Izihlalo zabakhubazekile zikagesi, njengethuluzi elivelayo lokuhamba kancane, kancane kancane ziye zaqashelwa abantu abaningi asebekhulile nabakhubazekile. Sithenga kanjani aisihlalo esinamasondo sikagesi esingabizi kakhulu?

Njengomuntu ongaphakathi embonini iminyaka engaphezu kweyishumi, ngithanda ukukusiza kafushane ukuthi ulungise le nkinga ngezici ezimbalwa. Into yokuqala okudingeka siyazi ukuthi iqembu ngalinye nesimo somsebenzisi nesimo sokusebenzisa sihlukile, okuholela ekwehlukaniseni kwemikhiqizo ethengiwe.

Izinto ezijwayelekile zihlukaniswa ikakhulukazi zibe yi-carbon steel, i-aluminium alloy, i-aerospace titanium aluminium alloy ne-magnesium alloy, i-carbon fiber.

1. Insimbi ye-Carbon.

I-Carbon steel frame isetshenziswa kakhulu ezitulweni ezinamasondo ezisindayo kanti ezinye izinhlobo ezikhiqizwa amafektri amancane, izihlalo ezinamasondo ezisindayo zisebenzisa uhlaka lwensimbi ukuze kuthuthukiswe ubulukhuni bomzimba nokuzinza kokushayela, ngokwesibonelo, amaloli amaningi amakhulu anamafreyimu ensimbi kanye nezimoto ezincane ezingasebenzisa i-aluminium kuyisizathu esifanayo, izimboni ezincane zikhiqiza izihlalo zabakhubazekile zisebenzisa amafreyimu ensimbi ngoba lolu hlobo lwezindleko luncane futhi isizathu sokucubungula sincane. Izimboni zisebenzisa amafreyimu ensimbi yingoba adinga umsebenzi omncane nokushisela futhi ashibhile.

2. I-Aluminium ne-titanium-aluminium alloy

I-aluminium ingxubevange kanye ne-titanium aluminium alloy, lezi zinto ezimbili zithatha iningi lemakethe yezihlalo zabakhubazekile zikagesi, ziyi-7001 ne-7003 izinhlobo ezimbili ezahlukene ze-aluminium, okungukuthi, i-aluminium nezinye izinto ezixubile ezingeziwe ezingezwe kuyo, izici zazo ezivamile ukuminyana okuphansi namandla aphezulu, ukumelana okuhle kwe-plasticity nokumelana nokugqwala okuqinile, ukubekezelela ukugqwala okuqinile nokufaka ukugqwala okuqinile, ukumelana nokugqwala okuqinile, ukugqwala nokuqina kwe-titanium. Ingxubevange ye-aluminium yaziwa nangokuthi i-titanium-aluminium alloy ngenxa yamandla ayo nokumelana nokugqwala. Njengoba indawo yokuncibilika ye-titanium iphakeme kakhulu, ifinyelela ku-1942 degrees, ephakeme ngaphezu kwama-degree angu-900 kunegolide, inqubo yokucubungula nokushisela inzima kakhulu ngokwemvelo futhi ayikwazi ukukhiqizwa isitshalo esincane sokucubungula, ngakho-ke izihlalo zabakhubazekile ezenziwe nge-titanium-aluminium alloy zibiza kakhulu. Eyangaphambili ifanele ukusetshenziswa njalo kanye nezimo ezinhle zomgwaqo kanye nezimo zokushayela, kuyilapho abasebenzisi abayisebenzisa njalo, ngokuvamile, badinga ukuyithwala, futhi ngokuvamile ukushayela emigodini nasemigwaqweni enamagquma bangakhetha isihlalo esinamasondo esenziwe nge-titanium-aluminium alloy.

3. Magnesium ingxubevange

I-Magnesium alloy isekelwe ku-magnesium ukujoyina ezinye izakhi ze-alloy. Izici zayo yilezi: ukuminyana okuncane, amandla aphezulu, i-modulus ephezulu yokunwebeka, ukukhishwa okuhle kokushisa, ukumuncwa okuhle kokushaqeka, amandla okumelana nemithwalo yethonya kune-aluminium alloy, esetshenziswa kakhulu i-magnesium-aluminium alloy. I-Magnesium iyinsimbi elula kunazo zonke ezisebenzayo, enamandla adonsela phansi acishe abe izingxenye ezimbili kwezintathu ze-aluminium kanye nekota eyodwa kweyensimbi, kanye nokusetshenziswa kwe-magnesium amafreyimu ezihlalo zabakhubazekileihloselwe ukuzuza "ukukhanya" okwengeziwe ngesisekelo se-aluminium.
