Isibani sezimpawu zomgwaqo siyingxenye ebalulekile yobunjiniyela bezimoto, enikeza ukwesekwa kwemishini enamandla yokuhamba ngokuphephile kwezimoto zomgwaqo. Kodwa-ke, umsebenzi wezibonakaliso zomgwaqo udinga ukudlalwa njalo ngesikhathi senqubo yokufaka, futhi amandla omshini, ukuqina kanye nokuqina lapho kwamukelwa umthwalo kuzocatshangelwa ngokugcwele ekuhleleni kwesakhiwo. Okulandelayo, ngizokwethula indlela yokufaka kahle izigxobo zezibani zezibonakaliso zomgwaqo kanye nezindlela zokuhlobisa izibani zezibonakaliso ezisetshenziswa kakhulu ukuze uqonde.
Indlela yokufaka kahle isibani sesibani sethrafikhi
Kunezindlela ezimbili ezivamile zokubala izigxobo zezibani zesignali: eyodwa ukwenza lula isakhiwo sesibani sesignali sibe uhlelo lwezigxobo ngokusebenzisa izimiso zemishini yokwakha kanye nemishini yezinto ezibonakalayo, bese ukhetha indlela yokuhlela isimo somkhawulo yokuhlola ukubala.
Okunye ukusebenzisa indlela yokubala elinganiselwe yendlela ye-finite element ukuhlola. Nakuba indlela ye-finite element inembe kakhulu ngokusebenzisa umshini wokubala, yayisetshenziswa kabanzi ngaleso sikhathi ngoba indlela ye-limit state inganikeza iziphetho ezinembile futhi indlela yokubala ilula futhi kulula ukuyiqonda.
Isakhiwo esingaphezulu sesigxobo sesiginali ngokuvamile siyisakhiwo sensimbi, futhi indlela yokuhlela isimo somkhawulo esekelwe kumbono wamathuba iyakhethwa. Ukuhlela kusekelwe esimweni somkhawulo somthamo wokuthwala kanye nokusetshenziswa okuvamile. Isisekelo esingezansi siyisisekelo sekhonkrithi, kanti ukuhlela kwethiyori kobunjiniyela besisekelo kuyakhethwa.
Amadivayisi avamile esignali yethrafikhi kubunjiniyela bethrafikhi alandelayo
1. Uhlobo lwekholomu
Izinti zezibani zesignali zohlobo lwezinsika zivame ukusetshenziselwa ukufaka izibani zesignali ezisizayo kanye nezibani zesignali zabahamba ngezinyawo. Izibani zesignali ezisizayo zivame ukufakwa ezinhlangothini zesobunxele nakwesokudla zomzila wokupaka.
2. Uhlobo lwe-Cantilever
Isibani sesiginali esine-cantilevered sakhiwe ngesigxobo esiqondile kanye nengalo evundlile. Inzuzo yale divayisi ukusebenzisa idivayisi kanye nokulawula imishini yesiginali ezindaweni zokuhlangana zezigaba eziningi, okunciphisa ubunzima bokubeka ugesi wobunjiniyela. Ikakhulukazi, kulula ukuhlela izinhlelo eziningi zokulawula isiginali ezindaweni zokuhlangana zethrafikhi eziyinkimbinkimbi.
3. Uhlobo lwe-cantilever oluphindwe kabili
Isibani sesibani se-cantilever esiphindwe kabili sakhiwe yi-pole eqondile kanye nezingalo ezimbili eziphambeneyo. Sivame ukusetshenziselwa imizila emikhulu kanye neyokusiza, imigwaqo emikhulu kanye neyokusizayo noma imigwaqo enobunjwa obungu-T. Izingalo ezimbili eziphambeneyo zingalingana ngokuvundlile futhi zingasetshenziswa ngezinhloso eziningi.
4. Uhlobo lwe-Gantry
Isibani sesibani sohlobo lwe-gantry sivame ukusetshenziswa esimweni lapho umgwaqo omkhulu ubanzi khona futhi kudingeka kufakwe izinsiza eziningi zesignali ngesikhathi esisodwa. Sivame ukusetshenziswa emnyango womhubhe kanye nomnyango wasemadolobheni.
