1. Ukuqina kwe-Material strain: Uma izinto zilayishwa ngomjikelezo, into ethi "cyclic strain harding" noma "cyclic strain softening" iyenzeka, okusho ukuthi ngaphansi kwe-amplitude cyclic strain, i-stress amplitude iyanda noma yehla ngokunyuka kwengcindezi. inani lemijikelezo. Ngemva kwemijikelezo eminingana, i-amplitude yokucindezeleka ingena esimweni esizinzile se-cyclic. Ukukhathala okuphansi komjikelezo we-lock nut kwenziwa ngaphansi kwesimo sokuthi ubunzima buhlala njalo, futhi ukuqina kokuqina noma ukuthambisa ucezu lwentambo kuzothinta i-torque ephezulu yesikulufu. Insimbi ye-alloy esetshenziselwa ukukhiqiza amantongomane wokukhiya ingeyezinto eziqinile ze-cyclic strain. Ukuqina kwezinto kuzokhuphula amandla okutakula okunwebekayo e-FN yesiqephu esifakwe imicu futhi kwandise i-torque eqinisayo.
2.I-angle ye-friction iyisici esibalulekile esithinta i-torque eqinisayo, futhi ukuba khona kokungqubuzana kuyisisekelo sokusebenza okuvamile kwentongomane yokukhiya. Lapho inathi elikhiyayo lisebenza, kuba khona ukucindezela kanye nokungqubuzana kwesihlalo endaweni yokuxhumana ngaphansi kwamandla okubuyisela okunwebeka kwesiqephu esicushwe. Ngesikhathi sokusetshenziswa okuphindaphindiwe, indawo yokuxhumana ingaphansi kokungqubuzana kwe-cyclic, futhi izindawo ezimahhadlahhadla nezicolekileyo nemiphetho ziyashelela, okuholela ku-coefficient encane yokungqubuzana kanye nokuncipha kwe-torque enkulu yokuqinisa inati.
3.Ngenxa yemikhawulo yobuchwepheshe bokukhiqiza kanye nezizathu zokunemba, kungase kube khona amakhona acijile emaphethelweni entambo noma ukulingana okungafani kobukhulu phakathi kwezingxenye. Phakathi nokuhlanganisa kokuqala, kungase kube nokuguquguquka okuthile noma ukushintshashintsha kwetorque yesikulufu kanye ne-screw-out, edinga inani elithile lokugijima ukuze kutholwe izici ezinembile zokuphinda zisetshenziswe nanathi lokukhiya.
4.Ngemva kokunquma amapharamitha wejometri wento kanye namantongomane, ukuguqulwa kwevelu yokuvala kunomthelela obalulekile ezicini zokuphinda zisetshenziswe zentongomane yokukhiya. Uma inani lokuvala lilikhulu, kukhulu ukuwohloka kocezu lwentambo lapho luvuleka, kuyanda ukuhluzeka kwesiqephu sentambo, isenzakalo esiba lukhuni kakhulu se-cyclic, kanye nokucindezela okukhulu kwe-FN yesiqephu sentambo, esinomkhuba ukwandisa i-torque yesikulufu. Ngakolunye uhlangothi, ububanzi besiqephu sentambo buyancipha, indawo ephelele yesiqephu sentambo iyancipha, ukungqubuzana ne-bolt kuncipha, ukuhlushwa kwesiqephu sentambo kuyanda, futhi ukusebenza kokukhathala komjikelezo ophansi kuncipha, okunomkhuba. yokunciphisa ubukhulu be-screw out torque. Ngaphansi kwesenzo esihlanganisiwe sezici eziningi, kunzima ukubikezela ukuhluka kwetorque ephezulu nenani lokusetshenziswa okuphindaphindiwe, futhi kungabonwa kuphela ngokuhlolwa.
