Ukuhlaziywa kwendlela yokuhlola amandla usimende

1. Ukulungiswa kwesifanekiso

1. Ukulungiswa kodaka: hlanganisa u-450±2g kasimende, u-1350±5g wesihlabathi esijwayelekile, kanye no-225±1g wamanzi ku-mixer yokuxuba udaka ngomshini. Faka amanzi ebhodweni kuqala, bese ufaka usimende, ubeke ibhodwe endaweni engaguquki, bese uliphakamisa limile. Bese uqala umshini ngokushesha, ugovuze ngesivinini esiphansi ama-30s, bese wengeza isihlabathi ngokulinganayo ngesikhathi esifanayo lapho kuqala ama-30s amabili. Uma izinga ngalinye lesihlabathi ligcwele kancane, qala ukusuka ezingeni elimahhadlahhadla, bese uhlanganisa inani elidingekayo leleveli ngayinye yesihlabathi ngokushintshana. Guqula umshini ube isivinini esikhulu bese uxuba amanye amasekhondi angu-30. Misa ukuhlanganisa imizuzwana engama-90, bese usebenzisa isikrufu senjoloba ukuklebhula isihlabathi ku-blade kanye nodonga lwebhodwe phakathi kwebhodwe phakathi kwama-.1 15s. Qhubeka ushukumisa ngesivinini esikhulu imizuzwana engu-60.

 

2. Ukwakheka ngokushesha ngemva kokulungiswa kodaka. Lungisa isikhunta esingenalutho sokuhlola kanye nomkhono wesikhunta etafuleni elidlidlizayo, bese usebenzisa isipuni esifanelekile ukuze ulayishe udaka esikhunjini sokuhlola ngezingqimba ezimbili ngokuqondile ebhodweni lokuxuba. Lapho ufaka ungqimba olulodwa, faka udaka olulinganiselwa ku-300g ethangini ngalinye, sebenzisa isipredishithi esikhulu ukuze usakaze iqonde phezulu into engaphezulu komkhono wesikhunta bese ubuyela emuva naphambili eduze kwembobo ngayinye kanye, bese udlidliza izikhathi ezingu-60. Layisha ungqimba lwesibili lodaka futhi, ulusakaze phansi ngesipredishithi esincane, bese usidlidliza futhi izikhathi ezingu-60. Khipha umkhono wesikhunta, susa isikhunta sokuhlola etafuleni elidlidlizayo, sebenzisa irula yensimbi ukuze ubeke irula yensimbi engxenyeni eyodwa ephezulu yesikhunta sokuhlola nge-engeli ecishe ibe ngu-90? Hambisa uhlangothi olulodwa ukuze ukhuhle udaka oludlula ingxenye yesikhunta sokuhlola ngesikhathi, futhi usebenzise irula efanayo ukuze ubushelelezi ubuso bomzimba wokuhlola cishe ngokuvundlile. Maka noma wengeze inothi esikhunjeni sokuhlola ukuze ubonise inombolo yesiqeshana sokuhlola kanye nokuma kwesiqephu sokuhlola esihlobene netafula lokucofa.

3. Bophela isikhunta sokuhlola kanye nefaneli engenalutho phakathi nendawo yetafula elidlidlizayo ngenkathi uhlanganisa udaka. Faka lonke udaka oluxubekile ngokulinganayo kufaneli engenalutho, qala itafula elidlidlizayo, bese udaka lugelezela esikhunjeni sokuhlola ngefaneli. Dlidliza 120s±5s ukuze ume. Ngemuva kokuthi ukudlidliza sekuqediwe, susa isikhunta sokuhlola, sebenzisa irula eliyisicaba ukuze ukhuhle futhi ubushelelezi isihlabathi senjoloba esiphezulu kunesikhunta sokuhlola. Bese umaka isikhunta sokuhlola noma usebenzise inothi ukukhombisa inombolo yesiqeshana sokuhlola.

