Framtagning och optimering av en paddelsensor / Manufacture and optimisation of a paddle sensor

Mahmutovic, Adnan, Micheal, Nahome January 2020 (has links)
Syftet med detta projekt var att skapa en paddlingssensor vilket mäter paddlingskrafteni flera olika riktningar. Detta uppnås genom att skapa en sensor vars kopplingsschema är i enlighet med en wheatstonebrygga och två trådtöjningsgivare som placeras i strategiskt valda positioner. Dessa positioner tillåter sensorn att mäta flera krafter i olika riktningar. Jämfört med tidigare sensorer som endast mäter spänningsskillnaden i en riktning med endast en givare. Trådtöjningsgivarnas positionering utvärderades samt den optimala positioneringen. Sensorn som konstruerades kunde registrera spänningsförändringar som var proportionella till en pålagd vikt. En tydlig linjär korrelation observerades mellan viktökningen och spänningsförändringen. / The purpose of this project was to construct a paddle sensor that has the ability to measure the paddle force in multiple different directions. This can be attained by creating a sensor where the circuitry is in accordance with a wheatstonebridge and strain gauges are strategically placed on predetermined positions. These positions allow the sensor to be able to measure the force in different directions. The positions of the strain gauges were evaluated, and the most optimal placement was chosen. The created sensor was able to register voltage changes which were proportional to an added weight. As the weight increased so did the voltage changes and a clear linear correlation was observed.
