1. Kuomeswa kwezvinhu: Kana zvinhu zvichiiswa pasi pe cyclic loading, chiitiko che "cyclic strain harding" kana "cyclic strain softening" chinoitika, izvo zvinoreva kuti pasi penguva dzose amplitude cyclic strain, kushungurudza amplitude kunowedzera kana kuderera nekuwedzera kwe nhamba yematenderedzwa. Mushure mekutenderera kwakati wandei, iyo stress amplitude inopinda mune cyclic yakagadzikana mamiriro. Iyo yakaderera-kutenderera kuneta kwekiyi nati inoitwa pasi pemamiriro ekuti kuomarara kunoramba kuripo, uye kuomesa kana kupfava kwechidimbu chetambo kuchakanganisa iyo yakanyanya screw out torque. Iyo alloy simbi inoshandiswa kugadzira kukiya nzungu ndeyeiyo cyclic strain inoomesa zvinhu. Kuomeswa kwezvinhu kuchawedzera iyo elastic kudzoreredza simba FN yechidimbu chakarukwa uye kuwedzera inosimbisa torque.
2.Iyo friction angle chinhu chakakosha chinokanganisa torque inosimbisa, uye kuvapo kwekukakavadzana ndiyo nheyo yekushanda kwemaitiro ekuvhara nut. Kana iyo nati yekuvhara iri kushanda, pane kudzvanywa uye kukweshera kwechigaro pane yekubata kumeso pasi peiyo elastic yekudzoreredza simba reiyo tambo yakarukwa. Munguva yekudzokorora kushandiswa, nzvimbo yekubatana inoiswa pasi pe cyclic friction, uye nzvimbo dzakaomarara uye dzakanaka uye mipendero inokwenenzverwa, zvichikonzera kudiki friction coefficient uye kuderera kweiyo yakanyanya kuomesa torque ye nut.
3.Nekuda kwekugadzira tekinoroji mipimo uye zvikonzero chaizvo, panogona kunge paine makona akapinza pamipendero yeshinda kana kusapindirana dimensional fit pakati pezvikamu. Panguva yegungano rekutanga, panogona kuve nekumwe kuchinjika kana kuchinjika mune screw-in uye screw-out torque, izvo zvinoda imwe nhamba yekumhanya kuti uwane kunyatso kukiya kukiya nati maitiro ekushandisa zvakare.
4.Mushure mekugadzirisa geometric parameters yezvinhu uye nut, kuchinja kwekuvhara kukosha kune zvakakosha pakushandiswa zvakare maitiro ekuvhara nut. Iyo yakakura kukosha kwekuvhara, iyo yakakura deformation yeshinda chidimbu painovhurwa, iyo inokwirisa iyo dhizaini yeshinda yeshinda, iyo inowedzera strain cyclic kuomesa chiitiko, uye yakakura kumanikidza FN yeshinda chidimbu, ine maitiro e kuwedzera screw out torque. Kune rumwe rutivi, hupamhi hwechidimbu cheshinda hunoderera, nzvimbo yose yechidimbu chetambo inoderera, kukwesha nebhaudhi kunoderera, kusimba kwechidimbu chetambo kunowedzera, uye Low-cycle kuneta kushanda kunoderera, iyo ine maitiro. yekudzikisa yakanyanya screw out torque. Pasi pechiito chakabatanidzwa chezvikonzero zvakawanda, zvakaoma kufanotaura kushanduka kweiyo torque yakakura nehuwandu hwekushandiswa kwakadzokororwa, uye inogona kungoonekwa kuburikidza nekuedza.
