Kupanga ndi Kusanthula kwa Chidziwitso Chatsopano Chowongoka Chozungulira Hinge_Hinge

Zasinthidwa

Ndemanga:

Kuti mukhale ndi hinji yosunthika yokhala ndi kusinthasintha kosinthika komanso kusinthasintha kwapamwamba, kamangidwe kake ka hinji yowongoka yozungulira idapangidwa. Kusinthasintha, kulondola, komanso kutopa kwa hinji yatsopanoyi adafaniziridwa ndikuwunikidwa motsutsana ndi hinji yozungulira yowongoka. Zotsatira zake zidawonetsa kuti hinji yozungulira yowongoka yatsopanoyo idawonetsa kusinthasintha kwakukulu komanso kusinthasintha kwapamwamba poyerekeza ndi hinji yakale. Moyo wotopa wa mahinji onsewa uli pafupi ndi wopandamalire. Ponseponse, hinji yosinthika yatsopanoyo idapambana kwambiri ndi hinji yachikhalidwe ndikukwaniritsa zofunikira zamapangidwe.

Mahinji osinthika akhala akufufuzidwa mozama chifukwa chogwiritsa ntchito makina ang'onoang'ono amagetsi, zida zolondola, komanso kuwongolera ma micromanipulation. Mahinjiwa ndi ang'onoang'ono kukula kwake, opanda polekezera, alibe kugunda kwa makina, komanso omvera kwambiri. Ofufuza awonetsa chidwi ndi mapangidwe a hinges osinthika [1-3]. Zofunikira za hinges zosinthika zimaphatikizapo kuuma (kusinthasintha), kulondola, ndi kupsinjika maganizo [4-5]. Popeza ma hinges osinthika amatha kulephera kutopa poyerekeza ndi zida zolimba, kusanthula kutopa ndikofunikira panthawi yopanga [6-7].

Mu pepala ili, mawonekedwe atsopano a hinge yowongoka yozungulira akuwonetsedwa. Kusinthasintha, kulondola, komanso kutopa kwa hinge iyi kumawunikidwa pogwiritsa ntchito pulogalamu yomaliza ya Workbench 15.0. Kagwiridwe ka hinji katsopano kamafananizidwa ndi hinji yachikhalidwe yowongoka yozungulira.

2. Hinge Performance Analysis

Kuti mupange hinji yodalirika yosinthasintha, m'pofunika kupenda zofunikira zake. Zofunikira zazikulu zogwirira ntchito za hinge yosinthika zimaphatikizapo kusinthasintha, kulondola, komanso moyo wotopa.

2.1 Kusanthula Kusinthasintha

Kusinthasintha (kuuma) ndi gawo lofunikira pamapangidwe a hinges osinthika. Equation (1) ikuwonetsa kuti magawo ena akamakhala osasinthasintha, m'lifupi mwake (b) kumapangitsa kusinthasintha kwakukulu. Chifukwa chake, hinji yozungulira yowongoka yatsopano, yokhala ndi m'lifupi mwake (b1), imawonetsa kusinthasintha kwamphamvu. Kusanthula kwazinthu zomaliza pogwiritsa ntchito Workbench 15.0 kunachitika kuti zitsimikizire kusinthasintha kwa mahinji awiriwo. Zomwezo zakuthupi, katundu, ndi malire zinagwiritsidwa ntchito pazitsulo zonse ziwiri. Chitsulo chosapanga dzimbiri, chokhala ndi zotanuka modulus ya 190 GPa ndi chiŵerengero cha Poisson cha 0.305, chinasankhidwa kukhala chopangira chitsanzo cha hinge. Miyeso ya hinji yozungulira yozungulira yozungulira inali: kutalika kwa hinji (a) = 30 mm, m'lifupi (b) = 10 mm, kutalika (h) = 10 mm, makulidwe ochepa (t) = 1 mm, ndi arc radius (r. = 4.5 mm
