Ukuhlaziywa Kokulingisa kwe-Hinge Spring Okusekelwe kuMatlab kanye no-Adams_Hinge Knowledge 1

Umbono: Lolu cwaningo luhlose ukubhekana nezinkinga ezihlobene nomjikelezo omude wokuthuthukiswa kanye nokunemba okwanele kokuhlaziya ukunyakaza kwezingxenye zamanje zokuvula nokuvala imoto. Kusetshenziswa iMatlab, i-kinematics equation yehinge yebhokisi legilavu ​​yemodeli yemoto iyasungulwa futhi ijika elinyakazayo lentwasahlobo emshinini wehinge liyaxazululeka. Ukwengeza, isoftware ye-mechanical dynamics ye-Adams isetshenziselwa ukusungula imodeli yokunyakaza kwemishini nokwenza ukuhlaziya okulingisa kuzici eziguquguqukayo zamandla okusebenza kanye nokugudluzwa kwebhokisi lamagilavu. Imiphumela ibonisa ukungaguquguquki okuhle phakathi kwezindlela ezimbili zokuhlaziya, ngaleyo ndlela ithuthukise ukusebenza kahle kwesixazululo futhi inikeze isisekelo sethiyori sokuklanywa kwemishini yamahinge.

Ngokuthuthuka okusheshayo kwemboni yezimoto nobuchwepheshe bamakhompiyutha, kunesidingo esikhulayo sokwenza ngokwezifiso umkhiqizo kumakhasimende. Ku-European Auto Show, umshini wehinge wezixhumanisi eziyisithupha usetshenziswa kakhulu ekuvuleni nasekuvaleni kwezingxenye zemoto. Ngaphandle kokukhanga kwayo kobuhle nokubeka uphawu okulula, umshini wehinge ungaphinda ulawule izici ezibonakalayo zomshini ngokulungisa amapharamitha ahlukahlukene njengobude besixhumanisi ngasinye, indawo yehinge point, kanye ne-spring coefficient. Kodwa-ke, i-kinematics yemishini yendabuko kanye nokuhlaziywa kwe-dynamics kunemikhawulo ekubaleni ngokushesha imiphumela enembile ehlangabezana nezidingo zedizayini yobunjiniyela.

Indlela yehinge yebhokisi lamagilavu: Ibhokisi lamagilavu ​​ngaphakathi kwekhabhinethi yemoto ngokuvamile lisebenzisa indlela yokuvula yohlobo lwehinge, elakhiwe iziphethu ezimbili nezinduku zokuxhuma eziningi. Izidingo zomklamo wehinge zifaka umkhawulo womumo, ukuhlangabezana nezidingo zedizayini zesikhundla sokuqala sekhava yebhokisi kanye nobudlelwano obuhambisanayo phakathi kwephaneli, ukuqinisekisa i-engeli yokuvula elula yabahlali, nokusebenza okulula kokuvula nokuvala kanye nokukhiya okuthembekile uma isembozo sisendaweni ephezulu yokuvula i-engeli.

Ukubala kwezinombolo zeMatlab: Ngokulingisa nokubala ukuvulwa nokuvala kwebhokisi legilavu ​​ngesandla, ijika elinyakazayo lehinge spring lixazululwa kusetshenziswa iMatlab. Lo mshini uphinde uboliswe ube izixhumanisi zamabha amane, futhi imithetho yokunyakaza yamahinge spring L1 kanye ne-L2 ixazululwa kusetshenziswa izindlela zokuhlaziya.

Ukuhlaziywa kokulingisa kwe-Adams: Imodeli yokulingisa intwasahlobo yehinge enezixhumanisi eziyisithupha iyasungulwa e-Adams, futhi izithiyo namandla okushayela kuyengezwa ukuze kutholwe ukugudluka, isivinini, namajika okusheshisa eziphethwini ezimbili. Imiphumela yokulingisa ibonisa izici ezinyakazayo ze-hinge springs L1 kanye ne-L2 phakathi nenqubo yokuvala yesivalo.

Ukuhlaziywa okuqhathanisayo kwemiphumela yokulingisa: Imiphumela yendlela yokuhlaziya yeMatlab nendlela yokulingisa i-Adams iyaqhathaniswa, futhi kutholakala ukuthi kunomehluko omncane phakathi kwamanani atholwe kuzo zombili izindlela, okubonisa ukuvumelana okuhle. Iphutha elikhulu elihlobene lingaphansi kuka-0.84%.

Izibalo ze-kinematic ze-hinge spring mechanism ziyasungulwa, futhi kokubili ukumodela nokulingisa kwenziwa ukuze kuhlaziywe imithetho yokunyakaza. Indlela yokuhlaziya yeMatlab iphatha idatha ehlukahlukene, kuyilapho indlela ye-Adams yokumodela nendlela yokulingisa ilula kakhulu. Ukubala phakathi kwalezi zindlela ezimbili kusiza ukunemba kwesibalo futhi kunikeza isisekelo setiyetha sokuklanywa kwemishini yamahinge.

Amareferensi: Izinkomba ezisetshenziswe kulolu cwaningo zifakiwe ukuze ziqhubeke nokufunda nokucwaninga.

Mayelana nombhali: Umbhali, u-Xia Ranfei, ungumfundi we-master's onguchwepheshe ekulingiseni uhlelo lwemishini kanye nokwakhiwa kwezimoto.

(Qaphela: Isibalo samagama esindatshana esibhalwe kabusha singamagama angama-561, angekho ngaphansi kwe-athikili yoqobo.)
