Ndeapi mamakisi emabhaudhi esimbi

Simbi chimiro bhoti mukushandiswa ichave yakasiyana maererano nesimba rekushandiswa kwakasiyana kwenzvimbo kwakasiyanawo, saka sei kutonga giredhi resimba?
Simbi chimiro mabhoti giredhi resimba:
Simbi giredhi resimbi chimiro bhoti yesimbi chimiro chekubatanidza ndeye 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc. Iyo giredhi resimba resimbi chimiro bhoti rine zvikamu zviviri zvenhamba, izvo zvinomiririra nominal tensile simba kukosha uye flexion ratio yesimbi chimiro bhaudhi zvinhu.
Semuenzaniso, mabhaudhi esimbi egiredhi 4.6.Zvinoreva izvi:
1, simbi chimiro bhaudhi zvinhu zita goho simba re400 × 0.6 = 240MPa giredhi rekuita giredhi 10.9 yakakwirira simba simbi chimiro bhaudhi.
2. The compressive simba reshiyo yesimbi chimiro bolt zvinhu 0.6;
3, simbi chimiro bhaudhi zvinhu nominal tensile simba kusvika 400MPa;
Mushure mekupisa kurapwa, zvinhu zvinogona kubudirira:
1, simbi dhizaini bhaudhi zvinhu zita goho simba re1000 × 0.9 = 900MPa giredhi
2. Chiyero chekusimbisa simba resimbi chimiro bhoti ndeye 0.9;
3, simbi dhizaini bhaudhi zvinhu nominal tensile simba re1000MPa;
Chirevo chesimbi chimiro bhoti intensity giredhi ndiyo yepasirese mwero, iyo simbi dhizaini bhaudhi yegiredhi rekuita giredhi, zvisinei nechinhu chayo uye musiyano wenzvimbo yekugadzira, kuita kwayo kwakafanana, sarudza giredhi rekuita chete pachigadziko chekugadzira.
Iwo magiredhi esimba 8.8 uye 10.9 anoreva shear stress mamakisi emabhaudhi esimbi 8.8GPa uye 10.9 GPa.
8.8 Nominal tensile simba 800N/MM2 Nominal goho simba 640N/MM2
General simbi chimiro bhaudhi inoratidzwa ne "XY", X * 100 = simba rekusimba resimbi chimiro bhaudhi, X * 100 * (Y / 10) = simba regoho resimbi yechimiro bhaudhi (sezviri kutaurwa mune iyo label: goho simba / kusimba simba = Y / 10), yakadai se4.8, simba rekusimba resimbi yekugadzirwa kwesimbi ndeye: 400MPa, goho simba: 400 * 8/10 = 320MPa.
Iri pamusoro ndiro giredhi resimba resimbi yekugadzira bhaudhi, isu tiri kushandiswa zvinoenderana negiredhi rakasiyana rekushandisa, muchivako chinoshandiswa chinowanzo yakakwirira simba giredhi bhaudhi.
