NIDAAMKA SOO SAARKA SOO SAARKA
Socodka wax soo saarka ee birta heerka H ee dibadda guud ahaan waa sida soo socota:
Diyaarinta alaabta ceeriin: Walxaha ceeriin ee lagu sameeyo birta H waa birta sida caadiga ah. Birta birta ah waa in la nadiifiyaa oo la kululeeyaa si ay u shaqeyso oo u qaabeyso.
Daawaynta ka hor: birta birta ah, ka dib marka la kululeeyo, waxaa la geeyaa mishiinka kulul ee duuban si loogu duubo kulul. Warshada duuban, duubabka shaqadu waxay xidhiidh la leeyihiin FFB meelo badan oo dhererka duubka la socda, biilkana waxa loo qaabeeyey si tartiib tartiib ah muuqaal H-qaabeeya.
Qabow shaqaynaysa (ikhtiyaar): Birta H-qaabaysan ka dib rogid kulul h ayaa la farsameeyay qabow, sida sawir rogid qabow, iwm. si loo hagaajiyo saxnaanta iyo tayada dusha birta H-qaabaysan.
Goynta iyo dhamaystirka: H-qaabeeya birta duubista qabow shaqaynaysa shaqo qabow oo shaqaynaysa nooca H-nooca habka wax soo saarka birta ka dib rogid iyo qabow shaqeeya H-qaabeeya birta waxay u baahan tahay in la gooyo oo la dhammeeyo iyada oo loo eegayo baahida macaamiisha si loo buuxiyo cabbirka iyo dhererka shuruudaha gaarka ah.
Daawaynta dusha sare: H birta oogada sare waa nadiif iyo caddayn miridhku. Kormeerka iyo baakaynta: Ku samee kormeer tayo leh birta H ee la soo saaray sida tayada muuqaalka, saxnaanta cabbirka, qalabka farsamada iwm. Marka la tijaabiyo oo la oggolaado, waa la soo guraa oo loo geeyaa macmiilka.

Degenaansho wanaagsan: Qaybta isdhaafka ah ee H-beam waxay siinaysaa xasillooni wanaagsan oo hoos timaada cadaadiska axial iyo xiisadda, taas oo u roon xasilloonida iyo badbaadada qaabdhismeedka.
Dhisme ku habboon: Birta H-qaybta ah ayaa lagu xidhi karaa waji ka waji waxaana lagu rakibi karaa si ku habboon inta dhismuhu socdo, taas oo u wanaagsan horumarka dhismaha iyo hufnaanta dhismaha mashruuca.
Ka faa'iidaysiga kheyraadka sare: Naqshadaynta birta-qaabaysan waxay si buuxda uga faa'iidaysan kartaa waxqabadka birta, baabi'inta qashinka walxaha, waxayna gacan ka geysaneysaa badbaadinta kheyraadka iyo ilaalinta deegaanka.
Codsiga ballaaran: Birta H waxay ku habboon tahay dhammaan noocyada dhismaha, buundada iyo wax soo saarka mishiinka iyo wixii la mid ah, oo leh rajo horumarsan oo wanaagsan.
Baaxadda codsiga: Guud ahaan, birta qaybta H ee caadiga ah waxay leedahay xoog sare, xasillooni wanaagsan, dhismo fudud. Waa nooc ka mid ah alaabada birta qaab dhismeedka muhiimka ah waxaana si weyn loogu isticmaalaa dhammaan noocyada injineerada.
KORMEERKA Alaabada
Shuruudaha kormeerka birta-qaabeeya ee H inta badan waxaa ka mid ah dhinacyada soo socda:
Tayada muuqaalka: Tayada muuqaalka birta-qaabaysan ee H waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada. Dusha sare waa inay noqotaa mid siman oo siman, oo aan lahayn jeexjeexyo muuqda, xoqan, miridhku iyo cillado kale.
Cabirka joomatari: Dhererka, balladhka, dhererka, dhumucda webka, dhumucda flange iyo cabbirada kale ee birta-qaabaysan waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada.
Curvature: Qallooca birta qaabaysan ee H waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada. Waxa lagu ogaan karaa marka la cabbiro in diyaaradaha labada daraf ee birta u qaabaysan H ay barbar socdaan ama la isticmaalayo mitir foorarsi ah.
Maroojin: Qallooca birta-qaabaysan ee H waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada. Waxa lagu ogaan karaa marka la cabbiro in dhinaca birta-qaabka H-ku ay taagan tahay ama ay mitirka maroojinayso.
Weelashada miisaanka: Miisaanka birta-qaabaysan ee H waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada. Miisaanka leexashada waxaa lagu ogaan karaa miisaan.
Halabuurka Kiimikada: Haddii birta H-qaabaysan ay u baahan tahay in la alxanayo ama si kale loo farsameeyo, ka kooban yahay kiimiko waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada.
Guryaha makaanikada: Qalabka farsamada ee birta-qaabeeya waa in ay u hoggaansamaan heerarka la xiriira iyo shuruudaha dalbashada, oo ay ku jiraan xoogga cufan, dhibicda dhalidda, dhererka iyo tilmaamayaasha kale.
Tijaabada aan burburin: Haddii birta qaabka H u baahan tahay tijaabo aan burburin, waa in la tijaabiyaa si waafaqsan heerarka la xiriira iyo shuruudaha dalbashada si loo hubiyo in tayada gudaha ay wanaagsan tahay.
Baakaynta iyo calaamadaynta: Baakaynta iyo calaamadaynta birta qaabaysan ee H waa inay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada si loo fududeeyo gaadiidka iyo kaydinta.
Marka la soo koobo, shuruudaha kor ku xusan waa in si buuxda loo tixgeliyo marka la eegayo H-qaabeeya birta si loo hubiyo in tayadiisa ay la kulanto heerarka ku habboon iyo shuruudaha dalbashada, iyo in la siiyo dadka isticmaala alaabta ugu fiican ee H-qaabeeya.
CODSIGA SOO SAARKA
