1. Ho thatafala ha thepa: Ha lisebelisoa li kenngoa ka cyclic loading, ketsahalo ea "cyclic strain hardening" kapa "cyclic strain softening" e etsahala, e leng se bolelang hore tlas'a khatello ea kamehla ea amplitude cyclic, amplitude ea khatello ea kelello e eketseha kapa e fokotseha ka ho eketseha ha palo ea lipotoloho. Ka mor'a lipotoloho tse 'maloa, amplitude ea khatello ea kelello e kena boemong bo tsitsitseng ba cyclic. The Low-potoloho mokhathala oa notlelela linate o etsoa tlas'a boemo ba hore khatello ea kamehla, 'me mathata a thatafatsa kapa softening ea khoele sengoathoana tla ama palo e kahodimodimo screw out torque. Tšepe ea alloy e sebelisetsoang ho etsa linate tsa senotlolo ke ea thepa e thatafatsang ea cyclic strain. Ho thatafala ha lintho tse bonahalang ho tla eketsa matla a ho hlaphoheloa a elastic FN ea sengoathoana se lohiloeng le ho eketsa torque e tiisang.
2.The friction angle ke ntlha ea bohlokoa e amang torque e tiisang, 'me ho ba teng ha likhohlano ke motheo oa ts'ebetso e tloaelehileng ea linate tsa ho notlela. Ha nate e notlelang e sebetsa, ho na le khatello le khohlano ea setulo holim'a sebaka sa ho ikopanya ka tlas'a matla a ho khutlisetsa rekere ea sengoathoana se khoele. Nakong ea ts'ebeliso e pheta-phetoang, sebaka sa ho kopana se ba le likhohlano tsa cyclic, 'me maemo a mahoashe le a matle le mathōko a boreleli, e leng se etsang hore ho be le coefficient e nyenyane ea likhohlano le ho fokotseha ha torque e matla ea linate.
3.Ka lebaka la mefokolo ea theknoloji ea tlhahiso le mabaka a nepahetseng, ho ka 'na ha e-ba le likhutlo tse bohale lintlheng tsa khoele kapa ho lumellana ho sa lumellaneng pakeng tsa likarolo. Nakong ea kopano ea pele, ho ka 'na ha e-ba le liphetoho tse ling kapa ho feto-fetoha ha torque ea screw-in le screw-out, e hlokang palo e itseng ea ho matha e le ho fumana litšobotsi tse nepahetseng tsa ho sebelisa linate hape.
4.Ka mor'a ho khetholla likarolo tsa geometri tsa thepa le linate, phetoho ea boleng ba ho koala e na le tšusumetso e kholo litšoanelehong tsa tšebeliso e ncha ea linate tse notlellang. The e kholoanyane boleng ba ho koala, e kholoanyane deformation ea khoele sengoathoana ha e bula, e phahameng khatello ea khoele sengoathoana, le ho feta mathata cyclic thatafatsa ketsahalo, 'me e khōloanyane khatello ea FN ea khoele sengoathoana, e nang le mokhoa oa ho eketsa screw out torque. Ka lehlakoreng le leng, bophara ba sekhechana sa khoele bo fokotseha, sebaka sohle sa khoele se fokotseha, khohlano e nang le bolt e fokotseha, khatello ea sekhechana sa khoele e eketseha, 'me ts'ebetso ea mokhathala o tlase o fokotseha, e nang le mokhoa oa ho fokotsa boholo ba screw out torque. Tlas'a ketso e kopantsoeng ea lintlha tse ngata, ho thata ho bolela esale pele phapang ea torque e kholo ka palo ea tšebeliso e pheta-phetoang, 'me e ka bonoa feela ka liteko.
