Selelekela: Mechini ea ho etsa liteko tsa tensile e sebelisoa ho lekanya matla le elasticity ea thepa.Hangata li sebelisoa liindastering tse kang ho etsa thepa, ho haha ​​le ho etsa lipatlisiso ho fumana hore na thepa ea mefuta e fapaneng ke efe, ho kenyeletsoa litšepe, polasetiki le masela.

Mochini oa ho etsa liteko ke eng?Mochini oa ho etsa liteko ke sesebelisoa se sebelisang matla ho thepa ho fihlela e robeha kapa e senyeha.Mochini o na le mohlala oa teko, o tlanngoeng pakeng tsa li-grips tse peli 'me o tlas'a matla a axial, le sele ea mojaro, e lekanyang matla a sebelisoang ho mohlala.Sele ea mojaro e hokahane le komporo, e tlalehang matla le data ea phalliso ebe e e rala ka graph.

Mochini oa ho etsa liteko o sebetsa joang?E le ho etsa tlhahlobo e tsitsitseng, mohlala oa teko o kenngoa ka har'a lisebelisoa tsa mochine ebe o huloa ka thōko ka lebelo le sa khaotseng.Ha mohlala o ntse o otlolohile, sele ea mojaro e lekanya matla a hlokahalang ho e hula 'me extensometer e lekanya ho falla ha mohlala.Lintlha tsa matla le tsa ho falla li ngotsoe 'me li hlophisitsoe holim'a graph, e leng se bontšang khatello ea khatello ea maikutlo ea thepa.

Melemo ea ho sebelisa mochini oa liteko oa tensile ke ofe?Mechini ea liteko tsa tensile e fana ka tlhaiso-leseling ea bohlokoa mabapi le thepa ea thepa, ho kenyelletsa matla a eona, elasticity le ductility.Lintlha tsena li sebelisoa ho rala le ho etsa lihlahisoa tse bolokehileng, tse tšepahalang, le tse tšoarellang nako e telele.Mechini ea liteko tsa tensile le eona e ka sebelisoa ho lekola boleng ba thepa e tala le lihlahisoa tse feliloeng, le ho tseba mefokolo kapa bofokoli bofe kapa bofe ho thepa.

Mefuta ea mechini ea ho etsa liteko: Ho na le mefuta e 'maloa ea mechini ea tlhahlobo ea matla, ho kenyeletsoa mechini ea tlhahlobo ea bokahohle, mechini ea tlhahlobo ea servo-hydraulic le mechini ea tlhahlobo ea electromechanical.Mechini ea tlhahlobo ea Universal ke mofuta o atileng haholo mme o sebelisetsoa ho lekola lisebelisoa tse fapaneng.Mechini ea tlhahlobo ea servo-hydraulic e sebelisetsoa tlhahlobo e matla le e potlakileng, ha metjhini ea tlhahlobo ea electromechanical e sebelisoa bakeng sa tlhahlobo e tlase le e tlase.

Qetello: Mechini ea liteko tsa tensile ke lisebelisoa tsa bohlokoa tsa ho lekanya thepa ea thepa.Li fana ka tlhahisoleseding ea bohlokoa mabapi le matla, elasticity le ductility ea thepa, e sebelisetsoang ho rala le ho etsa lihlahisoa tse sireletsehileng le tse ka tšeptjoang.Ka mefuta e fapaneng ea mechini ea ho etsa liteko e fumanehang, u ka khetha e loketseng litlhoko tsa hau.
