Isisombululo seNkqubo yoLawulo lweTension
Jonga ngeenxa zonke kuwe, uninzi lweemveliso ozibonayo kwaye uzisebenzisayo zenziwa kusetyenziswa uhlobo oluthile lwenkqubo yokulawula uxinzelelo. Ukusuka kwiphakheji ye-cereal ekuseni ukuya kwileyibhile kwibhotile yamanzi, naphi na apho uya khona kukho izinto ezixhomekeke kulawulo oluchanekileyo loxinzelelo kwinkqubo yokuvelisa. Iinkampani kwihlabathi jikelele ziyazi ukuba ulawulo loxinzelelo olululo luphawu “lokwenza okanye ukuqhawuka” kwezi nkqubo zokuvelisa. Kodwa kutheni? Yintoni ulawulo loxinzelelo kwaye kutheni ibaluleke kangaka kwimveliso?
Ngaphambi kokuba singeneulawulo loxinzelelo, kufuneka siqale siqonde ukuba yintoni i-tension. Uxinzelelo ngamandla okanye uxinzelelo olusetyenziswa kwinto ebangela ukuba yolule kwicala lamandla asetyenziswayo. Kwimveliso, oku kudla ngokuqala xa imathiriyeli ekrwada itsalwa kwinkqubo ngendawo yenkqubo esezantsi. Sichaza ukuxhatshazwa njenge-torque esetyenziswe kumbindi we-roll, ihlulwe yi-radius roll. Uxinzelelo = iTorque/Radius (T=TQ/R). Xa i-tension iphezulu kakhulu, ukunyanzeliswa okungafanelekanga kunokubangela ukuba i-material yandiswe kwaye itshabalalise imilo yomqulu, okanye yonakalise i-roll ukuba i-tension idlula amandla okucheba kwezinto. Ngakolunye uhlangothi, ukuxinana okukhulu kunokonakalisa imveliso yakho yokugqibela. Uxinzelelo olungonelanga lunokubangela ukuba i-reel yokuthatha yolule okanye igxumeke, ekugqibeleni ibangele umgangatho ombi wemveliso egqityiweyo.
Tension Equation
Ukuze siqonde ulawulo loxinzelelo, kufuneka siqonde ukuba yintoni na "iwebhu". Eli gama libhekisa kuyo nayiphi na imathiriyeli ehanjiswa ngokuqhubekayo ukusuka kumqulu wephepha, iplastiki, ifilim, intambo, intambo, intambo okanye isinyithi. Ulawulo loxinzelelo sisenzo sokugcina uxinzelelo olufunwayo kwiwebhu njengoko kufunwa yimathiriyeli. Oku kuthetha ukuba uxinzelelo luyalinganiswa kwaye lugcinwe kwindawo efunekayo ukuze iwebhu iqhube kakuhle kuyo yonke inkqubo yokuvelisa. Uxinzelelo ngokuqhelekileyo lulinganiswa kusetyenziswa inkqubo yomlinganiselo we-imperial kwiipounds nge-intshi nganye yomgca (PLI) okanye imetric kwiiNewtons ngesentimitha (N/cm).
Ulawulo loxinzelelo olufanelekileyo lwenzelwe ukulawula ngokuchanekileyo ukuxhatshazwa kwiwebhu, ngoko kufuneka ilawulwe ngononophelo kwaye igcinwe kwinqanaba elincinci kuyo yonke inkqubo. Umgaqo wobhontsi kukuqhuba ubuncinci boxinzelelo onokulufumana ukuvelisa umgangatho ophezulu wemveliso oyifunayo. Ukuba uxinzelelo alusetyenziswanga ngokuchanekileyo kuyo yonke inkqubo, kunokukhokelela kwimibimbi, ikhefu lewebhu, kunye neziphumo ezibi zenkqubo ezifana ne-interleaving (chearing), i-out-of-gauge (ukuprintwa), ubukhulu obungahambelaniyo bokugquma (i-coating), ukuhluka kobude (i-laminating ), i-curling yezinto eziphathekayo ngexesha le-lamination process, kunye ne-spooling defects (ukwelula, ukulinganisa, njl.), Ukukhankanya nje ezimbalwa.
Abavelisi kufuneka bahlangabezane nemfuno ekhulayo yokuvelisa iimveliso ezisemgangathweni ngokufanelekileyo kangangoko. Oku kukhokelela kwimfuno engcono, ukusebenza okuphezulu kunye nemigca yemveliso ephezulu. Ingaba inkqubo iguqula, i-slicing, iprinting, i-laminating okanye nayiphi na enye inkqubo, nganye inento enye into efanayo - ukulawulwa koxinzelelo olufanelekileyo kubangela umgangatho ophezulu, ukuveliswa kweendleko.
Itshathi yoLawulo lweNxibelelwano yeManuwali
Kukho iindlela ezimbini eziphambili zokulawula uxinzelelo, i-manual okanye i-automatic. Kwimeko yolawulo lwencwadi, ingqalelo kunye nobukho bomqhubi buhlala bufuneka ukuze ulawule kwaye ulungelelanise isantya kunye ne-torque kuyo yonke inkqubo. Kulawulo oluzenzekelayo, umqhubi ufuna kuphela ukwenza igalelo ngexesha lokusekwa kokuqala, njengoko umlawuli unoxanduva lokugcina uxinzelelo olufunwayo kuyo yonke inkqubo. Oku kunciphisa intsebenziswano yomsebenzisi kunye nokuxhomekeka. Kwiimveliso zolawulo oluzenzekelayo, ngokuqhelekileyo kukho iindidi ezimbini zeenkqubo, i-loop evulekile kunye nolawulo oluvaliweyo.
