I-Benkelman Deflection Beam / Beckman Deflection Instrument

Benkelman deflection beam/Beckman isixhobo sokuphambuka

Indlela yeBeckman beam yindlela efanelekileyo yokulinganisa ixabiso le-elastic deflection yomgangatho wendlela phantsi kokulayisha okumileyo okanye ukulayisha okucothayo kakhulu, kwaye inokubonisa kakuhle amandla onke omgangatho wendlela.

1) Amalungiselelo phambi kovavanyo

(1) Khangela kwaye ugcine isithuthi esisemgangathweni sokulinganisa sikwimeko efanelekileyo kunye nokusebenza kwe-braking, kunye netyhubhu yangaphakathi yetayara ihlangabezana noxinzelelo oluchaziweyo lokunyuka kwamaxabiso.

(2) Layisha (iibhloko zentsimbi okanye iaggregates) kwitanki yemoto, kwaye ulinganise ubunzima bubonke be-asi yangasemva kunye nebhalansi yomhlaba, ehlangabezana nemimiselo yomthwalo we-asi efunekayo.Umthwalo we-asi akufuneki utshintshwe ngexesha lokuqhuba kunye nomlinganiselo wemoto.

(3) Ukulinganisa indawo yokudibanisa itayara;sebenzisa ujeke ukukrazula i-asi yangasemva yemoto kwindlela ethe tyaba kwaye egudileyo eqinileyo, sasaza iphepha elitsha lekhabhoni phantsi kwetayara, kwaye ngobunono uwise ijekhi ukuprinta amanqaku etayara kwiphepha legrafu, Sebenzisa iplanometer okanye indlela yokubala yesikwere. ukulinganisa indawo yokudibanisa itayara, ichanekile ukuya kwi-0.1cm2.

(4) Jonga uvakalelo lwesalathisi sokudayela kwegeyiji yokuphambuka.

(5) Xa ulinganisa kwipavumente ye asphalt, sebenzisa ithemometha yomphezulu wendlela ukulinganisa iqondo lobushushu kunye nobushushu bomphezulu wendlela ngexesha lovavanyo (iqondo lobushushu liyatshintsha imini yonke kwaye kufuneka lilinganiswe nangaliphi na ixesha), kwaye ufumane ubushushu obuphakathi koludlulileyo. Iintsuku ezi-5 (ubushushu obuphezulu bemihla ngemihla kunye nobushushu obuncinci bemihla ngemihla) kwisikhululo semozulu.Ubushushu obuphakathi).

(6) Rekhoda izixhobo, ulwakhiwo, ubukhulu, ulwakhiwo kunye nokugcinwa kwepavemente ye-asphalt ngexesha lokwakha okanye ulwakhiwo.

2) Amanyathelo ovavanyo

(1) Lungiselela amanqaku okulinganisa kwicandelo lovavanyo, umgama oxhomekeke kwiimfuno zovavanyo.Amanqaku okulinganisa kufuneka abe kwibhanti lomkhondo wevili lomzila wendlela kwaye ziphawulwe ngepeyinti emhlophe okanye itshokhwe.(2) Lungelelanisa umsantsa wevili elingasemva lesithuthi sovavanyo kwindawo emalunga ne-3 ~ 5cm emva kwendawo yokulinganisa.

(3) Faka igeyiji yokuphambuka kwisithuba esiphakathi kwamavili angasemva emoto, ngokuhambelana necala lemoto, ingalo yomqadi mayingalichukumisi itayara, kunye negeyiji yokuphambuko ibekwe kwindawo yokulinganisa (3 ~ 5cm). Phambi kombindi wesikhewu sevili), kwaye faka isalathisi sokucofa kwintonga yokulinganisa yegeyiji yokujikela, lungisa igeyiji yokucofa iye ku-zero, cofa igeyiji yokuphambuka kancinci ngomnwe wakho, kwaye ujonge ukuba igeyiji yokucofa ibuyela ku-zero. ngokuzinzileyo.Imitha yokuphambuka inokulinganiswa kwicala elinye okanye kumacala omabini ngexesha elinye.(4) Umhloli uvuthela impempe ukuyalela imoto ukuba iqhubele phambili ngokukhawuleza, kwaye isalathisi sokudayela siyaqhubeka sijikeleza phambili njengoko ukuguqulwa komphezulu wendlela kwanda.Xa izandla zokubukela zihamba kwixabiso eliphezulu, funda ngokukhawuleza ukufunda kokuqala kwe-L1.Imoto isahamba phambili, kwaye isandla sijikela kwicala elichaseneyo: Emva kokuba imoto iqhube iphuma kwiradiyasi ephambukayo (ngaphezu kwe-3m), vuthela impempe okanye uphakamise iflegi ebomvu ukuyalela ukuma.Funda ukufundwa kokugqibela kwe-L2 emva kokuba izandla zewotshi zijikeleze ngokuzinzileyo.Isantya sangaphambili semoto kufuneka sibe malunga ne-5km/h.
