1. Kuvuta kwa zinthu: Pamene zipangizo zimayikidwa pa cyclic loading, zochitika za "cyclic strain hardening" kapena "cyclic strain softening" zimachitika, zomwe zikutanthauza kuti pansi pa nthawi zonse amplitude cyclic strain, kupsinjika maganizo kumawonjezeka kapena kuchepa ndi kuwonjezeka kwa chiwerengero cha maulendo. Pambuyo kangapo mkombero, ndi maganizo matalikidwe amalowa cyclic khola boma. The Low-mkombero kutopa wa loko nati ikuchitika pansi chikhalidwe kuti kupsyinjika ndi mosalekeza, ndi kupsyinjika kuumitsa kapena kufewetsa ulusi ulusi zimakhudza pazipita wononga makokedwe. Chitsulo cha alloy chomwe chimagwiritsidwa ntchito popanga mtedza wokhoma ndi cha cyclic strain hardness material. Kuwumitsa kwazinthu kumawonjezera mphamvu yobwezeretsa zotanuka FN ya chidutswa cholumikizidwa ndikuwonjezera torque yomangirira.
2.Kuthamanga kwapakati ndi chinthu chofunikira chomwe chimakhudza mphamvu yomangirira, ndipo kukhalapo kwa mikangano ndiko maziko a ntchito yachibadwa ya mtedza wokhoma. Pamene mtedza wokhoma ukugwira ntchito, pali kupanikizika ndi kukangana kwa mpando pamtunda wolumikizana pansi pa zotanuka kubwezeretsa mphamvu ya chidutswa cha ulusi. Pogwiritsa ntchito mobwerezabwereza, malo okhudzana ndi ma cyclic friction, ndipo malo owoneka bwino ndi abwino ndi m'mphepete mwake amawongolera, zomwe zimapangitsa kuti phokoso likhale lochepa kwambiri komanso kuchepa kwa torque yolimba kwambiri ya mtedza.
3.Chifukwa cha kuchepa kwaukadaulo wopanga ndi zifukwa zolondola, patha kukhala ngodya zakuthwa pamphepete mwa ulusi kapena kukwanira kosagwirizana pakati pa magawo. Pamsonkhano woyamba, pakhoza kukhala kusinthasintha kapena kusinthasintha kwa torque ya screw-in ndi screw-out, komwe kumafunika mathamangitsidwe angapo kuti apeze zolondola zogwiritsanso ntchito mtedza wokhoma.
4.Pambuyo pozindikira magawo a geometric azinthu ndi mtedza, kusintha kwa mtengo wotseka kumakhudza kwambiri machitidwe ogwiritsiranso ntchito a mtedza wokhoma. Kuchuluka kwa mtengo wotseka, kuwonjezereka kwa ulusi wa ulusi pamene kutsegulidwa, kuwonjezereka kwa ulusi wa ulusi, kuwonjezereka kwa cyclic kuumitsa chodabwitsa, komanso kukulirakulira kwa FN ya chidutswa cha ulusi, chomwe chimakhala ndi chizolowezi chowonjezera wononga torque. Kumbali ina, m'lifupi mwa ulusi wa ulusi umachepa, dera lonse la ulusi limachepa, kukangana ndi bawuti kumachepa, kupsyinjika kwa ulusi wa ulusi kumawonjezeka, ndipo kuchepa kwapang'onopang'ono kutopa kumachepa, komwe kumakhala ndi chizolowezi chochepetsera torque yayikulu. Pansi pa zochita zophatikizana zazinthu zingapo, zimakhala zovuta kufotokozera kusiyanasiyana kwa torque yayikulu ndi kuchuluka kwazomwe zimagwiritsidwa ntchito mobwerezabwereza, ndipo zitha kuwonedwa kokha kudzera muzoyeserera.
