I-Plastiki elula iBeam ene-Pendulum Impact Tester

I-instrumented plastic pendulum impact tester sisixhobo sokuvavanya ukuchasana kwempembelelo yezinto phantsi komthwalo oguqukayo. Sisixhobo sovavanyo esiyimfuneko kubenzi bezinto eziphathekayo kunye namasebe okuhlola umgangatho, kwaye sisixhobo esiyimfuneko sokuvavanya kwiiyunithi zophando lwezenzululwazi ukwenza uphando olutsha lwemathiriyeli.

Izinto eziluncedo kwiMveliso:
Inkangeleko yesixhobo (ngokuchanekileyo, idijithali) umatshini wokuvavanya impembelelo ye-pendulum uye wazisa utshintsho olubalulekileyo kuvavanyo lwempembelelo kwimiba emibini.
Omnye umehluko omkhulu phakathi komatshini wokuvavanya impembelelo ye-pendulum kunye nomatshini wokuvavanya oqhelekileyo yi-instrumentation (digitization): oko kukuthi, ulawulo, umboniso wamandla, kunye nokuqokelela kunye nokucubungula i-curve yempembelelo zonke zifakwe kwidijithali. Iziphumo zovavanyo lwempembelelo zibonwa ngomboniso womzobo, kunye neegophe zexesha lamandla empembelelo, ukuphambukiswa kwamandla empembelelo njl.njl.
Okwesibini "kukumiswa kweendlela zokuvavanya impembelelo yezixhobo", okubangele utshintsho olusemgangathweni kuvavanyo lwempembelelo. Olu tshintsho lubonakaliswa kule miba ilandelayo:
1. Inkcazo yamandla empembelelo isekelwe kwinkcazo yomsebenzi womzimba: umsebenzi = ukunyanzeliswa × ukufuduka, oko kukuthi, ummandla ophantsi kwempembelelo yokunyanzeliswa kwe-curve isetyenziselwa ukulinganisa;
2. Iiparamitha ezili-13 ezibonisa ukusebenza kwempembelelo yezinto ezichazwe yigophe lempembelelo yi-13: 1 xa kuthelekiswa nenye kuphela iparamitha yamandla empembelelo enikwe yindlela yovavanyo lwempembelelo eqhelekileyo, engenakuthiwa yinguqu yomgangatho;
3. Phakathi kweeparamitha zokusebenza ezili-13, kukho amandla ama-4, ukuphambuka kwe-5, kunye neeparamitha zamandla ezi-4. Ngokulandelelana babonisa izalathisi zentsebenzo yezinto eziphathekayo, iplastiki kunye nenkqubo yokuqhekeka emva kokuchaphazeleka, okuluphawu lokutshintsha kwekhwalithi kuvavanyo lwempembelelo;
4. Yiba nombono wovavanyo lwempembelelo. Isenokufumana kwakhona igophe lempembelelo yokuphambuka njengovavanyo lwe-tensile. Kwi-curve, sinokubona ngokubonakalayo inkqubo yokuguqulwa kunye nokuphuka kwesampuli yempembelelo;

Iimbonakalo:
1. Iyakwazi ukubonisa ngokuthe ngqo i-curve yasekuqaleni, i-force-time, i-force-deflection, i-energy-time, i-energy-deflection, i-curve yokuhlalutya kunye nezinye iingqungquthela.
2. Amandla empembelelo abalwa ngokuzenzekelayo ngokwe-angle yokuphakamisa i-pendulum. 3. Bala imikhosi emine ye-inertial incopho yamandla, amandla aphezulu, amandla okuqala okukhula okungazinzanga kokuqhekeka, kunye nokwaphulwa kwamandla okusekwe kumaxabiso alinganisiweyo wesivamvo samandla; Incopho yophambuko olungenasiphelo, ukuphambuka kumandla aphezulu, ukuphambuka kokuqala kokukhula okungazinzanga kwe-crack, ukuphambuka koqhekeko, ukufuduswa okuHlanu okupheleleyo; Iziphumo ezili-14 zibandakanya amandla awona mandla aphezulu, amandla okuqala okukhula okungazinzanga kokuqhekeka, amandla okuqhekeka, amandla amahlanu anamandla ewonke, kunye namandla empembelelo. 4. Ingqokelela ye-angle ithatha i-high-precision photoelectric encoder, kwaye isisombululo se-angle sifikelela kwi-0.045 °. Qinisekisa ukuchaneka kwezixhobo zempembelelo yamandla. 5. Isixhobo sokubonisa amandla sineendlela ezimbini zokubonisa amandla, enye yi-encoder display, kwaye okwesibini ngumlinganiselo wamandla yinzwa, kwaye isofthiwe yekhompyutheni ibala kwaye ibonise. Iindlela ezimbini zalo matshini ziboniswa kunye, kwaye iziphumo zinokuthelekiswa kunye nomnye, ezinokuphelisa ngokupheleleyo iingxaki ezinokwenzeka. 6. Abathengi banokuqulunqa ii-sensor zamandla ezahlukeneyo ukuze bachaphazele i-blade ngokweemfuno zovavanyo. Ngokomzekelo, i-R2 blade idibana nemigangatho ye-ISO kunye ne-GB, kwaye i-R8 blade ihlangabezana nemigangatho ye-ASTM.
