V okviru magistrske naloge smo izdelali dva unikatna načina merjenja navora kolesarjev, ki uporabljata meritev navora prek meritve navora v gonilu z uporabo merilnih lističev oz. induktivnih senzorjev. Raziskali smo tudi obstoječe rešitve na trgu in opisali njihove prednosti in slabosti. Podali smo pregled literature in razdelali pogon električnega kolesa po principu pedelec. Namen raziskovanja je bil razviti merilnik navora kolesarja, ki je izveden brez torzijskega cilindra in je dovolj robusten, poceni in natančen za uporabo vodenja kolesa tipa pedelec po navoru. Pred izdelavo prototipov smo te simulirali v modelirnem programskem orodju Solidworks z uporabo metode končnih elementov. Cilj naloge – razviti novi način merjenja navora, ki ga proizvaja uporabnik na pedala kolesa – smo uspešno izvedli. Potrditev smo podali v obliki analize ter simulacijskih in eksperimentalnih rezultatov. The thesis describes research and development of two unique methods of measuring torque that is provided by the user of the bicycle. In order to get an overview of existing solutions, we studied the existing solutions on the market and described their strengths and weaknesses, thereby describing the current state-of-the-art. The purpose of the research was to develop a torque sensor that needs no torsion cylinder and is sufficiently robust, cheap and accurate for the use for control of electric bicycle type pedelec. Before the prototypes were manufactured, we used modelling software tool Solidworks and simulated prototypes using the finite element method. The stated objective, to develop a new way of measuring the torque produced by the user on the pedals on the bike, has been achieved. The proof was presented in the form of simulation and experimental results. |
