Ukuhlaziywa Kokulingisa kwe-Hinge Spring Okusekelwe kuMatlab kanye no-Adams_Hinge Knowledge

Isihloko Sibhalwe Kabusha:

"Abstract: Lesi sihloko sihlose ukubhekana nezinkinga zomjikelezo omude wokuthuthukiswa kanye nokunemba okwanele ekuhlaziyweni kokunyakaza kwezingxenye zamanje zokuvula nokuvala izimoto. Ngokusebenzisa iMatlab, i-kinematics equation yehinge yebhokisi legilavu ​​kumodeli yemoto iyasungulwa, futhi ijika elinyakazayo lentwasahlobo kumshini wehinge liyaxazululeka. Ukwengeza, isofthiwe yomshini ebizwa ngokuthi i-Adams isetshenziselwa ukusungula imodeli yokunyakaza kwemishini nokwenza ukuhlaziya okulingisa kuzici eziguquguqukayo zamandla okusebenza kanye nokugudluzwa kwebhokisi lamagilavu ​​phakathi nesigaba sokuklama. Imiphumela ibonisa ukuthi lezi zindlela ezimbili zokuhlaziya zinokungaguquguquki okuhle, zithuthukisa ukusebenza kahle kwesixazululo futhi zinikeze isisekelo sethiyori sokuklanywa kwemishini yamahinge.

Ukuthuthuka okusheshayo kwemboni yezimoto kanye nobuchwepheshe bekhompyutha kuholele ezidingweni eziphakeme zamakhasimende zokwenza ngokwezifiso umkhiqizo. Ngale kokubukeka okuyisisekelo nemisebenzi, idizayini yemoto manje isihlanganisa amathrendi ahlukahlukene ocwaningo. Ku-European Auto Show, umshini wehinge wezixhumanisi eziyisithupha usetshenziswa kakhulu ekuvuleni nasekuvaleni kwezingxenye zemoto. Lo mshini wehinge awuhlinzeki nje ngokubukeka okuhle nokubeka uphawu kalula, kodwa futhi uvumela ukunyakaza ngokushintsha ubude besixhumanisi ngasinye, indawo yehinge point, kanye ne-spring coefficient. Lokhu kuvumela ukulawula izici zomzimba.

I-Mechanism kinematics ifunda ngokuyinhloko ukunyakaza okuhlobene phakathi kwezinto, ikakhulukazi ubudlelwano phakathi kokusuka endaweni, isivinini, kanye nokusheshisa ngokuhamba kwesikhathi. I-kinematics yemishini evamile kanye nokuhlaziywa kwe-dynamics kungahlinzeka ngokuhlaziywa kokunyakaza kwemishini okuyinkimbinkimbi, ikakhulukazi ukunyakaza kokuvula nokuvala imoto. Nokho, kungase kube nzima ukubala ngokushesha imiphumela enembile ehlangabezana nezidingo zedizayini yobunjiniyela.

Ukubhekana nalokhu, imodeli yehinge yebhokisi lamagilavu ​​kumodeli yemoto iyafundwa. Ngokulingisa nokubala isenzo sokuvula nokuvala sebhokisi lamagilavu, ijika elinyakazayo lehinge spring lixazululwa kusetshenziswa iMatlab. Ngaphezu kwalokho, imodeli yejiyomethri iyasungulwa e-Adams kusetshenziswa ubuchwepheshe be-virtual prototype, futhi imingcele ehlukahlukene ye-kinematic isethelwe ukwenza ukuhlaziya okulingisa nokuqinisekisa. Lokhu kuthuthukisa ukusebenza kahle kwesixazululo futhi kunciphise umjikelezo wokuthuthukiswa komkhiqizo.

2 I-Hinge Mechanism ye-Glove Box

Ibhokisi lamagilavu ​​ngaphakathi kwekhabhinethi yemoto ngokuvamile lisebenzisa indlela yokuvula yohlobo lwehinge, elakhiwe iziphethu ezimbili nezinduku zokuxhuma eziningi. Ukuma kwekhava kunoma iyiphi i-engeli yokuvula kuhlukile. Izidingo zedizayini zendlela yokuxhumanisa ihinge zihlanganisa ukuqinisekisa indawo yokuqala yekhava yebhokisi kanye nephaneli kufanelana nezidingo zedizayini, ukunika amandla i-engeli yokuvula elula ukuze abahlali bathathe futhi babeke izinto ngaphandle kokuphazamisa ezinye izakhiwo, kanye nokuqinisekisa ukuthi kulula ukuvula nokuvala ukhiye othembekile lapho ikhava isezingeni eliphezulu lokuvula.

