Sezvatinoziva tese,chikamu chesimbi chine mhangochinhu chinowanzo shandiswa pakuvaka zvivakwa zvesimbi. Unoziva here kuti zvikamu zvingani zvezvikamu zvezvivakwa zvesimbi refu? Ngatitarisei nhasi.
1, nhengo yakamanikidzwa zvakanyanya
Nhengo yekubata simba re axial inonyanya kureva nhengo ine axial tension kana axial pressure, inova ndiyo iri nyore pakati penhengo.
2, nhengo yeFlexural
Nhengo dzinokombama dzinonyanya kukanganiswa nekukombama uye masimba anochinjika, mazhinji acho ari matanda. Chimiro chechikamu chenhengo iyi chakaita seI. Kunewo groove, trapezoid uye Z-shape kana simba riri diki. Kana simba riri guru, chimiro chebhokisi chinogona kushandiswa. Zvinofanira kucherechedzwa kuti pakuverenga simba rechimiro chenhengo dzakadaro, kwete simba rekukombama chete, asiwo simba rekuchekwa uye kugadzikana zvinofanirwa kuverengerwa.
3, nhengo yakatakura zvinhu zvakasiyana-siyana
Nhengo dzine stress dzakasimba kazhinji hadzingotambudziki nesimba re axial chete, asiwo ne bend moment uye transverse shear force. Nhengo dzine stress dzakasimba kazhinji dzine mhando mbiri dzezvikamu zvakaita se cross uye I-shaped sections. Kana mutoro wacho wakakura, nhengo dzine tubular uye box shaped dzinogona kushandiswawo. Nhengo dzine stress dzakasimba dzine mafomu akawanda ezvikamu, uye kuverenga kwacho kwakaoma kupfuura nhengo mbiri dzekutanga, kureva kuti, kuverenga simba, asiwo kutarisa kugadzikana.
Zvikamu zvikuru zvezvivakwa zvesimbi refu matanda nemakoramu. Zviri pachena kuti mafomu ezvikamu zvematanda nemakoramu anosiyanawo zvikuru, uye kune mhando dzakasiyana-siyana. Kunyangwe mafomu ezvikamu achisiyana zvikuru, akafanana mumisimboti yekugadzira. Chimiro chechikamu chedanda chinogumira kuchimiro cheI nechimiro chebhokisi. Chimiro chechikamu chechikamu chekoramu chinogona kukamurwa kuita zvikamu zviviri, chimwe chikamu chakasimba, kureva chimiro cheI nechimiro chemuchinjikwa. Chimwe chikamu chisina chinhu, kureva chimiro chetubular nebhokisi.
Kubva pakuona kwekugadzira, mune dzimwe nguva, nhengo dzakagadzirwa nesimbi imwe chete hadzigone kuzadzisa zvinodiwa zvekugadzira. Saka, zvinodikanwa kushandisa imwe fomu, kureva, fomu yechikamu chakabatanidzwa. Kune chikamu chakabatanidzwa, chinongogumira kuchikamu chakabatanidzwa chakasungirirwa zvichienderana nekuvandudzwa kwechimiro chazvino. Zvikamu zvakabatanidzwa zvinogona kukamurwa kuita zvikamu zviviri, chimwe chikamu chakagadzirwa nesimbi yechikamu, uye chimwe chikamu chakabatanidzwa chakagadzirwa nesimbi yechikamu nesimbi yesimbi kana chakagadzirwa nesimbi yesimbi zvachose. Muchimiro chewelding, chikamu chakabatanidzwa chakagadzirwa nemaplate esimbi chete chine kuchinjika kukuru. Kune vagadziri, zviri nyore kwazvo kusarudza chikamu ichi chakabatanidzwa, kungave chiri chiyero chekunze kana chimiro chechikamu chechikamu. Kushandiswa kwakanyanya kwetekinoroji yewelding otomatiki mumakore achangopfuura kwakagadzirawo mamiriro akanaka kune akawanda macompound components anoshandisa chimiro chechikamu chekuronga welding.
Isu tiri vagadziri vakuru vema "hollow section" muChina. Tinonyanya kugadzira zvinhu zvakagadzirwa zvinoenderana nezvinodiwa nevanhu:chikamu cheyuantai chine mhango checrane, yuantai ERW chubhu, yuantai LSAW chubhu, chubhu yeYuantai SSAW, yuantai HFW chubhu, chubhu isina musono yeyuantai.
