Nibihe byiciro byibyuma byubatswe

Imiterere y'ibyuma ikoreshwa bizaba bitandukanye ukurikije imbaraga zo gukoresha ahantu hatandukanye nabyo biratandukanye, none nigute ushobora gusuzuma urwego rwimbaraga?
Imiterere yicyuma ihindura imbaraga urwego:
Urwego rwimbaraga zibyuma byubatswe kugirango bihuze ibyuma ni 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, nibindi. nominal tensile imbaraga agaciro nigipimo cyimiterere yibyuma byubaka ibikoresho.
Kurugero, ibyuma byubatswe mubyiciro 4.6.Igisobanuro ni:
1, ibyuma byubatswe bya bolt ibikoresho nominal umusaruro imbaraga za 400 × 0,6 = 240MPa urwego rwo gukora urwego 10.9 imbaraga zikomeye ibyuma byubaka.
2. Ikigereranyo cyimbaraga zo guhuza ibyuma byubatswe ni 0,6;
3, imiterere yicyuma bolt material nominal tensile imbaraga zigera kuri 400MPa;
Nyuma yo kuvura ubushyuhe, ibikoresho birashobora kugeraho:
1, ibyuma byubatswe bya bolt ibikoresho nominal umusaruro wimbaraga za 1000 × 0.9 = 900MPa urwego
2. Ikigereranyo cyingufu zingufu zicyuma cyubatswe ni 0.9;
3, ibyuma byubaka bolt material nominal tensile imbaraga za 1000MPa;
Ubusobanuro bwibyuma byubatswe bya bolt ubukana bwurwego ni urwego mpuzamahanga, imiterere yicyuma cya bolt yo murwego rumwe rwimikorere, ntakibazo cyarwo ndetse no gutandukanya agace kabyara umusaruro, imikorere yacyo ni kimwe, hitamo amanota yimikorere gusa kubishushanyo mbonera.
Imbaraga zo mu cyiciro cya 8.8 na 10.9 zerekeza ku gipimo cyoguhangayikishwa nicyuma cyubaka ibyuma 8.8GPa na 10.9 GPa
8.8 Nominal tensile imbaraga 800N / MM2 Imbaraga zitanga izina 640N / MM2
Imiterere rusange yibyuma byerekanwa na "XY", X * 100 = imbaraga zingutu zububiko bwibyuma, X * 100 * (Y / 10) = imbaraga zumusaruro wibyuma byubatswe (nkuko biteganijwe muri label: umusaruro imbaraga / tensile imbaraga = Y / 10), nka 4.8, imbaraga zingana zububiko bwibyuma ni: 400MPa, umusaruro utanga: 400 * 8/10 = 320MPa.
Ibyavuzwe haruguru nimbaraga zicyuma cyubaka ibyuma, turimo dukoresha dukurikije urwego rutandukanye rwo gukoresha, munzu yakoreshejwe muri rusange imbaraga zo murwego rwo hejuru.
