I-angle ye-R yetyhubhu yesikwere ichazwe njani kumgangatho wesizwe?

I-angle ye-R kwityhubhu yesikwere yi-arc yenguqu ekudibaneni kweenqwelo-moya ezimbini, ngokuqhelekileyo isiqingatha sedayamitha yomgca osembindini we-arc R egobileyo. Ixabiso le-arc egobileyo ye-R ngokuqhelekileyo yi-1.5 ~ 2.0 amaxesha obubanzi bombhobho. Ubungakanani be-angle ye-R bunqunywe ngokuhambelana nobukhulu bodonga lwetyhubhu yesikwere. I-angle ye-R ihlulwe kwi-angle yangaphakathi ye-R kunye ne-angle ye-R yangaphandle. I-R yangaphakathi ngokuqhelekileyo i-1.5 ~ 2 amaxesha ubukhulu bodonga. Iityhubhu zetsimbi zesikwere ezineengile ezahlukeneyo ze-R nazo zinokuveliswa ngokweemfuno zomsebenzisi.
Umzekelo, kumbhobho wentsimbi oxande one-arc R ejikelezayo, A=1.0MM, idiagonal=1.15MM, uyazi njani i-engile engu-R? Ukuba ngumbhobho wentsimbi yesikwele kunye ne-arc, ngaba indlela yokubala iyafana? Uxande unobude be-A kunye nobubanzi be-B, i-diagonal ye-C, kunye ne-radius yeekona ezine ze-arcs R iyalingana. Bala ubungakanani be-R ngale fomula ilandelayo: (C/2-R) ^ 2=(A/2-R) ^ 2+(B/2-R) ^ 2 C ^ 2/4-CR+R ^ 2 =A ^ 2/4-AR+R ^ 2+B ^ 2/4-BR+R ^ 2 4R ^ 2-4 (A+BC) R+(A ^ 2+B ^ 2-C ^ 2)=0 .
Kufuneka kugxininiswe apha ukuba i-R angle ye-tube ephantsi ye-rectangular ayibhekiseli kwi-arc, kodwa i-angle yeziko. I-arc ibhekisela kwisahlulo kwi-circumference, kunye ne-angle edibeneyo yomgca phakathi kweziphelo ezimbini ze-arc kunye neziko yi-angle yeziko. Ekubeni i-engile yesangqa i-2 π R kunye ne-engile ephakathi ehambelana nayo yi-2 π, ubude be-arc obuhambelana neyunithi yeziko le-engile ngu-2 π R/2 π=R. Ngoko ke, ubude be-arc obuhambelana nayo nayiphi na i-engile esembindini a (iyunithi yeradian)=aR ifunyenwe. Iindlela zokulinganisa kunye nezixhobo ze-square tube R angle ziquka i-R gauge kunye neprojekti. Igeyiji ye-R ingasetyenziselwa amanqaku ashinyeneyo, iprojektha yamanqaku amahle, kunye neCMM yeemfuno eziphezulu.
