1. Ukuqina kwezinto eziphathekayo: Xa izixhobo ziphantsi komthwalo we-cyclic, i-phenomenon "ye-cyclic strain hardening" okanye "i-cyclic strain softening" iyenzeka, oku kuthetha ukuba phantsi koxinzelelo oluqhubekayo lwe-amplitude ye-cyclic, i-amplitude yoxinzelelo iyanda okanye iyancipha ngokunyuka koxinzelelo. inani lemijikelo. Emva kwemijikelo emininzi, i-amplitude yoxinzelelo ingena kwisimo esizinzile se-cyclic. Ukukhathala okuphantsi kwe-lock nut kuqhutyelwa phantsi kwemeko yokuba ubunzima buhlala buhlala, kwaye ukunyanzeliswa kokuqina okanye ukuthambisa kwentambo kuya kuchaphazela i-screw out torque. Intsimbi yealloyi esetyenziselwa ukwenza amandongomane okutshixa yeyemathiriyeli yokuqina yoxinzelelo lwe-cyclic. Ukuqina kwezinto eziphathekayo kuya kwandisa amandla okubuyisela i-elastic FN yeqhekeza elinemisonto kunye nokwandisa i-torque yokuqinisa.
I-2.I-angle ye-friction yinto ebalulekileyo echaphazela i-torque yokuqinisa, kwaye ubukho be-friction busisiseko sokusebenza okuqhelekileyo kwe-nut yokuvala. Xa i-nut yokutshixa isebenza, kukho uxinzelelo kunye ne-friction yesihlalo kwindawo yokudibanisa phantsi kwamandla okubuyisela i-elastic yeqhekeza elinentambo. Ngethuba lokusetyenziswa ngokuphindaphindiweyo, indawo yokudibanisa ixhomekeke kwi-cyclic friction, kwaye izikhundla ezinqabileyo kunye nezilungileyo kunye nemiphetho zihamba kakuhle, okubangelwa i-coefficient encinci ye-friction kunye nokunciphisa i-torque ephezulu yokuqinisa i-nut.
3.Ngenxa yonyino lwetekhnoloji yokuvelisa kunye nezizathu ezichanekileyo, kusenokubakho iikona ezibukhali kwincam yentambo okanye ukungahambelani komdimensional fit phakathi kwamalungu. Ngexesha lendibano yokuqala, kusenokubakho ukuguquguquka okanye ukuguquguquka kwi-screw-in kunye ne-screw-out torque, edinga inani elithile lemitsi ukuze kufunyanwe iimpawu zokuphinda zitshixelwe ezichanekileyo.
4.Emva kokumisela iiparitha zejometri zezinto eziphathekayo kunye ne-nut, utshintsho kwixabiso lokuvala lunempembelelo ebalulekileyo kwiimpawu zokuphinda zisetyenziswe kwi-nut yokuvala. Ixabiso lokuvala likhulu, i-deformation enkulu yentambo yentambo xa ivula, iphezulu i-strain ye-thread piece, i-strain ye-cyclic eqina isenzeko, kunye noxinzelelo olukhulu lwe-FN yeqhekeza lentambo, elinomkhuba we ukwandisa itorque yokujija. Ngakolunye uhlangothi, ububanzi bomsonto wentambo buyancipha, indawo epheleleyo yentambo yentambo iyancipha, ukukhuhlana kunye nebholiti kuyancipha, ukuxinwa kwentambo yentambo kuyanda, kunye nokusebenza kokudinwa kwe-Low-cycle kuyancipha, okunomkhuba. yokunciphisa ubuninzi be-screw out torque. Ngaphantsi kwesenzo esidibeneyo sezinto ezininzi, kunzima ukuqikelela ukuhluka kwe-torque ephezulu kunye nenani lokusetyenziswa ngokuphindaphindiweyo, kwaye kunokubonwa kuphela ngovavanyo.