 

2. Ukulungiswa kwesifanekiso

Susa udaka olusele eduze kwesikhunta, bese ubeka isikhunta sokuhlola eshalofini elivundlile ekamelweni lenkungu noma ibhokisi elimanzi ukuze lilashwe. Umoya omanzi kufanele ukwazi ukuthintana nazo zonke izinhlangothi zesikhunta sokuhlola. Ngesikhathi sokunakekelwa, isikhunta sokuhlola akufanele sibekwe kwezinye isikhunta sokuhlola. Susa i-demold kuze kufike isikhathi esibekiwe sokudiliza, bese umaka isampula ngaphambi kokuyidiliza. Bese ufaka umzimba wokuhlola emanzini angu-20℃±1℃ ukuze welaphe. Uma ibekwe ngokuvundlile, indiza yokuklwebha kufanele ibheke phezulu. Ucezu lokuhlola lubekwe eshalofini elingaboli futhi lugcinwe ibanga elithile phakathi komunye nomunye ukuze kuvunyelwe amanzi ukuthi axhumane nezindawo eziyisithupha zesiqephu sokuhlola. Phakathi nesikhathi sokuphulukisa, isikhawu phakathi kwezibonelo noma ukujula kwamanzi endaweni engaphezulu yesifanekiso akufanele kube ngaphansi kuka-5mm. Ngaphandle kwezifanekiso ezinamahora angama-24 ubudala noma ezibambezeleke ukudilizwa ngo-48h, noma yiziphi izifanekiso esezifinyelele iminyaka yobudala kufanele zikhishwe emanzini imizuzu eyi-15 ngaphambi kokuhlolwa (uhlobo oluphukile). Sula amadiphozithi ebusweni bomzimba wokuhlola bese umboza ngendwangu emanzi kuze kube ukuhlolwa.

 

3. Inqubo yokuhlola

1. Ukunqunywa kwamandla e-flexural

Beka uhlangothi olulodwa lomzimba wokuhlola kusilinda esisekelayo somshini wokuhlola, i-eksisi ende yomzimba wokuhlola i-perpendicular kusilinda esisekelayo, futhi umthwalo usetshenziswa ngokufanayo ohlangothini oluphambene lweprism isilinganiso esingu-50N/s±10N/s ngesilinda sokulayisha. Lize linqamuke. Amandla e-flexural abalwa kanje:

Rf = 1.5FtL/b3

Lapho: I-Ft-umthwalo osetshenziswa phakathi neprism uma yephukile;

L-ibanga phakathi kwamakholomu asekelayo;

B-ubude obuseceleni besikwele sesiqephu se-prism.

2. Ukunqunywa kwamandla okucindezela

Layisha ngokulinganayo ohlangothini lweprism enguhhafu ngenani elingu-2400N/s±200N/s ize inqamuke. Amandla okucindezela abalwa kanje:

Rc = Fc/A

Kufomula: Umthwalo omkhulu we-Fc ngesikhathi sokwehluleka;

A-Indawo yengxenye ecindezelwe.

 

4. Ukuqinisekiswa kwemiphumela yokuhlolwa

1. Thatha inani elimaphakathi lemiphumela yamandla aguquguqukayo eqembu lama-prism amathathu njengomphumela wokuhlolwa. Lapho amanani wamandla amathathu edlula inani elimaphakathi ngo-±10%, inani elimaphakathi kufanele lisuswe bese lithathwa njengomphumela wokuhlolwa wamandla aguquguqukayo;

2. Thatha isilinganiso se-arithmetic samanani alinganiselwe ayisithupha wamandla acindezelayo atholwe kusethi yama-prism amathathu njengomphumela wokuhlola. Uma inani elilodwa kwayisithupha elilinganisiwe lidlula ±10% yenani eliyisilinganiso layisithupha, lo mphumela kufanele uqedwe , Futhi isilinganiso sabahlanu esisele njengemiphumela yokuhlolwa kwamandla acindezelayo. Uma noma yimaphi amanani amahlanu akaliwe edlula ±10% wesilinganiso sawo, le sethi yemiphumela ayivumelekile.

Amandla usimende angasetshenziswa kuphela kumaphrojekthi wokwakha ngemva kokuphasa izivivinyo ezingenhla nokuhlangabezana namazinga. Lokhu kunesibopho sokuphepha kokukhiqiza.
