Uphando malunga nesiseko se-theoretical yoyilo lweendlela eziguqukayo ze-hinges kunye neendlela eziguqukayo zomzimba1

I-Abstrat: Olu phando lugxile ekufundeni iMatrix ye-Matrix ye-Beam ethe tye ajikeleziweyo. Indlela yokubala yohlaziyo ye-intanethi ye-hinge ithathwe ngokusekwe kwi-cantilever ye-cant. Imodeli yohlalutyo lwe-loop evaliweyo Ukongeza, imodeli ye-hinge ye-hinge iphuhliswa ukuze kuqinisekiswe ukuchaneka kwemodeli yohlalutyo. Impazamo yesihlobo phakathi kwexabiso lohlalutyo kunye nokulinganisa kweeparamitha eziguquguqukayo zeMatrix ihlalutywe iiparamitha ezahlukeneyo ze-hinge. Iziphumo zibonisa ukuba imodeli yohlalutyo ichanekile, kwaye iimpazamo zomzalwane zinokulawulwa ngaphakathi kwemida eyamkelekileyo.

I-hinges eguquguqukayo isetyenziswa ngokubanzi kwizixhobo ezichanekileyo ngenxa yezibonelelo zazo zesigqibo esiphezulu, akukho xinzelelo, kunye nemveliso elula yokwenziwa. Ezi hinges zixhomekeke kwi-desformation yabo yokuphelisa okanye ukuguqula intshukumo, ukunyanzela, okanye amandla, ukuphelisa isidingo sezinto ezingqongqo. Iiparameter eziphambili ze-hinge eguqukayo zichaphazela ngokuthe ngqo iimpawu zayo kunye nokuphela kokuma. Uphando lwangaphambili lugxile kwiindidi ezahlukeneyo ze-hindus eziguquguqukayo, kodwa ziqhutywa izifundo ezithe xhaxhe kwi-BIGES ezithe nkqo. Eli phepha lijolise ekugcwaliseni le nqanaba lophando ngokufunda i-matrix yokuguquguquka kwee-chinges ezinjalo.

1. Ukuguquguquka kweMatrix ye-Matrix ye-Beam ethe nkqo:

Indawo ethe tye ebhengezikileyo eguqukayo i-hinge i-hinge eguqukayo yindawo yephepha elinendawo ejikelezileyo ukuthintela uxinzelelo loxinzelelo. Iiparamitha zejometri ze-hingetric zibandakanya ukuphakama, ubude, ubukhulu, kunye ne-filllet radius. Imodeli yohlalutyo lwe-loop evaliweyo ye-Matrix ye-hinge isekwe ngokusekelwe kwindlela yokubala yohlalutyo lweplanethi ye-intanethi. Iiparamitha eziguquguqukayo zeMatrix ziyahlalutya iiparamitha ezahlukeneyo ze-Hinge

2. Ukuqinisekiswa okuqinisekileyo kwe-matrix yokuguqula:

Ukuqinisekisa ukuchaneka kwemodeli yohlalutyo, imodeli ye-fite ye-hinge yenziwe isebenzisa isoftware ye-UGNX yesoftware. Iziphumo zokwenza i-hinge ezilayishwe ngamandla eyunithi / ngomzuzu uthelekiswa nexabiso lokuhlalutya. Impazamo yesihlobo phakathi kwexabiso lohlalutyo kunye nendlela yokulinganisa yeeparamitha eziguquguqukayo ihlalutywe imilinganiselo eyahlukeneyo yobude be-hinge yobude (i-L / T) kunye ne-Radius kwi-radick (R / T).

2.1 isiphumo se-L / t kwiparamitha yokuguqula i-matrix:

Impazamo yesihlobo phakathi kwexabiso lohlalutyo kunye nokulinganisa kweeparamitha eziguquguqukayo kufuneka zibe ngaphakathi kwe-5.5% xa umlinganiso l / t mkhulu okanye ulingana no-4. Imilinganiselo engaphantsi kwe-4, impazamo yesalamane inyusa kakhulu ngenxa yokusikelwa kwemida ye-Beam ye-Beam. Ke ngoko, imodeli yohlalutyo evaliweyo ilungele i-chinges enemilinganiselo enkulu ye-L / T.

2.2 Isiphumo se-R / t kwiparamitha yokuguqula i-matrix:

Impazamo yesihlobo phakathi kwexabiso lohlalutyo kunye nokulinganisa kweeparamitha eziguquguqukayo zeMatrix enyuka ngokunyuka kwe-R / T. Imilinganiselo ephakathi kwe-0.1 ne-0.5, impazamo yesihlobo inokulawulwa ngaphakathi kwe-9%. Imilinganiselo ephakathi kwe-0.2 ne-0.3, impazamo yesihlobo inokulawulwa ngaphakathi kwe-6.5%.

2.3 Isiphumo se-R / t ngeparamitha eguquguqukayo ye-Matrix:

Iifomula ezilula zenziwe lula kwiiparamitha eziguquguqukayo zeMatrix zibonelelwa ngokujonga umlinganiso r / t. Impazamo yesihlobo phakathi kwexabiso eliphantsi lemigangatho elilula kunye neenqobo zokuxabisa zinyuswa ngokunyuka kwe-R / T. Imilinganiselo ephakathi kwe-0.3 kunye ne-0.2, impazamo yesihlobo inokulawulwa ngaphakathi kwe-9% ne-7%, ngokulandelelana.

Imodeli yohlalutyo oluvaliweyo lwe-loop ye-therix ye-therix ye-Beam ethe tye ijikeleze i-hinges eguqulweyo ibonelela ngesiseko soyilo soyilo kunye nokuphuculwa kweendlela eziguqukayo kunye neendlela. Ukuchaneka kwemodeli kuqinisekisiwe nge-pitel yokufunda, kwaye iimpazamo zomzalwane ziphakathi kwemida eyamkelekileyo yeeparamitha ezahlukeneyo zeHinge. Olu phando lunegalelo ekuqondeni nasekusetyenzisweni kwe-Beam ethe qengqelekayo ejikeleziweyo kwizixhobo ezahlukeneyo zokuchaneka ngokuchanekileyo.
