Kupanga ndi kufufuza kwa hinge yosinthika yooneka ngati Y_Industry News

Ndi kupita patsogolo kwachangu kwa makina amakono kupita ku liwiro lalitali komanso kulondola kwambiri, pakufunika kufunikira kwa mahinji osinthika ndi njira zomwe zimagwirizana m'magawo osiyanasiyana monga maloboti ang'onoang'ono, zida zowoneka bwino, magalimoto apamlengalenga, ndi zida zamafakitale. Mahinjiwa amapereka zabwino monga kusakhala ndi mipata, kukana kukhudzidwa, komanso kuvala [1-5]. Mahinji osinthika amatha kugawidwa ngati mtundu wa micro-motion kapena mtundu wa sitiroko yayikulu kutengera sitiroko yawo. Ngakhale kuti kafukufuku wochuluka wachitidwa pazitsulo zosinthika ndi akatswiri padziko lonse lapansi [6-7], pali zolephera zina zokhudzana ndi kupunduka kwakukulu ndi sitiroko yaikulu. Chifukwa chake, ofufuza akuyang'ana kwambiri kupanga ma hinji osinthika omwe amapereka kulondola kwambiri, kulimba kwapamtunda kwakutali, komanso mawonekedwe osavuta kuti akwaniritse kufunikira kowonjezereka kwa njira zofananira.

Njira zosiyanasiyana zaperekedwa kuti ziwongolere mahinji osinthika okhala ndi mapindika akulu komanso sitiroko yayikulu. Li Zongxuan et al. adayambitsa njira yojambula yopanda mawonekedwe kuti apange hinge yamtundu wa Cartwheel-biaxial flexible hinge [8], pomwe Chen Guimin et al. anakonza hinge yopingasa yozama kwambiri yokhala ndi kulondola kwambiri komanso kutengera njira zowerengera zozungulira, kulondola kozungulira, komanso kupsinjika kwakukulu [9]. Zong Guanghua et al. adapanga hinge yosunthika ya hyperbolic yokhala ndi maubwino monga ngodya yayikulu yozungulira komanso kukhazikika kwakukulu, koma idaperekanso zovuta monga mawonekedwe ovuta komanso kusuntha kwakukulu kwa axis [10]. Kikuchi N ndi Bi Shusheng anakonza hinji yosinthasintha masamba yomwe imakhala yolondola kwambiri komanso yozungulira koma imakhala ndi mawonekedwe ovuta [11-12]. Goldfarb et al. adapanga hinge yosinthika ya migolo yogawanika yomwe imathandizira kozungulira ya 150 °, kukulitsa kuchuluka kwa mahinji osinthika [13]. Smith anakonza cholumikizira chozungulira ngati mbiya chokhala ndi mpanda wokhala ndi mipanda yopyapyala yomwe imawonetsa kugwedezeka pang'ono kwa axial koma ndizovuta kwambiri pamapangidwe ndi kupanga [14].

Ngakhale mahinji osinthika omwe tawatchulawa apita patsogolo kwambiri, akuwonetsabe zinthu monga kusuntha kwa axis, kulimba kwapang'onopang'ono, komanso mawonekedwe ovuta. Kuti athane ndi zofooka izi, pepalali likupereka hinge yosinthika yamtundu wa Y, yomwe imawunikidwa ndikuphunziridwa pogwiritsa ntchito pulogalamu ya ANSYS ndi ADAMS. Hinge yosinthika imapangidwa pogwiritsa ntchito chida chowongolera manambala ndikusonkhanitsidwa. Kuyenda kwa axis kwa hinge yosinthika yooneka ngati Y kumayesedwa kudzera muzoyeserera, ndipo kuyesa kozungulira kozungulira kumachitika papulatifomu yofananira ya 3-RRR.

Mapangidwe a hinge yosinthika yamtundu wa Y imaphatikizapo kapangidwe kachiwembu komanso kutsimikiza kwapakati pa kuzungulira. Hinge yopindika yooneka ngati Y imakhala ndi ndodo ziwiri zolimba ndi akasupe a masamba ooneka ngati arc, pomwe mbali yapakati ya akasupe a masamba ndi 135 °. Solidworks2014 imagwiritsidwa ntchito popanga ma 3D ndikuyerekeza kuti mudziwe pakati pa kasinthasintha. Njira yabwino yokhazikitsira ndi zofunikira paulendo zimatsimikiziridwanso, ndipo kuyerekezera kwa kinematics kumachitika pogwiritsa ntchito Solidworks2014.

Kuti mutsimikizire kulondola kwamayendedwe ndi mawonekedwe akulu ozungulira a hinge yamtundu wa Y, magawo omaliza a mesh ndi kayeseleledwe koyenda amachitidwa pogwiritsa ntchito zida za pulogalamu ya ANSYS ndi ADAMS. Zomwe zimachitikazo zimakonzedwa ndikuwunikidwa pogwiritsa ntchito MATLAB, zomwe zimatsimikizira kuti hinge yosinthika ya Y-mtundu imakwaniritsa zofunikira za nsanja yofananira.

Hinge yosinthika yamtundu wa Y imapangidwa mwakuthupi pokonza ndi kusonkhanitsa kasupe wa masamba ndi ndodo yolimba pogwiritsa ntchito zida zosiyanasiyana. Zoyeserera zingapo zimachitika, kuphatikiza kuyeza kwa axis drift ndi kuyesa kwa trajectory pa benchi yoyeserera yofananira. Zotsatira zikuwonetsa kuti hinge yamtundu wa Y imakulitsa kulondola kwa pulatifomu yofananira.

Pomaliza, phunziroli likupereka hinge yosinthika yooneka ngati Y yomwe imathetsa malire a mahinji omwe alipo. Zotsatira zoyeserera zimatsimikizira kuti hinge yosinthika yamtundu wa Y imapereka kulondola kwambiri, mawonekedwe osavuta, ndi ngodya yayikulu yozungulira, kupangitsa kuti ikhale yolowa m'malo mwa awiriawiri ozungulira pamapulatifomu ofananira ndikuwongolera kwambiri kulondola kwawo. AOSITE Hardware, bizinesi yokhazikika, yomwe imadziwika bwino pamsika wapadziko lonse lapansi ndipo imadziwika ndi mabungwe ambiri apadziko lonse lapansi chifukwa chodzipereka popereka chithandizo chabwino kwambiri kwamakasitomala.

Kodi mwakonzeka kulowa m'dziko la {blog_title}? Konzekerani kukopeka ndi zidziwitso zosangalatsa, malangizo othandiza, ndi nkhani zolimbikitsa zomwe zingakusiyeni kufuna zambiri. Kaya ndinu katswiri wodziwa bwino ntchito kapena mukungoyamba kumene ulendo wanu, blog iyi ndi yotsimikizika kuti ikudziwitsani komanso kukulimbikitsani. Chifukwa chake khalani chete, imwani kapu ya khofi, ndipo tiyeni tiwone zonse zomwe {blog_title} ili nazo!
