Trapphiss / Stair lift

Rogersson, Leonard, Blom, Erik January 2024 (has links)
Denna kandidatuppsats handlar om framtagandet av en billig, enkel och lättinstallerad trapphiss med syftet att underlätta tillgängligheten i lägenhetshus för personer med begränsad rörlighet på grund av deras nerver och leder. Befintliga trapphissar, AFS 2008:3 och SS-EN 81-40:2020 har analyserats för att sätta krav som har behövts följas under projektets gång. Efter en noggrann utvärdering av olika drivmekanismer valdes kugghjul och kuggstång som den mest lämpliga mekanismen baserat på de satta kraven. Val och dimensionering av komponenter till trapphissen har gjorts med hjälp av beräkningar och är baserade på kraven. En modell, med tillhörande komponenter, har konstruerats med CATIA. Modellen har simulerats både i SimSolid och CATIA varav optimeringar har gjorts utefter simuleringsresultat, vilka visade sig vara delvis godkända. Slutsatserna visar att noggrann planering, design och optimering av produkten har bidragit till att uppnå målet att skapa en anpassningsbar och lättinstallerad trapphiss. / This bachelor thesis is about the creation of a cheap, simple and easily installed stair lift with the purpose of facilitating the availability in an apartment building for people with limited mobility because of their nerves and joints. Existing stairlifts, AFS 2008:3 and SS-EN 81-40:2020 have been analysed to establish requirements that needed to be followed throughout the course of the project. After carefully validating different drive mechanisms, gear and rack were chosen as the most suitable mechanism based on the established requirements. Selection and dimensioning of components for the stair lift was made with the help of calculations and are based on the requirements. A model, along with its associated components, was constructed using CATIA. The model has been simulated using both Simsolid and CATIA, and optimizations were made based on the simulation results, which proved to be partly valid. The conclusions demonstrate that meticulous planning, design and optimisation of the product have contributed to achieving the set goal of creating an adjustable and easily installed stair lift.
