1. Zokolola mphamvu zaflange
Ndi zokolola malire a zitsulo zakuthupi pamene zokolola chodabwitsa zimachitika, ndiye kuti, maganizo kukana microplastic mapindikidwe. Kwa zipangizo zachitsulo zopanda chodziwika bwino zokolola, malire a zokolola amatanthauzidwa ngati mtengo wopanikizika wa 0,2% wotsalira mapindikidwe, omwe amatchedwa malire a zokolola zovomerezeka kapena mphamvu zokolola.
Mphamvu yakunja yokulirapo kuposa mphamvu ya zokolola ipangitsa kuti zigawozo zikhale zosavomerezeka komanso zosasinthika. Ngati malire a zokolola zachitsulo chochepa cha carbon ndi 207MPa, pamene chachikulu kuposa malire awa pansi pa mphamvu zakunja, mbali zidzatulutsa mapindikidwe okhazikika, osachepera izi, zigawo zidzabwezeretsa maonekedwe oyambirira.
(1) Kwa zipangizo zomwe zimakhala ndi zokolola zoonekeratu, mphamvu zokolola ndizopanikizika pa zokolola (mtengo wapatali);
(2) Kwa zipangizo zopanda zokolola zoonekeratu, kupsinjika maganizo pamene kupatuka kwa malire a mgwirizano pakati pa kupsinjika maganizo ndi kupsinjika kumafika pamtengo wodziwika (nthawi zambiri 0.2% ya mtunda woyambirira). Nthawi zambiri amagwiritsidwa ntchito poyesa zida zamakina ndi makina azinthu zolimba, ndipo ndiye malire enieni ogwiritsira ntchito zinthu. Chifukwa mu kupsinjika maganizo kumadutsa malire a zokolola zakuthupi pambuyo pa khosi, kupsyinjika kumawonjezeka, kotero kuti kuwonongeka kwa zinthu, sikungagwiritsidwe ntchito moyenera. Pamene kupsinjika kumadutsa malire otanuka ndikulowa mugawo la zokolola, mapindikidwe amawonjezeka mofulumira, zomwe zimapanga osati zotanuka komanso zowonongeka pang'ono za pulasitiki. Kupsyinjika kukafika pa B, kupsyinjika kwa pulasitiki kumawonjezeka kwambiri ndipo kupsinjika maganizo kumasinthasintha pang'ono, komwe kumatchedwa zokolola. Kupanikizika kwakukulu ndi kupsinjika kochepa pa siteji iyi kumatchedwa mfundo yokolola yapamwamba komanso yotsika mtengo motsatira. Popeza mtengo wa zokolola zotsika ndizokhazikika, zimatchedwa mfundo yokolola kapena mphamvu zokolola (ReL kapena Rp0.2) monga ndondomeko ya kukana zinthu.
Ena zitsulo (monga mkulu mpweya zitsulo) popanda chodziwikiratu zokolola chodabwitsa, kawirikawiri ndi zochitika za kufufuza mapindikidwe pulasitiki (0,2%) wa nkhawa monga zokolola mphamvu zitsulo, lodziwika kuti zovomerezeka zokolola mphamvu.
2. Kutsimikiza kwaflangeperekani mphamvu
The anatchula sanali proportional elongation mphamvu kapena kutchulidwa yotsalira elongation nkhawa ayenera kuyeza kwa zipangizo zitsulo popanda zoonekeratu zokolola chodabwitsa, pamene mphamvu zokolola, chapamwamba zokolola mphamvu ndi mphamvu m'munsi zokolola akhoza kuyeza kwa zitsulo zipangizo ndi zoonekeratu zokolola chodabwitsa. Nthawi zambiri, mphamvu zokolola zokha zimayesedwa.
3. flangezokolola mphamvu muyezo
(1) Kupsyinjika kwapamwamba kwambiri pamlingo wofanana ndi malire-kupanikizika kwapakati, komwe kumagwirizana ndi mgwirizano wa mzere, nthawi zambiri amaimiridwa ndi σ P padziko lapansi. Pamene kupsinjika kumadutsa σ P, zinthuzo zimaonedwa kuti ndi zokolola. Pali milingo itatu yomwe imagwiritsidwa ntchito nthawi zambiri pakumanga:
(2) Elastic malire Kupsyinjika pazipita kuti zakuthupi angathe kuchira bwinobwino pambuyo kutsitsa pambuyo Mumakonda, kutenga palibe yotsalira mapindikidwe okhazikika monga muyezo. Padziko lonse lapansi, nthawi zambiri amawonetsedwa ngati ReL. Nkhaniyi imatengedwa kuti ikupereka pamene kupsinjika kumaposa ReL.
(3) Mphamvu zokolola zimakhazikika pakusintha kotsalira. Mwachitsanzo, 0,2% yotsalira deformation stress nthawi zambiri amagwiritsidwa ntchito ngati mphamvu zokolola, ndipo chizindikiro ndi Rp0.2.
4. Zomwe zimakhudza zokolola mphamvu zaflange
(1) Zinthu zamkati ndi: kuphatikiza, kulinganiza, kapangidwe kake, chilengedwe cha atomiki.
(2) Zinthu zakunja zimaphatikizapo kutentha, kupsinjika maganizo ndi kupsinjika maganizo.
φ ndi gawo lonse, limatanthawuza kukula kwa mapaipi ndi chigongono, chitsulo ndi zinthu zina, tinganenenso kuti ndi m'mimba mwake, monga φ 609.6mm amatanthauza m'mimba mwake 609.6mm.
