Zvakawanda sei zvaunoziva nezve mechanical dhizaini?
Mechanical dhizaini ibazi reinjiniya iro rinoshandisa misimboti uye matekiniki akasiyana kugadzira, kuongorora uye kukwenenzvera masystem masisitimu uye zvikamu. Mechanical dhizaini inosanganisira kunzwisisa chinangwa chakanangwa chechikamu kana sisitimu, kusarudza zvinhu zvakakodzera, uchifunga zvakasiyana siyana, senge kushushikana uye kunetsa uye masimba, uye kuve nechokwadi chekuvimbika uye kushanda kwakanaka.
Mechanical dhizaini inosanganisira dhizaini yemuchina, dhizaini yezvimiro, dhizaini dhizaini uye dhizaini yechigadzirwa. Dhizaini yechigadzirwa ine chekuita nekugadzirwa kwezvinhu zvemuviri senge zvinhu zvevatengi, zvigadzirwa zvemaindasitiri nezvimwe zvinobatika. Dhizaini yemuchina, kune rumwe rutivi, inotarisana nekugadzira michina yakaita seinjini, maturbine uye michina yekugadzira. Mechanism dhizaini ine chekuita nekugadzira masisitimu anoshandura zvinopinza kuita zvinodiwa zvinobuda. Magadzirirwo ekugadzira ndiyo danho rekupedzisira. Inosanganisira kuongororwa uye dhizaini yezvivakwa zvakaita semabhiriji, zvivakwa, uye mafuremu esimba rawo, kugadzikana, kuchengeteka, uye kusimba.
Iyo chaiyo dhizaini maitiro akaita sei?
Maitiro ekugadzira anowanzo sanganisira matanho akasiyana, sekuzivikanwa kwedambudziko rekutsvagisa uye ongororo, kugadzirwa kwemazano uye dhizaini yakadzama uye prototyping, pamwe nekuyedza uye kujekesa. Muzvikamu izvi mainjiniya anoshandisa hunyanzvi hwakasiyana uye maturusi senge komputa-inobatsira dhizaini (CAD) software, inopera chinhu chekuongorora (FEA) uye simulation kuratidza nekuvandudza dhizaini.
Zvinhu zvipi zvinofanira kufungwa nevagadziri?
Mechanical dhizaini inowanzo batanidza zvinhu zvakaita sekugadzira, ergonomics, mutengo-kushanda pamwe nekuchengetedza. Mainjiniya anoedza kugadzira mamodheru asingangoite uye anoshanda asi, ivo vanofanirwawo kufunga nezvezvinodiwa nemushandisi, kukanganisa kwezvakatipoteredza uye kushomeka kwehupfumi.
Izvo zvakakosha kuti uyeuke kuti iyo ndima yekugadzira mechanic inzvimbo yakakura uye inoramba ichishanduka ine zvinhu zvitsva, matekinoroji uye nzira dziri kugara dzichigadzirwa. Nekudaro, vanogadzira michina vanofanirwa kugara vachivandudza hunyanzvi hwavo neruzivo kuti varambe vari pamberi mukufambira mberi kwetekinoroji.
Anotevera ndiwo mapoinzi eruzivo nezve dhizaini yekugadzira yakaunganidzwa uye yakarongwa neAnebon's engineering timu kuti igovane nevamwe vaunoshanda navo.
1. Izvo zvinokonzeresa kutadza mune zvemakanika zvikamu ndezvi: general kuputsika kana kuwandisa kwasara deformation kukuvara kwepasiprecision yakashandura zvikamu(corrosion wear, friction kuneta uye kupfeka) Kukundikana nekuda kwemigumisiro yemamiriro ekushanda.
2. Zvikamu zvekugadzira zvinofanira kukwanisa kuzadzisa: zvinodiwa zvekudzivisa kukundikana mukati menguva yakatarwa (simba kana kuoma, nguva) uye zvinodiwa zvemaitiro ekugadzirisa, zvido zvehupfumi, pasi pemhando yezvinodiwa, uye zvinodiwa zvekuvimbika.
