Plastic Simple Beam Instrumented Pendulum Impact Tester

Isihloli somthelela se-plastic pendulum siyithuluzi lokuhlola ukumelana komthelela wezinto ezingaphansi komthwalo oguquguqukayo. Kuyithuluzi lokuhlola elidingekayo labakhiqizi bezinto ezibonakalayo kanye neminyango yokuhlola ikhwalithi, futhi liyithuluzi lokuhlola elibalulekile lamayunithi ocwaningo lwesayensi ukwenza ucwaningo lwezinto ezibonakalayo.

Izinzuzo Zomkhiqizo:
Ukubukeka kwe-instrumentation (ngokunembile, idijithali) umshini wokuhlola umthelela we-pendulum kulethe izinguquko eziphawulekayo ekuhlolweni komthelela ezicini ezimbili.
Omunye umehluko omkhulu phakathi komshini wokuhlola umthelela we-pendulum onezinsimbi kanye nomshini wokuhlola ojwayelekile i-instrumentation (digitization): okungukuthi, ukulawula, ukuboniswa kwamandla, nokuqoqwa nokucutshungulwa kwejika lomthelela konke kwenziwa kudijithali. Imiphumela yokuhlolwa komthelela ibonwa ngokuboniswa kwesithombe, futhi amajika esikhathi samandla okuthinta, ukuchezuka komthelela njll. kungatholwa;
Okwesibili “ukumiswa kwezindlela zokuhlola umthelela wensimbi”, okubangele ushintsho lwekhwalithi ekuhlolweni komthelela. Lolu shintsho lubonakala ezicini ezilandelayo:
1. Incazelo yamandla omthelela isekelwe encazelweni yomsebenzi owenziwe ngokomzimba: umsebenzi=impoqo×ukususwa, okungukuthi, indawo engaphansi kwejika lokuphambukisa ngamandla isetshenziselwa ukukala;
2. Amapharamitha angu-13 abonisa ukusebenza komthelela wento echazwe ijika lomthelela angu-13:1 uma kuqhathaniswa nepharamitha yamandla omthelela eyodwa kuphela enikezwe indlela yokuhlola umthelela evamile, engakwazi ukuthiwa iwushintsho lwekhwalithi;
3. Phakathi kwamapharamitha wokusebenza angu-13, kukhona amandla angu-4, ukuchezuka okungu-5, namapharamitha angu-4 wamandla. Zikhombisa ngokulandelana izinkomba zokusebenza ze-elasticity yezinto, ipulasitiki kanye nenqubo yokuphuka ngemva kokuba nomthelela, okuwuphawu loshintsho lwekhwalithi ekuhlolweni komthelela;
4. Bona ngeso lengqondo ukuhlolwa komthelela. Ingase futhi ithole ijika lokuphambukisa ngamandla njengokuhlola okuqinile. Ejikeni, singabona ngokubukeka ukuguquguquka kanye nenqubo yokuphuka yesampula yomthelela;

Izici:
1. Ingabonisa ngokuqondile ijika langempela, isikhathi samandla, ukuphambuka kwamandla, isikhathi samandla, ukuchezuka kwamandla, ijika lokuhlaziya namanye amajika.
2. Amandla omthelela abalwa ngokuzenzakalelayo ngokuya nge-engeli yokuphakamisa i-pendulum. 3. Bala amandla amane we-inertial peak force, amandla aphezulu, amandla okuqala okukhula okungazinzile kokuqhekeka, kanye namandla okuphuka ngokusekelwe kumanani akaliwe wenzwa yamandla; ukuchezuka kwe-inertial ephezulu, ukuchezuka ngamandla amakhulu, ukuchezuka kokuqala kokukhula okungazinzile kwe-crack, ukuchezuka kwe-fracture, ukugudluka okuhlanu okuphelele; Imiphumela eyi-14 ehlanganisa amandla anamandla amakhulu, amandla okuqala okukhula kokuqhekeka okungazinzile, amandla okuphuka, amandla amahlanu wamandla aphelele, namandla omthelela. 4. Iqoqo le-engeli lamukela isishumeki sesithombe sikagesi esinembe kakhulu, futhi ukulungiswa kwe-engeli kufika ku-0.045°. Qinisekisa ukunemba kwamandla omthelela wemishini. 5. Idivayisi yokubonisa amandla inezindlela ezimbili zokubonisa amandla, eyodwa isibonisi se-encoder, kanti eyesibili isilinganiso samandla ngenzwa, futhi isofthiwe yekhompiyutha iyabala futhi ibonise. Izindlela ezimbili zalo mshini ziboniswa ndawonye, ​​​​futhi imiphumela ingaqhathaniswa nomunye nomunye, engaqeda ngokuphelele izinkinga ezingenzeka. 6. Amakhasimende angamisa izinzwa zamandla ahlukene ukuze athinte i-blade ngokuvumelana nezidingo zokuhlola. Isibonelo, i-R2 blade ihlangabezana nezindinganiso ze-ISO ne-GB, futhi i-R8 blade ihlangabezana namazinga e-ASTM.
