Rotationssystem till väggfixtur

Sammanfattning: This bachelor thesis deals with the development process for a design proposal on a rotation system. The work was performed on behalf of Husmuttern AB, whom needs a rotation system to rotate wall fixtures in the company´s future modular house factories. The work has been carried out with an iterative product development methodology that both addresses internal requirements of the company and external requirements from relevant regulations. The work´s imminent problem formulation is; how to develop a rotation system while ensuring that the construction meets the internal requirements from Humuttern AB and external regulations from the Swedish work environment authority regarding load ergonomics and machines. The focus in this work has, besides taking into account ergonomics and security, been to produce a concrete proposal that is to some extent close to manufacturing. This implies that standard components and standard dimensions of materials are used. As a validation of the developed design, FEM analyzes (Finite element method) were applied in SolidWorks where safety factors, stress distributions and deformations could be investigated for the stresses that might arise. The work could be completed within the deadline and delivered what the delimitations specified. The result is a rotation system that will allow ergonomic and safe operation. The work is delivered in the form of this report, which includes the described work process, calculations, drawing documentation, risk analysis and user description of the rotation system's workflow.
