Menene Darajojin Tsarin Tsarin Karfe

Ƙarfe tsarin kullin da ake amfani da shi zai bambanta bisa ga ƙarfin daban-daban na amfani da wurin kuma ya bambanta, don haka yaya za a yi la'akari da ƙarfin ƙarfin?

Ƙarfe Tsarin Ƙarfe yana da ƙarfin daraja:

Ƙarfin ƙarfin ƙarfe na ƙirar ƙarfe don haɗin tsarin ƙarfe shine 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, da dai sauransu. maras muhimmanci tensile ƙarfi darajar da flexion rabo na karfe tsarin aronji abu.

Misali, karfe tsarin kusoshi na sa 4.6. Ma'anar ita ce:

1, karfe tsarin aron kusa abu maras muhimmanci yawan amfanin ƙasa ƙarfi na 400 × 0.6 = 240MPa sa yi sa 10.9 high ƙarfi karfe tsarin aronji.

2. Ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfe na tsarin ƙarfe na ƙarfe shine 0.6;

3, karfe tsarin aron kusa abu mara kyau tensile ƙarfi har zuwa 400MPa;

Bayan maganin zafi, kayan zai iya cimma:

1, karfe tsarin aron kusa abu maras muhimmanci yawan amfanin ƙasa ƙarfi na 1000 × 0.9 = 900MPa sa

2. The rabo na buckling ƙarfi na karfe tsarin aronji ne 0.9;

3, karfe tsarin aron kusa abu mara kyau tensile ƙarfi na 1000MPa;

Ma'anar ma'anar ƙarfin ƙarfin ƙarfe na tsarin ƙarfe shine ma'auni na duniya, ƙirar ƙirar ƙarfe na ƙimar aiki iri ɗaya, komai kayan sa da kuma bambancin yanki na samarwa, aikin sa iri ɗaya ne, zaɓi ƙimar aiki kawai akan ƙirar ƙira.

Ƙarfin maki 8.8 da 10.9 suna magana ne game da matakan damuwa na ƙarfi na 8.8GPa da 10.9 GPa

8.8 Ƙarfin tensile na ƙima 800N/MM2 Ƙarfin yawan amfanin ƙasa 640N/MM2

Ƙarfin tsarin ƙarfe na gaba ɗaya ana nuna shi ta "XY", X * 100 = Ƙarfin Ƙarfin Ƙarfe na Ƙarfe, X * 100 * (Y / 10) = Ƙarfin Ƙarfin Ƙarfe (kamar yadda aka tsara a cikin lakabin: yawan amfanin ƙasa). Ƙarfin ƙarfi / ƙarfi = Y / 10), kamar 4.8, ƙarfin juzu'i na ƙirar tsarin karfe shine: 400MPa, ƙarfin yawan amfanin ƙasa: 400 * 8/10 = 320MPa.

Abin da ke sama shine ƙarfin ƙarfin ƙarfin tsarin karfe, muna amfani da shi bisa ga nau'in nau'i daban-daban don amfani, a cikin ginin da ake amfani da shi shine gabaɗaya babban ƙarfin ƙarar ƙarfe.