Ukuvulwa okuphezulu kwebhokisi leglavu kunqunywa ngokuyinhloko ukushaywa kwentwasahlobo. Ngokubala ukugudluzwa kanye nokuphoqelela izinguquko zamahinge amabili phakathi nenqubo yokwelula nokucindezelwa, umthetho wokunyakaza we-hinge mechanism ungatholwa.

3 Ukubalwa Kwezinombolo kweMatlab

3.1 Indlela Yokuxhumanisa Amabha Ane-Hinged

Indlela yokuxhumanisa ihinge ilula ngesakhiwo, kulula ukuyikhiqiza, ingathwala umthwalo omkhulu, futhi kulula ukubona imithetho yokunyakaza eyaziwayo futhi ikhiqize kabusha ama-trajectories aziwayo, iwenze isetshenziswe kabanzi ekwakhiweni kobunjiniyela. Ngokushintsha umumo nosayizi wezingxenye, ukuthatha izingxenye ezihlukene njengamafreyimu, ukubuyisela emuva i-kinematic pair, nokukhulisa ipheya ezungezisayo, indlela yokuxhumanisa yamabha amane ehinge ingaguqukela kuzinqubo ezihlukahlukene zokuxhuma.

Isibalo sendawo ye-vector polygon polygon ABFO ohlelweni lwe-Cartesian coordinate siyasungulwa. Ngokuguqula i-equation isuke efomini ivekhtha iye kwifomu eyinkimbinkimbi kusetshenziswa ifomula ka-Euler, izingxenye zangempela nezicatshangelwayo ziyahlukaniswa.

2.1 Ukuhlaziywa kokunyakaza kwe-Hinge Spring L1

Indlela ihlukaniswa yaba izixhumanisi zamabha amane ukuze kuxazululwe umthetho wokunyakaza wehinge spring L1 kusetshenziswa indlela yokuhlaziya. Ushintsho lobude bentwasahlobo L1 lubalwa njengoshintsho lokugudluka lwe-HI kunxantathu FIH.

Ukuqalisa uhlelo lweMatlab kunikeza ijika lokunyakaza lehinge spring L1 phakathi nenqubo yokuvala yesivalo.

2.2 Ukuhlaziywa kokunyakaza kwe-Hinge Spring L2

Ngokufanayo nokuhlaziywa kwe-hinge spring L1, indlela ihlukaniswa yaba izixhumanisi ezimbili zamabha amane ukuze kuxazululwe umthetho wokunyakaza we-hinge spring L2. Ushintsho lobude bentwasahlobo L2 lubalwa njengoshintsho lokugudluka lwe-EG kunxantathu EFG.

Ukuqalisa uhlelo lweMatlab kunikeza ijika elinyakazayo lehinge spring L2 lapho isivalo sivala.

Lolu cwaningo lusungula i-kinematic equations yehinge spring mechanism futhi lenza ukumodela nokulingisa ukuze kuhlaziywe imithetho yokunyakaza yamahinge springs. Ukuba nokwenzeka nokuvumelana kwendlela ye-Matlab yokuhlaziya kanye nendlela yokulingisa i-Adams kuyaqinisekiswa.

Indlela yokuhlaziya yeMatlab iphatha idatha ehlukahlukene, kuyilapho ukumodela kwe-Adams nokulingisa kulula kakhulu, kuthuthukisa ukusebenza kahle kwesixazululo. Ukuqhathanisa phakathi kwalezi zindlela ezimbili kubonisa umehluko omncane emiphumeleni, okubonisa ukungaguquguquki okuhle.

Sengiphetha, lolu cwaningo luhlinzeka ngemininingwane ekuthuthukiseni umjikelezo wokuthuthukiswa nokusebenza kahle kwesixazululo sokuvula nokuvala izingxenye zemoto, kanye nesisekelo sethiyori sokuklanywa kwemishini yamahinge."
