimbi zvinhu kana goho chiitiko chikaitika, ndiko kuti, kushushikana kunoramba microplastic deformation.Kune zvigadzirwa zvesimbi zvisina chiitiko chegoho chakajeka, muganho wegoho unotsanangurwa sekukosha kwekunetseka kwe 0.2% yakasara deformation, iyo inonzi iyo inogadziriswa goho muganhu kana simba regoho.
Simba rekunze rakakura kudarika simba regoho richaita kuti zvikamu zvisashande zvachose uye zvisagadzirisika.Kana muganho wegoho weyakaderera kabhoni simbi iri 207MPa, kana yakakura kupfuura iyi muganhu pasi pekuita kwemasimba ekunze, zvikamu zvichaburitsa deformation yekusingaperi, zvishoma pane izvi, zvikamu zvichadzosera kutaridzika kwepakutanga.
(1) Pazvinhu zvine chiitiko chegoho chiri pachena, simba regoho ndiko kushushikana pane goho (kukosha kwegoho);
(2) Nezvemidziyo isina chiitiko chegoho chakajeka, kushushikana kana muganhu kutsauka kwehukama hwemutsara pakati pekunetseka uye kuomarara kunosvika pane yakatarwa kukosha (kazhinji 0.2% yepakutanga nhambwe).Inowanzo shandiswa kuongorora iyo mechanic uye mechanical zvinhu zvezvinhu zvakasimba, uye ndiyo chaiyo muganhu wekushandiswa kwezvinhu.Nokuti mukushungurudzika kunodarika muganhu wegoho wezvinyorwa mushure memutsipa, kushungurudza kunowedzera, kuitira kuti kukuvara kwezvinhu, kusagona kushandiswa kazhinji.Kana kushushikana kuchipfuura muganho we elastic uye kupinda muchikamu chegoho, iyo deformation inowedzera nekukurumidza, iyo inoburitsa kwete chete elastic deformation asiwo chikamu chepurasitiki deformation.Kana kushushikana kunosvika paB, kuputika kwepurasitiki kunowedzera zvakanyanya uye kushungurudzika-kunetseka kunoshanduka zvishoma, izvo zvinonzi goho.Kunyanya kushushikana uye kushomeka kwekushomeka padanho rino kunonzi goho repamusoro uye goho repazasi zvichiteerana.Sezvo kukosha kweiyo yakaderera goho poindi yakagadzikana, inonzi iyo goho point kana goho simba (ReL kana Rp0.2) seyindekisi yekupokana kwezvinhu.
Imwe simbi (yakadai seyakakwirira kabhoni simbi) pasina pachena goho chiitiko, kazhinji pamwe kuitika trace epurasitiki deformation (0.2%) kushushikana sezvo goho simba resimbi, inozivikanwa se conditional goho simba.

2. Kutsunga kweflangebereka simba
Iyo yakataurwa isiri-proportional elongation simba kana kutaurwa yakasara elongation kushushikana kunofanirwa kuyerwa kune simbi zvinhu pasina pachena goho chiitiko, nepo goho simba, repamusoro goho simba uye yakaderera goho simba anogona kuyerwa nokuda simbi zvinhu pamwe pachena goho chiitiko.Kazhinji, simba regoho chete rinoyerwa.
3. flangegoho simba mwero
(1) Kunyanya kushushikana mumuganhu wekuenzanisa-strain curve, iyo inopindirana nehukama hwemutsara, inowanzomiririrwa ne σ P munyika.Kana kushushikana kuchipfuura σ P, zvinhu zvinoonekwa sekupa goho.Kune matatu anowanzo shandiswa goho zviyero mumapurojekiti ekuvaka:
(2) Elastic muganho Iyo yakanyanya kushushikana iyo zvinhu zvinogona kudzoreredza zvizere mushure mekurodha mushure mekurodha, isingatore yakasara yekusingaperi deformation seyero.Munyika yose, inowanzotaurwa seReL.Izvo zvinhu zvinoonekwa sekupa kana kushushikana kwakapfuura ReL.
(3) Simba regoho rinobva pane kumwe kushanduka kwakasara.Semuenzaniso, 0.2% residual deformation stress inowanzoshandiswa sesimba regoho, uye chiratidzo chiri Rp0.2.
4. Zvinhu zvinokanganisa goho simba reflange
(1) Zvinhu zvemukati ndezvi: musanganiswa, sangano, chimiro, hunhu hweatomu.
(2) Zvinhu zvekunze zvinosanganisira tembiricha, strain rate uye stress state.
φ is a general unit, inoreva dhayamita yepombi negokora, simbi nezvimwe zvinhu, zvinogona zvakare kunzi dhayamita, senge φ 609.6mm inoreva dhayamita ye609.6mm.
