Zasnova zaznavala za merjenje notranjih sil in momentov v nosilcu

Novak, Benjamin (author), Čepon, Gregor (mentor)

Merjenje notranjih sil in momentov je veliko bolj zahtevno kot analitična pridobitev le-teh. Različna merilna zaznavala, izkoriščajo različne principe za posredno merjenje notranjih sil in momentov. Notranje količine smo merili prek deformacij z uporovnimi merilnimi lističi. Rezultate meritev smo obdelali v LabVIEW, da smo prišli do upogibnega momenta in notranje osne sile. Notranje momente smo uspešno v realnem času prikazovali na računalniku.

• Title: Development of sensor for measuring the internal forces and moments in beam

Abstract

Measuring the internal forces and moments is more difficult than analytically calculating them. Different measuring devices, use different principles for indirect measurement of internal forces and moments. Internal forces and moments were measured indirectly through deformation with strain gauges. Results of measurements were processed in LabVIEW, so we could see bending moment and axial force, Internal moments were succesfully shown in real time on computer.
