helu hoʻokō Bolt

ʻO ka papa hana Bolt, ʻo ia hoʻi ka papa hana bolt no ka hoʻohui ʻana i ke kila, ua māhele ʻia i ʻoi aku ma mua o 10 mau māka, e like me 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc. ʻelua ʻāpana, e hōʻike ana i ka waiwai o ka ikaika tensile nominal a me ka lakene ikaika kulou o nā mea bolt.

ʻO ke ʻano o ka papa hana bolt ka pae honua ākea, ka bolt o ka papa hana like, me ka nānā ʻole i ka ʻokoʻa o kāna mea a me ke kumu, ua like kāna hana, hiki i ka hoʻolālā ke koho wale i ka pae hana.

ʻO ka nui o ka ikaika 8.8 a me 10.9 magnitude e pili ana i ke kiʻekiʻe o ke koʻikoʻi koʻikoʻi o ka bolt he 8.8 GPa a me 10.9 GPa 8.8 ka ikaika tensile nominal o 800 n / 640 n ka mea i hōʻike ʻia ma ka "XY" ikaika, X * 100 = ka ikaika tensile bolt, X * 100 * (Y / 10) = ka ikaika hua o ka bolt (e like me ka mea i ʻōlelo ʻia ma ka logo: ka yield/tensile strength = Y / 10, ʻo ia hoʻi 0. Hōʻike ʻo Y) e like me ka nui 4.8, ʻO ka ikaika tensile o ka bolt: 400 mpa. Ka ikaika hua: 400 * 8/10 = 320MPa. i ka honua i kēia mau lā ʻelua mau ʻano nui, hoʻokahi no ka ʻōnaehana metric, ʻo ka ʻāpana ana he mika (m), kenimika (cm), mm (mm), etc. ʻoi aku, ʻo kekahi ʻo English, ʻo ke ana ʻana ka mea nui no nā iniha (inihi), hoʻohana nui ʻia ma ʻAmelika Hui Pū ʻIa, Pelekane a me nā ʻāina ʻEulopa a me ʻAmelika.1. Ana ʻōnaehana metric: 1m =100 cm=1000 mm2, ana ʻōnaehana English: (8) 1 ʻīniha =8 ints 1 ʻīniha =25.4 mm

ʻO nā bolts i hoʻohana ʻia no ka hoʻopili ʻana i nā hale kila i ʻoi aku ma mua o 10 mau māka, me ka 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 a me 12.9. ʻO ka lepili papa hana Bolt he ʻelua mau ʻāpana, e hōʻike ana i ka waiwai ikaika tensile nominal a ʻO ka lakio ikaika o ka piko o ka mea bolt. No ka laʻana: nā bolts me ka helu hana 4.6, ʻo ia hoʻi:
1. ʻO ka ikaika tensile nominal o nā mea bolt hiki i 400MPa;
2. He 0.6 ka lakene ikaika kulou o ka mea bolt;
3. Hiki i ka 400 × 0.6 = 240MPa ka ikaika o ka hoʻoulu ʻana o ka mea bolt.
ʻO ka papa hana 10.9 kiʻekiʻe ikaika bolt, kāna mea ma hope o ka mālama wela, hiki ke hoʻokō:
1. ʻO ka ikaika tensile nominal o ka mea bolt hiki i 1000MPa;
2. He 0.9 ka lakene ikaika kulou o ka mea bolt;
3. Hiki i ka 1000 × 0.9 = 900MPa ka nui o ka ikaika hāʻawi inoa o nā mea bolt.
