Ogo arụmọrụ Bolt

Bolt arụmọrụ ọkwa, ya bụ bolt arụmọrụ ọkwa maka ígwè Ọdịdị njikọ, na-ekewa n'ime ihe karịrị 10 akara ule, dị ka 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc.Bolt arụmọrụ ọkwa labelụ mejupụtara nke. akụkụ abụọ, nke n'otu n'otu na-anọchi anya uru ike tensile ọnụ ala yana oke ike ịgbagọ nke ihe bolt.

Ihe ọkwa ọkwa bolt pụtara bụ ọkọlọtọ mba ụwa niile, bolt nke otu ọkwa arụmọrụ, n'agbanyeghị ọdịiche nke ihe ya na mmalite ya, arụmọrụ ya bụ otu, imewe nwere ike họrọ naanị ọkwa arụmọrụ.

Ike ọkwa 8.8 na 10.9 ịdị ukwuu na-ezo aka n'ogo nke ịkpacha nrụgide nke bolt bụ 8.8 GPa na 10.9 GPa 8.8 nominal tensile ike nke 800 n / 640 n bụ nominal mkpụrụ ike bolts / bụ n'ozuzu na-egosipụta na "XY" ike, X * 100 = ike ike nke bolt, X * 100 * (Y / 10) = ike ike nke bolt (dị ka ekwuru na logo: ike mkpụrụ / ike = Y / 10, ya bụ 0. Y gosiri) dị ka ịdị ukwuu 4.8, ike tensile nke bolt bụ: 400 mpa.Ike ike: 400 * 8/10 = 320MPa. Ọzọ: igwe anaghị agba nchara bolts na-na-na-na-akara A4-70, ọdịdị nke A2-70, nke pụtara ma kọwaa nha: ogologo nha unit. N'ụwa taa, e nwere isi ihe abụọ dị iche iche, otu maka metric usoro, ihe unit bụ mita (m), centimeters (cm), mm (mm), wdg, na Europe, China na Japan na ndị ọzọ n'ebe ndịda ọwụwa anyanwụ Asia ojiji bụ. ọzọ, ọzọ bụ English, na-atụ unit bụ tumadi maka sentimita (inch), ọtụtụ-eji na United States, Britain na ndị ọzọ European na A.mba merika.1.Ntụ usoro metrik: 1m = 100 cm = 1000 mm2, nha usoro Bekee: (8) 1 inch = 8 ints 1 inch = 25.4 mm

Bolts eji maka njikọ nke ígwè owuwu nwere ihe karịrị 10 akara ule, gụnyere 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 na 12.9.Bolt arụmọrụ ọkwa labelụ mejupụtara abụọ akụkụ, nke karị na-anọchi anya ọnụ tensile ike uru na Ehulata ike ruru nke ihe bolt. Dịka ọmụmaatụ: bolts nwere ogo arụmọrụ 4.6, nke pụtara:
1. The nominal tensile ike nke bolt ihe ruru 400MPa;
2. Oke ike na-ehulata nke ihe mkpuchi bụ 0,6;
3. The nominal mkpụrụ ike nke bolt ihe ruru 400 × 0.6 = 240MPa klas
Performance ọkwa 10.9 elu ike bolt, ya ihe onwunwe mgbe okpomọkụ ọgwụgwọ, nwere ike nweta:
1. The nominal tensile ike nke bolt ihe ruru 1000MPa;
2. Oke ike na-ehulata nke ihe mkpuchi bụ 0,9;
3. The nominal mkpụrụ ike nke bolt ihe ruru 1000 × 0.9 = 900MPa klas
