EDUCATIONAL BENDING AND TORSION TESTING DEVICE

U završnom radu metodičkim pristupom, izradom liste želja i zahtjeva, apstrahiranjem, izradom ukupne funkcionalne strukture proizvoda te parcijalnih rješenja funkcioniranja i rada naprave izdvojene su dvije verzije edukacijske naprave za ispitivanje materijala na savijanje i uvijanje. Uz dimenzioniranje ispitnih epruveta napravljeni su proračuni čvrstoće i krutosti ispitnih uzoraka te su po njima dimenzionirana naprava te nacrti obje varijante, nakon toga na temelju tehničkog i ekonomskog vrednovanja svake zasebno odabrana je bolja varijanta. Za odabranu varijantu izvršena je detaljna konstrukcijska razrada, izrada tehničke dokumentacije te proračuni.In the final work with methodical approach, drawing of wish and request list, abstraction, manufacturing of the total functional structure of the product and the partial solutions of the functioning and operation of the device, two versions of the educational device for testing bending and twisting materials were separated. Sizing of the test tubes was done by calculating the strength and stiffness of the test samples and by means of their dimensioned devices and the designs of both variants, after that on the basis of technical and economic evaluation each separately selected a better variant. For the selected variant, detailed constructional design, technical documentation and calculations were performed
