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

Yandiswa

I-hinges eguquguqukayo ifumene ingqalelo ebaluleke kakhulu kwizixhobo ezichanekileyo ngenxa yokwazi kwabo ukuhambisa intshukumo okanye amandla ngengcaciso ye-elastic endaweni yamacandelo aphezulu. Xa kuthelekiswa nentshukumo yesiqhelo eshukumayo, i-hinges eguqukayo inika izibonelelo ezinje ngesisombululo esiphezulu sokuhambisa, akukho xinzelelo, akukho hlaselo, kunye nenkqubo elula yokwenza. Zisetyenziswe ngokubanzi kwizixhobo ezahlukeneyo zokungalunganga, kubandakanya ne-Lenses yeNjongo yeLinya, i-microscopes ye-elektroniki, iskekelo ze-elektroniki, i-Spanical SpiresCos, indawo yokujonga i-SPEAT, NOKUGQIBELA Iiparamitha eziphambili zeendlela ezihambelana nazo, njengeendawo eziguqukayo, ifuthe ngokuthe ngqo iimpawu ezinamandla kunye nokubonisa ukuchaneka kwesiphelo. Ke ngoko, uphando olubanzi lwenziwe ukuze luqonde ukuguquguquka kwee-hinge eziguqukayo. Eli phepha lijolise ekufundeni iMatrix yokuguquguquka kwematriki ethe tye atyebileyo ajikelezile, ihlalutya iiparamitha, kwaye ibonelele ngesiseko sethiyori yoyilo lwabo kunye nokwenza oko.

Ukuguquguquka kwematrix ye-beam ethe qengqelekayo:

I-Bleamere ethe tye ejikelezwe i-hinge iqulethe ulwakhiwo oluthe ngqo lwephepha kunye neekona ezijikeleziweyo kwiziphelo ze-hinge ukunqanda uxinzelelo. Iiparamitha eziphambili zejometri zibandakanya ukuphakama kwe-hinge (h), ubude be-hingee (l), ubukhulu be-hinge Ukuhlalutya i-hinge ye-hinge, indlela yolwabiwo lohlalutyo ngokusekwe kwi-cantilever ye-cantilever ye-cantilever ifunyenwe. Le ndlela ichaza imodeli yohlalutyo lwe-loop evaliweyo kwi-Matrix ye-In-Plexix ye-hinge eguqukayo. Ukongeza, ifomula elula yokuBala ye-Matrix ye-terix inikezelwe xa umyinge we-hinge ye-hinge ye-hinge i-radius ukuya kuthi ga.

Ukuqinisekiswa kwenqaku eliqinisekileyo:

Ukuqinisekisa ifomula yehlalutyo ethathiweyo, imodeli yenqaku eligqibeleleyo le-Bleam eqondiswe i-hinge e-hinge isetyenziselwe ukusetyenziswa kwesoftware ye-UGNTRARY. Iziphumo zemodeli yemodeli ye-fitel ithelekiswa neenqobo zokuhlalutya iiparamitha eziguquguqukayo. Impazamo yesihlobo phakathi kwezi zimbini zihlalutywe ngohlobo ezahlukeneyo kwimidlalo ye-hinge e-chinges, ezinjengomlinganiso we-hinge ubude (l / t) kunye nomyinge we-hinge

Iziphumo:

Uhlalutyo lubonisa ukuba kumgangatho we-L / T ngaphezulu okanye ukulingana no-4, impazamo phakathi kwexabiso le-matrix ye-Matrix iphakathi kwe-5.5%. Nangona kunjalo, kwi-L / T I-G / T i-4, imposiso yesihlobo inkulu ngenxa yokungakwazi ukwenza lula i-cantilever ibe ngumgodi wecawa. Oku kubonisa ukuba imodeli yohlalutyo evaliweyo ilungele iimeko ezinkulu ze-L / T.

Ngokuphathelele umlinganiso r / t, uhlalutyo lutyhila ukuba xa i-0,1 ≤ R / T ≤ ≤ ≤ I-0.5, impazamo phakathi kwexabiso lokuhlalutya kunye nezemilinganiselo ilawulwa ngaphakathi kwe-9%. Ukongeza, xa u-0,2 ≤ R / T ≤ 0.3, impazamo yesalamane inokulawulwa ngaphakathi kwe-6.5%. Ezi zinto zifunyenweyo zibonisa ukuchaneka kunye nokusetyenziswa kwemodeli yohlalutyo lwe-loop evaliweyo yokuguqula i-matrix.

Imodeli yohlalutyo lwe-loop evaliweyo ephuhliswe kolu phononongo ibonelela ngesiseko sethiyori yoyilo kunye nenkqubo ye-BIGS BUMED BIGEST. Uhlalutyo lubonakalisile ukuba imodeli inokuqikelela ngokuchanekileyo iparameter ye-matrix xa ujonga umahluko kubude be-hingede, kunye ne-radius ye-hinge. Ezi zinto zifunyanisiweyo ziya kuba negalelo ekuqhubeni phambili kweendlela ezihambelana nezicelo zazo kwizixhobo ezichanekileyo.
