Ko angle yeR yechubhu yemativi mana inotsanangurwa sei muchiyero chenyika?

Kona yeR iri mu square tube ndiyo arc inochinja panosangana mapuraneti maviri, iyo inowanzova hafu yedhayamita yemutsetse wepakati we curved arc R angle. Kukosha kwe curved arc R kazhinji kunowanzova 1.5 ~ 2.0 yakapetwa dhayamita yepombi. Saizi ye R angle inotsanangurwa zvichienderana neukobvu hwemadziro e square tube. Kona yeR yakakamurwa kuita angle yemukati yeR uye angle yekunze yeR. R yemukati inowanzova 1.5 ~ 2 yakapetwa ukobvu hwemadziro. Machubhu esimbi ane square steel ane angle dzakasiyana dzeR anogonawo kugadzirwa zvichienderana nezvinodiwa nemushandisi.
Semuenzaniso, papombi yesimbi ine rectangular ine arc yakatenderera R, A=1.0MM, diagonal=1.15MM, unoziva sei R angle? Kana iri pombi yesimbi ine arc yakaenzana, nzira yekuverenga yakafanana here? Rectangle ine urefu hweA uye upamhi hweB, diagonal yeC, uye radius yemakona mana R yakaenzana. Verenga saizi yeR uchishandisa fomura inotevera: (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.
Zvinofanira kusimbiswa pano kuti kona yeR yechubhu rezasi rectangular hairevi arc, asi kona yepakati. Arc inoreva chikamu chiri padenderedzwa, uye kona yakabatanidzwa yemutsetse uri pakati pemigumo miviri yearc nepakati ndiyo kona yepakati. Sezvo denderedzwa redenderedzwa riri 2 π R uye kona yepakati inoenderana naro iri 2 π, kureba kwearc kunoenderana nekona yepakati yeyuniti i2 π R/2 π=R. Naizvozvo, kureba kwearc kunoenderana nechero kona yepakati a (radian unit)=aR kunowanikwa. Nzira dzekuyera nezvishandiso zvechubhu repakati R angle zvinosanganisira R gauge neprojekita. R gauge inogona kushandiswa kune mapoinzi akakora, purojekita yepoinzi dzakatetepa, uye CMM kune zvinodiwa zvakanyanya.
