Dhizaini yekugadzira inoda kuvimba nepunch (yekudhinda) kupa simba, akasiyana kufa saizi, chimiro mhando inoda kusarudza dzakasiyana chibhakera kuti chienzane. Kusarudzwa kunonzwisisika kwepunch kunogona kudzora mutengo uye kuchengetedza zviwanikwa.
Iyo huru chiyero chekufa kusarudzwa chibhakera chinoyerwa ne tonnage, iyo inowanzo kuwanikwa nehuwandu hwekuvhara simba, kugadzira simba, kudzvanya simba uye kubvisa simba. Chikuru iko kuvhara simba.
Simba rekuvhara harina kugadziriswa, uye shanduko yaro mukutsika tsika ndeinotevera: apo chibhakera chinotanga kubata chigadzirwa chekutsika, iro rekuvharisa rinogara riri munzvimbo iri kuwedzera. Kana chibhakera chapinda munenge 1/3 yehukuru hwezvinhu, simba rekuvhara rinosvika pakukosha kwakanyanya. Zvino, nekuda kwekuonekwa kwenzvimbo yekutyoka nzvimbo, simba richadzikira zvishoma nezvishoma. Naizvozvo, kukarukureta kwesimba rekuvharisa ndiko kuverenga simba rekuvhara rakanyanya.

Kukarukureta pamusoro blanking simba
Kukarukureta fomura zvakajairika blanking simba: P = L * t * KS kg
Ongorora: P isimba rinodiwa pakuvhara, mu kg
L ndiyo yakazara mukombero wepakati pechivhariso chechigadzirwa, mm
T ndiyo hukobvu hwezvinhu, mm
KS ishear simba rezvinhu, mu kg / mm 2
Kazhinji, kana chigadzirwa chisina kuvhara chakagadzirwa nesimbi nyoro, kukosha kwakakosha kwesimba rekucheka zvinhu kunotevera: KS = 35kg / mm2
Muenzaniso:
Ngatiti ukobvu hwezvinhu t = 1.2, chinhu chakapfava simbi ndiro, uye chigadzirwa chinoda kubaya ndiro rekona rekona riine chimiro che500mmx700mm. Chii chinonzi kuvhara simba?
Mhinduro: zvinoenderana neyambiro yekuverenga: P = l × t × KS
L = (500 + 700) × 2 = 2400
T = 1.2, Ks = 35Kg / mm²
Naizvozvo, P = 2400 × 1.2 × 35 = 100800kg = 100t
Kana uchisarudza iyo toni, 30% inofanirwa kuwedzerwa pamberi. Naizvozvo, iyo tonnage ingangoita mazana matatu ematani.
