Isixazululo Sokulawula I-Tension
Bheka eduze kwakho, imikhiqizo eminingi oyibonayo futhi oyisebenzisayo yenziwa kusetshenziswa uhlobo oluthile lokulawulwa kwengxabano. Ukusuka kwiphakheji yokusanhlamvu ekuseni kuya kwilebuli ebhodleleni lamanzi, nomaphi lapho uya khona izinto ezincike ekulawulweni kwengxabano eqondile enqubweni yokukhiqiza. Izinkampani ezizungeze umhlaba ziyazi ukuthi ukulawulwa kwengxabano efanelekile "yenza noma iphule" kulezi zinqubo zokukhiqiza. Kodwa kungani? Kuyini Ukulawulwa Kwengxabano futhi Kungani Kubaluleke Kangaka Ezokukhiqiza?
Ngaphambi kokuthi singeneleUkulawula ukungezwani, kufanele siqale siqonde ukuthi yikuphi ukungezwani okukhona. Ukungezwani ngamandla noma ukungezwani okusetshenziselwa izinto ezikubangela ukwelula indlela yamandla asetshenzisiwe. Ezokukhiqiza, lokhu kuvame ukuqala lapho impahla eluhlaza idonswa kwinqubo ngephuzu lesenzo eliphansi. Sichaza ukungezwani njengoba i-torque isetshenziswa enkabeni yombuso, ihlukaniswe yi-roll radius. Ukungezwani = i-torque / radius (t = tq / r). Lapho ukungezwani kuphezulu kakhulu, ukungezwani okungafanele kungadala lokho kudalule futhi kubhubhise ukwakheka komqulu, noma kulimaze umqulu uma ukungezwani kudlula amandla enqamula. Ngakolunye uhlangothi, ukungezwani okuningi kungalimaza nomkhiqizo wakho wokugcina. Ukungezwani okunganele kungadala ukuthi i-reel-up reel yelule noma i-SAG, ekugcineni okuholela kumkhiqizo ompofu ophelile.
Ukulingana kwe-tension
Ukuze siqonde ukulawulwa kwengxabano, kudingeka siqonde ukuthi "iWebhu" iyini. Leli gama libhekisela kunoma iyiphi impahla edluliswa ngokuqhubekayo kusuka ku-roll of paper, ipulasitiki, ifilimu, i-filament, izindwangu, intambo noma insimbi. Ukulawulwa kwe-Tension yisenzo sokugcina ukungezwani okufisayo kuwebhu njengoba kudingwa yilokho okufunwayo. Lokhu kusho ukuthi ukungezwani kulinganiswa futhi kugcinwe endaweni ebekiwe yokusetha ukuze iwebhu igijime kahle kuyo yonke inqubo yokukhiqiza. Ukungezwani kuvame ukulinganiswa kusetshenziswa uhlelo lokulinganisa lwe-Imperial ngamaphawundi ngakolunye uhlangothi (Pli) noma ama-metric kumaNewtons Per Centrimeter (N / cm).
Ukulawulwa kwengxabano efanelekile kwenzelwe ukulawula ngokunembile ukungezwani kwiWebhu, ngakho-ke kufanele kulawulwe ngokucophelela futhi kugcinwe kuzinga eliphansi kuyo yonke inqubo. Umthetho wesithupha ukusebenzisa inani elincane kakhulu lokungezwani ongathola ukukhiqiza umkhiqizo osezingeni eliphakeme owufunayo. Uma ukungezwani kungasebenzi ngokunembile kuyo yonke inqubo, kungaholela emibini, amakhefu wewebhu, kanye nemiphumela yenqubo engeyinhle njengokuhlasela (ukuphrinta), ukuhlukahluka okungahambelani (ukuhambisa phansi ), Ukugcotshwa kokuqukethwe ngesikhathi senqubo yokukhanyisela, kanye nokuphazamiseka okukhohlisayo (ukwelula, inkanyezi, njll.), ukumane nje kube namagama ambalwa.
Abakhiqizi badinga ukufeza isidingo esikhulayo ukukhiqiza imikhiqizo esezingeni elifanele ngangokunokwenzeka. Lokhu kuholela esidlweni sokusebenza okungcono, okuphezulu kanye nemigqa yokukhiqiza esezingeni eliphakeme. Ukuthi inqubo iguqulwa, isilayidi, ukuphrinta, ukugcona noma iyiphi enye inqubo, ngalinye linento eyodwa evamile - imiphumela efanelekile yokulawula ukungezwani.
Ishadi lokulawula ukungezwani
Kunezindlela ezimbili eziyinhloko zokulawula ukungezwani, ibhukwana noma okuzenzakalelayo. Endabeni yokulawulwa kwesandla, ukunakwa kanye nokuba khona kwe-opharetha kuhlale kudingeka ukuze kusetshenziswe futhi kulungiswe isivinini ne-torque kuyo yonke inqubo. Ekulweni okuzenzakalelayo, opharetha kuphela udinga ukwenza okokufaka ngesikhathi sokusetha kokuqala, njengoba isilawuli sinesibopho sokugcina ukungezwani okufisayo inqubo yonke. Lokhu kunciphisa ukuxhumana kwe-opharetha kanye nokuncika. Emikhiqizweni yokulawula ezenzakalelayo, kuvame ukuba nezinhlobo ezimbili zezinhlelo, i-open loop kanye nokulawulwa kwe-loop evaliwe.
