1. Ukuqina kwe-Material strain: Lapho izinto ezisetshenziswayo zingaphansi kokulayishwa kwe-cyclic, isenzakalo "sokuqina kwe-cyclic strain" noma "i-cyclic strain softening" kwenzeka, okusho ukuthi ngaphansi kwe-amplitude ye-cyclic strain, i-stress amplitude iyanda noma yehla ngokunyuka kwenombolo yemijikelezo. Ngemuva 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 ingeye-cyclic strain hardening material. Ukuqina kwezinto kuzokhuphula amandla okutakula okunwebekayo e-FN yesiqephu esifakwe intambo 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. Lapho inani lokuvala likhulu, ukuwohloka kocezu lwentambo kukhudlwana lapho luvuleka, kuyanda ukuhluzeka kocezu lwentambo, ukuqina komjikelezo we-cyclic, kanye nokucindezela kwe-FN kocezu lwentambo, okunomkhuba wokwandisa i-screw out torque. Ngakolunye uhlangothi, ububanzi besiqephu sentambo buyancipha, indawo ephelele yesiqephu sentambo iyancipha, ukungqubuzana ne-bolt kuncipha, ubunzima besiqephu sentambo buyakhula, futhi ukusebenza kokukhathala komjikelezo ophansi kuncipha, okunomkhuba wokunciphisa i-screw out torque enkulu. Ngaphansi kwesenzo esihlanganisiwe sezici eziningi, kunzima ukubikezela ukuhluka kwetorque ephezulu nenani lokusetshenziswa okuphindaphindiwe, futhi kungabonwa kuphela ngokuhlolwa.
