Ukulinganisa kufanele ngokuvamile kwenziwe okungenani kanye ngonyaka, nakuba ukulinganisa okuvamisile kungase kudingeke ezimbonini ezilawulwa kakhulu noma lapho imishini isetshenziswa kakhulu. Izincomo zomkhiqizi kanye namazinga okulawula umphakathi okusebenzayo kufanele ngaso sonke isikhathi kulandelwe ukuze kuqinisekiswe ukulandeleka nokunemba. Amarekhodi okulinganisa avamile abalulekile ukuze kuboniswe ukuthobela imithetho ngesikhathi sokuhlolwa nokugcina ukuzethemba kudatha yakho yokuhlola.

Izici ezibalulekile zihlanganisa ububanzi be-torque obanele nejubane elilungisekayo, ukunemba okuphezulu nokucacisisa ekukalweni kwe-torque ne-angle, isofthiwe ethuthukile yokuhlaziya idatha nokubika, nezici zokuphepha eziqinile ezifana nokuma okuphuthumayo nokuvikelwa kokulayisha ngokweqile. Kufanele futhi ucabangele ikhwalithi yezinsimbi zokubamba nokwethembeka kokusekelwa komkhiqizi. Ukufanisa imininingwane yomshini nezindinganiso zakho zokuhlola ezithile nezinhlobo zezinto ezisetshenziswayo kubalulekile ukuze uphumelele.

Ukuhlolwa kwe-torsion kubalulekile ekulawuleni ikhwalithi ngoba izingxenye eziningi, okuhlanganisa ama-shaft, iziphethu, izinto zokubopha, nezinhlelo zokushayela, zingaphansi kwemithwalo yokugoba ngesikhathi sokusebenza okuvamile. Ngokuqinisekisa ukuthi izinto zihlangabezana nezidingo ezidingekayo ze-torsion, abakhiqizi bangavimbela ukwehluleka kwangaphambi kwesikhathi, ukukhumbula, nezigameko zokuphepha. Ukuhlolwa kwe-torsion okungaguquki kusiza nasekuthuthukiseni izinqubo zokukhiqiza futhi kuqinisekisa ukuthi yonke ibhetshi yomkhiqizo ihlangabezana namazinga aphezulu afanayo.

Yebo, imishini yokuhlola i-torsion eguquguqukayo iklanyelwe ngokuqondile ukusebenzisa imithwalo ye-torsion ejikelezayo nokukala ukuthi izinto zingamelana namazinga amangaki ngaphambi kokwehluleka. Le datha isetshenziselwa ukwakha amajika e-S-N nokuhlola ukumelana nokukhathala kwezingxenye ezithola ukusonteka okuphindaphindiwe lapho zisebenza. Ukuqonda impilo yokukhathala kubalulekile ekuklameni izingxenye ezijikelezayo eziqinile nezithembekile.

I-Jinan Wangtebei ihlinzeka ngohlu oluphelele lwemishini yokuhlola i-torsion kanye nokuqondiswa kochwepheshe ekukhetheni imishini, ukufakwa kwayo, ukuqeqeshwa, kanye nokusekelwa kwezobuchwepheshe okuqhubekayo. Ithimba labo lisiza amakhasimende ukuthi ahlangabezane namazinga omhlaba wonke futhi linikeza izinsizakalo zokulinganisa nokulungisa ukuze imishini iqhubeke isebenza ngokunembile. Amakhasimende angafinyelela kubo kalula ngekhasi lokusekelwa ukuze abuze imibuzo, athole izilinganiso, kanye nosizo lwangemuva kokuthengisa.
