    Tlhaloso ea 1.Material General

    Constantanke motsoako oa koporo-nickel hape o tsejoa e leEureka,Tsoela pele, leSekepe. Hangata e na le 55% koporo le 45% nickel. Tšobotsi ea eona e ka sehloohong ke resistivity ea eona, e leng kamehla ho feta mefuta e mengata ea mocheso. Li-alloys tse ling tse nang le li-coefficients tse tšoanang tsa mocheso o tlase lia tsebahala, joalo ka manganin (Cu86Mn12Ni2).

     

    Bakeng sa tekanyo ea mefuta e meholo haholo, 5% (50 000 microstrian) kapa ka holimo, annealed constantan (P alloy) ke lisebelisoa tsa marang-rang tse khethiloeng ka tloaelo. Constantan ka mokhoa ona o monate haholoductile; 'me, ka li-gauge tsa bolelele ba lisenthimithara tse 0.125 (3.2 mm) le ho feta, li ka hatelloa ho>20%. Leha ho le joalo, ho lokela ho hopoloa hore tlas'a mathata a phahameng a cyclic alloy ea P e tla bontša phetoho e sa feleng ea ho hanyetsa ka potoloho e 'ngoe le e' ngoe, 'me e etse hore ho be le phetoho e tšoanang.zeroho fetoha ha sekhahla sa khatello. Ka lebaka la tšobotsi ena, le tšekamelo ea ho hloleha ha marang-rang pele ho nako ka ho tsitsisa khafetsa, P alloy ha e khothalletsoe bakeng sa ts'ebetso ea cyclic strain. P alloy e fumaneha ka linomoro tsa STC tsa 08 le 40 bakeng sa tšebeliso ea litšepe le polasetiki, ka ho latellana.

    Liliba tse otlolohileng tsa tanka ea Stuart

    Khatello e hlaha ka har'a sesebelisoa sa molumo o mennoeng.

    The torsion bar e sothehileng tlas'a mojaro

    Lekhasi le hlaha terakeng
    Li-Spring li ka aroloa ho latela hore na matla a boima a sebelisoa joang ho tsona:

    Tension / extension spring - selemo se etselitsoe ho sebetsa ka mojaro oa tsitsipano, kahoo selemo se otlolla ha mojaro o sebelisoa ho eona.
    Compression spring - e etselitsoe ho sebetsa ka mojaro oa khatello, kahoo selemo se ntse se khutsufala ha mojaro o sebelisoa ho eona.
    Selemo sa torsion - ho fapana le mefuta e ka holimo eo mojaro e leng matla a axial, mojaro o sebelisoang ho torsion spring ke torque kapa matla a sothehileng, 'me qetello ea selemo e potoloha ka lehlakoreng ha mojaro o sebelisoa.
    Nako eohle ea selemo - mojaro o tšehetsoeng o lula o tšoana nakong eohle ea ho kheloha.
    Ho feto-fetoha ha selemo - ho hanyetsa ha coil ho laela ho fapana nakong ea khatello.
    Ho satalla ho feto-fetohang selemo - ho hanyetsa ha coil ho laela ho ka fetoha ka mokhoa o fapaneng ka mohlala ka tsamaiso ea taolo, mefuta e meng ea liliba tsena le eona e fapana bolelele ba eona ka hona e fana ka bokhoni ba ho sebetsa.
    Li ka boela tsa aroloa ho latela sebōpeho sa tsona:

    Flat spring - mofuta ona o entsoe ka tšepe e sephara ea selemo.
    Setsi sa selemo se entsoeng ka mochine - mofuta ona oa selemo o etsoa ka mochine oa bar o nang le lathe le / kapa opereishene ea ho sila ho e-na le ts'ebetso ea ho kopanya. Kaha e entsoe ka mochine, selemo se ka 'na sa kenyelletsa likarolo ho phaella ho ntho ea elastic. Liliba tse entsoeng ka mochini li ka etsoa maemong a tloaelehileng a boima ba khatello / katoloso, torsion, jj.
    Selemo sa serpentine - zig-zag ea terata e teteaneng - hangata e sebelisoa ho upholstery / thepa ea morao-rao.
