Pākuʻi

1. Mea kumu: e koho pono ʻia ka mea kumu e like me kona ʻano, kaʻina hana, ke kumu kūʻai, ka pūʻulu hana a me ka pōʻai hana,
ʻO nā mea maʻamau:
(1) Ka hao: he maʻalahi ke hoʻolei i nā ʻāpana me ke ʻano paʻakikī;He emi ke kumukuai;Loaʻa i ka hao hoʻolei i ka friction kūloko nui a me ke kūpaʻa haʻalulu maikaʻi.kona
ʻO nā hemahema ka lōʻihi o ka hana ʻana a me ke kumu kūʻai kiʻekiʻe o ka hana ʻāpana hoʻokahi;He maʻalahi ka hoʻoheheʻe ʻana i nā huahana ʻōpala a ʻaʻole maʻalahi ka mālama ʻana i ka maikaʻi;Hāʻawi ʻia ka mīkini ʻana o nā hoʻolei ʻana
Nui, kiʻekiʻe nā kumukūʻai mīkini.
ʻElua ʻano o ka hao hina hina: He kūpono ka HT200 no ka poʻe me ke ʻano maʻalahi a me ke kaomi ʻāpana nui (P > 5kg / cm2)
Alanui alakaʻi, a i ʻole kekahi me ke koʻikoʻi piko nui（ σ 2300kg / cm2) moe, etc.Loaʻa ka HT150 i ka wai maikaʻi akā waiwai mechanical
He kūpono ia no ke kumu me ke ʻano paʻakikī a me ka ukana liʻiliʻi.Inā ʻaʻole hiki i ka hao hina hina ke hoʻokō i nā koi kūpaʻa ʻaʻahu, e ʻae ʻia ke kūpaʻa ʻaʻahu
hao hao.
(2) Ke kila: welded i loko o ke kiʻi me ke kila.ʻOi aku ka nui o ka modulus elastic o ke kila ma mua o ka hao, ʻoi aku ka lahilahi o ka mānoanoa o ka pā o ke kiʻi welded, a ua like kona lakio paona.
ʻO ka rigidity o ke kumu ma kahi o 20% ~ 50% māmā;I ka hihia o kahi ʻāpana liʻiliʻi liʻiliʻi, pōkole ke kaʻina hana a maʻalahi nā mea pono;wiliwili
ʻO ka hemahema o ka hoʻohui ʻana, ʻo ia ka maikaʻi o ka hana anti vibration o ke kila, a pono e lawe ʻia nā ana anti vibration i ka hale;ʻO ka hana nui o ka mea hana;nuipa? iecaianoaaiiuo
He kiʻekiʻe ke kumukūʻai.
