1. Ukuqina kobunzima bezinto eziphathekayo: Xa izixhobo ziphantsi komthwalo we-cyclic, i-phenomenon ye-"cyclic strain hardening" okanye "i-cyclic strain softening" iyenzeka, oku kuthetha ukuba phantsi koxinzelelo lwe-amplitude rhoqo, i-amplitude yoxinzelelo iyanda okanye iyancipha ngokunyuka kwenani lemijikelezo. 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 ukuvelisa 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 elikhulu lokuvala, i-deformation enkulu yentambo yentambo xa ivula, iphezulu i-strain ye- thread piece, i-strain ngakumbi i-cyclic eqina isenzeko, kunye noxinzelelo olukhulu lwe-FN yeqhekeza lentambo, elinomkhuba wokwandisa i-screw out torque. Kwelinye icala, ububanzi iqhekeza intambo kuncipha, indawo iyonke intambo intambo kuncipha, ukukhuhlana kunye nebholiti kuncipha, ukutsala iqhekeza intambo ukwanda, kwaye ukusebenza Low-umjikelo ukudinwa kuncipha, nto leyo enentsingiselo yokunciphisa ubuninzi jija ngaphandle torque. Ngaphantsi kwesenzo esidibeneyo sezinto ezininzi, kunzima ukuqikelela ukuhluka kwe-torque ephezulu kunye nenani lokusetyenziswa ngokuphindaphindiweyo, kwaye kunokubonwa kuphela ngovavanyo.
