Razvoj brezžičnega sistema za merjenje torzijskih deformacij gredi

Rihter, Niko (author), Čepon, Gregor (mentor)

Zaključna naloga predstavlja razvoj merilne celice za brezžično merjenje navora gredi. Opisana je teorija nastanka torzije v gredi okroglega prereza in način, kako lahko pretvorimo deformacijo materiala v električni signal, nato pa ga brezžično pošljemo in pretvorimo v obliko, iz katere lahko izluščimo potrebne informacije. V ta namen je bil zasnovan sistem, ki smo ga razdelili v merilni in sprejemni del, oba dela pa povezujeta nRF24L0+ modula, ki skrbita za brezžični prenos podatkov. Izvedli smo preizkus delovanja celice, ovrednotili rezultate in podali predloge za izbolšanje.

• Title: Development of a wireless system for measuring shaft torsional deformations

Abstract

The final thesis presents the development of a measuring cell for wireless shaft torque measurement. The theory of torsion formation in a round cross-section shaft is presented and the way in which we can convert the deformation of a material into an electrical signal. Then we send it wirelessly and convert it into a form from which we can extract the necessary information. For this purpose, a system was designed and divided into a measuring and receiving part. Both parts are connected by nRF24L0+ modules which take care of wireless data transmission. We performed the cell function test, evaluated the results and made suggestions for improvement.
