Simulation Ongororo yeHinge Spring Yakavakirwa paMatlab uye Adams_Hinge Ruzivo

Nyaya Yakanyorwa Patsva:

"Abstract: Chinyorwa ichi chine chinangwa chekugadzirisa nyaya dzemafambiro akareba ekusimudzira uye kusakwana kwakakwana mukuongororwa kwekufamba kweazvino kuvhura nekuvhara kwemotokari zvikamu. Nekushandisa Matlab, iyo kinematics equation yehinge yebhokisi regirovhosi mune modhi yemotokari inomiswa, uye iyo yekufamba curve yechitubu mune hinge michina inogadziriswa. Pamusoro pezvo, mechanic system software inonzi Adams inoshandiswa kumisikidza meshini yekufambisa modhi uye kuitisa simulation ongororo pane inoshanduka hunhu hwesimba rekushandisa uye kutamiswa kwebhokisi regirovhosi panguva yekugadzira danho. Mhedzisiro yacho inoratidza kuti nzira mbiri dzekuongorora dzine kuenderana kwakanaka, kuvandudza kugona kwemhinduro uye nekupa hwaro hwe theoretical hweyakakwana hinge meshini dhizaini.

Iko kukurumidza kusimudzira kweindasitiri yemotokari uye tekinoroji yekombuta kwatungamira kune yakakwira zvinodiwa nevatengi pakugadzirisa chigadzirwa. Kupfuura chitarisiko chakakosha uye mabasa, dhizaini yemotokari ikozvino inosanganisira akasiyana maitiro ekutsvagisa. MuEuropean Auto Show, iyo matanhatu-link hinge michina inoshandiswa zvakanyanya mukuvhura mota nekuvhara zvikamu. Iyi hinge michina haingope chitarisiko chakanaka uye chisimbiso chiri nyore, asi zvakare inogonesa kufamba nekushandura kureba kwechimwe nechimwe chinongedzo, hinge point chinzvimbo, uye chitubu coefficient. Izvi zvinobvumira kudzora maitiro emuviri.

Mechanism kinematics inonyanya kudzidza mafambiro ehukama pakati pezvinhu, kunyanya hukama pakati pekutamiswa, kumhanya, uye kukurumidza nenguva. Yechinyakare meshini kinematics uye dynamics ongororo inogona kupa ongororo yeakaoma meshini kufamba, kunyanya kufamba kwekuvhura nekuvhara kwemotokari. Nekudaro, zvinogona kunetsa kukurumidza kuverenga mhedzisiro inoenderana neinjiniya dhizaini zvinodiwa.

Kuti ugadzirise izvi, iyo hinge modhi yebhokisi regirovhosi mune modhi yemotokari inodzidzwa. Nekutevedzera uye kuverenga iro remanyorero kuvhura uye kuvhara chiito chebhokisi regirovhosi, iyo yekufamba curve yehinge chitubu inogadziriswa uchishandisa Matlab. Uyezve, modhi yejometri inotangwa muAdams uchishandisa chaiyo prototype tekinoroji, uye akasiyana kinematic paramita akaiswa kuti aite simulation ongororo uye ongororo. Izvi zvinovandudza kugadzirisa kwekugadzirisa uye kupfupisa kutenderera kwekugadzirwa kwechigadzirwa.

2 Hinge Mechanism yeGlove Bhokisi

Bhokisi regirovhosi mukati mekabhini yemotokari rinowanzo shandisa hinge-mhando yekuvhura michina, inoumbwa nezvitubu zviviri uye akawanda ekubatanidza tsvimbo. Nzvimbo yevhavha pane chero kona yekuvhura yakasiyana. Izvo zvinodikanwa zvekugadzira zvehinge yekubatanidza michina zvinosanganisira kuve nechokwadi kuti nzvimbo yekutanga yebhokisi chivharo uye mapaneru zvinoenderana nezvinodiwa nedhizaini, zvichiita kuti nzvimbo yekuvhura iri nyore yevarimo vatore nekuisa zvinhu pasina kukanganisa zvimwe zvivakwa, uye kuve nechokwadi chekuvhura nekuvhara kuri nyore nekushanda. chivharo chakavimbika kana chivharo chiri pakona kwayo yepamusoro yekuvhura.

Iyo yakanyanya kuvhurwa kwebhokisi regirovhosi inonyanya kutsanangurwa nekurohwa kwechirimo. Nekuverenga kutama uye kumanikidza shanduko yezvitubu zviviri zvehinge panguva yekutambanudza uye yekumanikidza, mutemo wekufamba wehinge mechanism inogona kuwanikwa.

3 Matlab Numerical Calculation

3.1 Hinged Four-bar Linkage Mechanism

Iyo hinge yekubatanidza masisitimu iri nyore muchimiro, iri nyore kugadzira, inogona kutakura mutoro wakakura, uye iri nyore kuona inozivikanwa mitemo yekufamba uye kuburitsa inozivikanwa mafambiro trajectories, ichiita kuti ishandiswe zvakanyanya mukugadzira engineering. Nekushandura chimiro uye saizi yezvikamu, kutora zvikamu zvakasiyana semafuremu, kudzorera kinematic pair, uye nekuwedzera iyo inotenderera peya, hinge mana-bar yekubatanidza nzira inogona kushanduka kuita nzira dzakasiyana dzekubatanidza.

Iyo chinzvimbo equation yeiyo yakavharwa vector polygon ABFO muCartesian coordinate system inotangwa. Nekushandura iyo equation kubva kune vector fomu kuita yakaoma fomu uchishandisa Euler's formula, izvo chaizvo uye zvekufungidzira zvikamu zvinopatsanurwa.

2.1 Motion Ongororo yeHinge Spring L1

Iyo meshini yakaodzwa kuita maviri-mabha anongedzo kugadzirisa mutemo wekufamba wehinge chitubu L1 uchishandisa nzira yekuongorora. Shanduko yehurefu yechirimo L1 inoverengerwa sekuchinja kwekutama kweHI mugonyo nhanhatu FIH.

Kumhanyisa chirongwa cheMatlab kunopa mafambiro eiyo hinge chitubu L1 panguva yekuvhara kwechivharo.

2.2 Motion Ongororo yeHinge Spring L2

Zvakafanana nekuongorora kwehinge chitubu L1, michina yacho yakaodzwa kuita maviri-mabha anongedzo kugadzirisa mutemo wekufamba wehinge spring L2. Shanduko yehurefu yechitubu L2 inoverengerwa seshanduko yekutamiswa kweEG mugonyonhatu EFG.

Kumhanyisa chirongwa cheMatlab kunopa mafambiro ehinge chitubu L2 kana chivharo chiri kuvhara.

Ichi chidzidzo chinomisikidza kinematic equations yehinge spring mechanic uye inoita modhi uye simulation yekuongorora mafambiro emitemo yehinge springs. Iko kugona uye kuenderana kweMatlab analytical nzira uye Adams simulation nzira inosimbiswa.

Iyo Matlab yekuongorora nzira inobata data rakasiyana, nepo Adams modhi uye simulation zviri nyore, kuvandudza kugadzirisa kwemhinduro. Kuenzanisa pakati penzira mbiri idzi kunoratidza kusiyana kuduku mumigumisiro, zvichiratidza kuwirirana kwakanaka.

Mukupedzisa, chidzidzo ichi chinopa ruzivo rwekuvandudza kutenderera kwekusimudzira uye kugadzirisa kushanda kwemotokari kuvhura nekuvhara zvikamu, pamwe nehwaro hwekufungidzira hweyakakwana dhizaini yehinge."
