Idizayini Nokuhlaziywa Kolwazi Olusha Oluqondile Oluyi-Round Hinge_Hinge

Kubuyekeziwe

Abstract:

Ukuze kuzuzwe ihinge eguquguqukayo enokuguquguquka okuthuthukisiwe nokunemba okuphezulu kokujikeleza, idizayini yenoveli yehinji eyindilinga eguquguqukayo eqondile yasungulwa. Ukuvumelana nezimo, ukunemba, kanye nempilo yokukhathala yale hinge entsha kwaqhathaniswa futhi kwahlaziywa ngokumelene nehinji eyindilinga eqondile evamile eguquguqukayo. Imiphumela yabonisa ukuthi ihinge entsha eyindilinga evumelana nezimo ibonise ukuguquguquka okukhulu nokunemba okuphezulu kokuzungeza uma kuqhathaniswa nehinji evamile. Impilo yokukhathala yawo womabili amahinge iseduze nokungapheli. Sekukonke, ihinge entsha eguquguqukayo isebenze kangcono kunehinge evamile futhi yahlangabezana nezidingo zedizayini.

Amahinge aguquguqukayo abe yisihloko socwaningo olunzulu ngenxa yokusetshenziswa kwawo ezinhlelweni ze-micro-electromechanical, ukunemba kwezinsimbi, kanye nokukhohlisa okuncane. Lawa mahinge mancane ngosayizi, awanayo igebe, awanakho ukungqubuzana komshini, futhi azwela kakhulu. Abacwaningi babonise isithakazelo ekwakhiweni kwamahinge aguquguqukayo [1-3]. Izakhiwo ezibucayi zamahinge aguquguqukayo zifaka ukuqina (ukuguquguquka), ukunemba, nezici zokucindezeleka [4-5]. Njengoba amahinge aguquguqukayo athambekele ekuhlulekeni kokukhathala uma kuqhathaniswa nezakhiwo eziqinile, ukuhlaziya ukukhathala kuyadingeka phakathi nesigaba sokuklama [6-7].

Kuleli phepha, kwethulwa umklamo omusha wehinji eyindilinga eguquguqukayo eqondile. Ukuguquguquka, ukunemba, kanye nempilo yokukhathala yale hinge ihlaziywa kusetshenziswa isoftware yesici esilinganiselwe i-Workbench 15.0. Ukusebenza kwehinge entsha kuqhathaniswa nalokho kwehinji eyindilinga eguquguqukayo evamile.

2. I-Hinge Performance Analysis

Ukuze wakhe ihinge ethembekayo eguquguqukayo, kubalulekile ukuhlaziya izici zayo eziyisisekelo. Imingcele yokusebenza eyinhloko yehinge evumelana nezimo ihlanganisa ukuguquguquka, ukunemba, nempilo yokukhathala.

2.1 Ukuhlaziya Ukuvumelana nezimo

Ukuvumelana nezimo (ukuqina) kuyipharamitha yomklamo ebalulekile yamahinji aguquguqukayo. Isibalo (1) sibonisa ukuthi lapho amanye amapharamitha ehlala engashintshile, ububanzi behinji encane (b) buphumela ekuguquguqukeni okukhulu. Ngakho-ke, ihinge entsha eyindilinga evumelana nezimo, enobubanzi obuncane bokusika (b1), ibonisa ukuguquguquka okuthuthukisiwe. Ukuhlaziywa kwesici esiphelile kusetshenziswa i-Workbench 15.0 kwenziwa ukuze kuqinisekiswe ukuguquguquka kwamahinge amabili. Izakhiwo ezibonakalayo ezifanayo, umthwalo, nezimo zomngcele zasetshenziswa kuwo womabili amahinge. Insimbi engagqwali, enemodulus enwebekayo engu-190 GPa kanye nesilinganiso se-Poisson sika-0.305, ikhethwe njengento esetshenziswayo yemodeli yehinge. Ubukhulu behinji eyindilinga eqondile yendabuko eguquguqukayo babuyi: ubude behinge (a) = 30 mm, ububanzi (b) = 10 mm, ubude (h) = 10 mm, ubuncane bokujiya (t) = 1 mm, kanye ne-arc radius (r ) = 4.5 mm
