1. Mea waiwai: ke kila kalapona maʻamau (Q hua ikaika), kiʻekiʻe kiʻekiʻe kalapona structural kila (me ka awelika kalapona hapa hakina o 20/10000), alloy structural kila (me ka awelika manganese hapa hapa o ma kahi o 2% i 20Mn2), hoolei kila (ZG230-450 yield point aole emi iho ma mua o 40 i hoʻoheheʻe 'ia ma mua o ka tensiron 230 ole emi iho ma mua o 40 ka ikaika. (HT200 hina hina hao hao tensile ikaika).
2. ʻO nā ʻano hana wela maʻamau: annealing (hoʻoluʻu mālie i ka umu), hoʻomaʻamaʻa maʻamau (hoʻoluʻu i ka ea), hoʻopaʻa (hoʻomaʻalili wikiwiki i ka wai a i ʻole ka aila), hoʻomaʻamaʻa (hoʻomaʻamaʻa hou i ka ʻāpana quenched i kahi mahana ma lalo o ka mahana koʻikoʻi, e paʻa ana i kahi manawa a laila hoʻomaha i ka ea), quenching and tempering (ke kaʻina hana o ka wela kemika + kiʻekiʻe). nitriding, carbonitriding).
3. Hōʻike hemahema o nā mea hoʻopaʻa: haʻihaʻi ma muli o ka lawa ʻole o ka ikaika; ʻO ka elastic nui a i ʻole ka deformation plastic; ʻO ka ʻaʻahu nui, paheʻe, a i ʻole ka wela o ka ʻili o ka friction; Hoʻopili ʻoluʻolu;
4. Hōʻike ʻole ʻia ka luhi: ʻO ka hāʻule ma lalo o ka hana o ke koʻikoʻi hoʻololi i kapa ʻia ʻo fatigue failure. Nā hiʻohiʻona: Haʻi koke ma hope o ka hoʻohana ʻana i kekahi ʻano koʻikoʻi; ʻO ke koʻikoʻi kiʻekiʻe ma lalo o ke koʻikoʻi i ka wā o ka haʻihaʻi ʻoi aku ka haʻahaʻa ma mua o ka palena o nā mea; ʻOiai no nā mea plastik, ʻaʻohe deformation plastic nui i ka wā e haki ai. I ka hoʻoholo ʻana i ka palena luhi, pono e noʻonoʻo ʻia ka nui o ke koʻikoʻi, ka helu o nā pōʻai, a me nā ʻano pōʻai.
5. Nāʻano o nā kaula: nā kaula maʻamau, nā paipu paipu, nā'āpana'āpana, nā kaula trapezoidal, nā kaula serrated.
6. Nā ʻano kumu kumu o nā pili wili: nā hoʻokuʻi paʻa (nā hoʻopili bolted maʻamau, nā hoʻopili bolted me nā puka hili), nā hoʻokuʻi poʻo ʻelua, nā hoʻopili wili, a me nā pilina paʻa.
7. Anti loosening of threaded connections: friction anti loosening (spring washer, double nut, elliptical self-locking nut, transverse cut nut), mechanical anti loosening (open pine and groove nut, stop washer, round nut stop washer, serial steel wire), mau anti loosening (punching method, end welding method, bonding method).
8. Nā ala e hoʻomaikaʻi ai i ka ikaika o nā hoʻopili bolt: pale i ka hana ʻana i ke koʻikoʻi piko; E ho'ēmi i ka manaʻo kaumaha.
9. Ka 'ike 'ike ma hope o ka ho'oma'ama'a wela: 'O nā puka kiko'ī (ma o nā puka) ma hope o ke kinai 'ana, koi 'ia ka hana 'oki uea; Pono nā puka makapō i ka mīkini ʻala ma mua o ke kinai ʻana a me ka mīkini pololei ma hope o ke kinai ʻana. Hiki ke hana ʻia nā puka kikoʻī ʻole ma mua o ke kinai ʻana (e waiho ana i kahi haʻawina kinai o 0.2mm ma kekahi ʻaoʻao). ʻO ka haʻahaʻa haʻahaʻa loa no ka mīkini paʻakikī o nā ʻāpana kinai ʻia he 0.4mm, a ʻo ka ʻae ʻana no ka hana ʻino ʻana o nā ʻāpana i hoʻopau ʻole ʻia he 0.2mm. ʻO ka mānoanoa o ka uhi ʻana he 0.005-0.008mm, a pono e hana ʻia e like me nā ana pre plating.
10. ʻO nā koi hana mechanical no nā bolts maʻamau o ka papa like ʻoi aku ka kiʻekiʻe ma mua o nā bolts ikaika kiʻekiʻe, akā ʻo nā bols ikaika kiʻekiʻe he koi ʻae hou aku no ka ikehu hopena i hoʻohālikelike ʻia me nā bolts maʻamau. ʻO ka ikaika o nā bolts kiʻekiʻe ʻaʻole ia i loko o kā lākou mea i hoʻolālā ʻia, akā i ka paʻakikī kiʻekiʻe, ka hana palekana kiʻekiʻe, a me ke kūpaʻa ikaika i ka pōʻino o kā lākou mau nodes i hoʻolālā ʻia. ʻO ke kumu o kona ikaika kiʻekiʻe ʻo ia i ka wā o ka hana maʻamau, ʻaʻole ʻae ʻia ka node e hana i kekahi paheʻe pili, ʻo ia hoʻi, he liʻiliʻi ka deformation elastic-plastic a he kiʻekiʻe ka node stiffness. ʻO ka ʻokoʻa nui ma waena o nā bolts kiʻekiʻe a me nā bolts maʻamau, ʻaʻole ia ka ikaika o ka mea i hoʻohana ʻia, akā ke ʻano o ka ikaika i hoʻohana ʻia. ʻO ke kumu, ʻo ia ka hoʻohana ʻana i ka ikaika pretension a hoʻohana i ka ikaika friction static e pale aku i ka ʻā.
