Abstract:

Ukufezekisa ihenjisi eguquguqukayo kunye nokuguquguquka okuphuculweyo kunye nokuchaneka okuphezulu okujikelezayo, uyilo lwenoveli yehenjisi ejikelezayo ethe tye yaphuhliswa. Ukubhetyebhetye, ukuchaneka, kunye nobomi bokudinwa kwale hinge intsha bathelekiswe kwaye bahlalutywa ngokuchasene nehenjisi ebhetyebhetye yesiqhelo ejikelezayo. Iziphumo zibonise ukuba ihenjisi entsha ethe nkqo ejikelezayo ebhetyebhetye ibonise ukuguquguquka okukhulu kunye nokuchaneka okuphezulu kokujikeleza xa kuthelekiswa nehenjisi yemveli. Ubomi bokudinwa kweehenjisi zombini busondele kwisiphelo. Lilonke, ihenjisi entsha ebhetyebhetye isebenze ukodlula ihenjisi yemveli kwaye yahlangabezana neemfuno zoyilo.

Iihinge eziguquguqukayo ziye zaba ngumxholo wophando olubanzi ngenxa yezicelo zabo kwiinkqubo ze-micro-electromechanical, i-instrumentation echanekileyo, kunye ne-micromanipulation. Ezi hinge zincinci ngobungakanani, azinasikhewu, azinangquzulwano ngoomatshini, kwaye zinobuntununtunu. Abaphandi baye babonisa umdla ekuyilweni kweehinge eziguquguqukayo [1-3]. Iimpawu ezibalulekileyo zeehenjisi eziguquguqukayo ziquka ukuqina (ukuguquguquka), ukuchaneka, kunye neempawu zoxinzelelo [4-5]. Ekubeni iihinge eziguquguqukayo zixhomekeke ekuphelelweni kokukhathala xa kuthelekiswa nezakhiwo eziqinileyo, uhlalutyo lokukhathala luyimfuneko ngexesha lesigaba soyilo [6-7].

Kweli phepha, uyilo olutsha lwehenjisi ethe tye eguquguqukayo ejikelezayo ivezwa. Ukuguquguquka, ukuchaneka, kunye nobomi bokudinwa kwale hinge buhlalutywa kusetyenziswa isoftware yesoftware Workbench 15.0. Ukusebenza kwehenjisi entsha kuthelekiswa naleyo yehenjisi ethe tye esetyhula ebhetyebhetye.

2. Uhlalutyo lweNtsebenzo yeeHinge

Ukuyila ihenjisi ethembekileyo eguquguqukayo, kubalulekile ukuhlalutya iimpawu zayo eziphambili. Iiparamitha eziphambili zokusebenza zehenjisi ebhetyebhetye ziquka ukuguquguquka, ukuchaneka, kunye nobomi bokudinwa.

2.1 Uhlalutyo lokuguquguquka

Ukuguquguquka (ukuqina) luyilo olubalulekileyo iparameter yeehenjisi eziguquguqukayo. I-equation (1) ibonisa ukuba xa ezinye iiparameters zihlala zingatshintshi, ububanzi behinge encinci (b) kubangela ukuguquguquka okukhulu. Ke ngoko, ihenjisi entsha esetyhula ethe tye ebhetyebhetye, enobubanzi obumxinwa bokusika (b1), ibonisa ukuguquguquka okuphuculweyo. Uhlalutyo lwezinto ezigqityiweyo kusetyenziswa i-Workbench 15.0 yenzelwe ukuqinisekisa ukuguquguquka kweehenjisi ezimbini. Iipropati eziphathekayo ezifanayo, umthwalo, kunye neemeko zomda zaye zasetyenziswa kuzo zombini iihenjisi. Insimbi engenasici, ene-elastic modulus ye-190 GPa kunye ne-Poisson's ratio ye-0.305, yakhethwa njengesixhobo semodeli yehinge. Imilinganiselo yehenjisi yehinge ebhetyebhetye ngokwesiko yesiqhelo yayi: ubude behinge (a) = 30 mm, ububanzi (b) = 10 mm, ubude (h) = 10 mm, ubuncinane bobunzima (t) = 1 mm, kunye ne-arc radius (r ) = 4.5 mm
