1	Bakhjulsupphängning, fyrhjuling Andersson, Markus, Åberg, Eric January 2007 (has links) <p>Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction. The company where interested in the project and could see themselves proceeding with the work in the future. We helped the company to find interest for computer aided simulation in collaboration with structural strength analysis, which they would like to engage in. The project has given us a larger knowledge in the choices of construction and structural strength analysis as well as experience working with computer aided construction tools.</p> Fyrhjuling ATV Bärarmar Highland Hållfasthet FEM SimDesigner Catia MSC Dassault A-armar Simulation Tvärsnitt Motorcykel Quad Terräng Viktoptimering Finita element metoden

3	Náhrada šroubového spoje dílců světlometu plastovým trnem / Replacement of headlamp parts screw fixation by a plastic nail Lysa, Bohuslav January 2010 (has links) The master thesis covers several issues linked to a substitution of headlamp screw fixation by a plastic nail. The thesis includes an analysis of the headlamp technology, including description of the prescribed durability tests. On the basis of the analysis some new designs of plastic nails are proposed, consistent with characteristics of plastic materials. Selected outcomes of the analysis have been tested as prototypes and verified with Finite Elements Method in SimDesigner including 3D modeling capabilities provided by the Catia V5. The feasibility study regarding a casting form of the new design of plastic nails and technical economic valuation for contingent assembly mounting is included in the thesis.
