The Swedish Defence Materiel Administration, FMV’s, test site in Vidsel, Norrbotten, has access to the largest area for testing and evaluating military aircraft, missiles and unmanned vehicles over land in Europe. The facility has the capacity to create many different types of test enviroments, which are continously developed to meet the customers growing requirements where the main focus is using different types of aerial targets. This project is a thesis for a Master in Mechanical Engineering and Machine Design. The purpose of the project was to develop a new brake system for the aerial tow target, SM3C. The goal of the project was to come up with a concept with enough support to say what, why and how the new concept meets the desired requirements. With a structured and iterative product development process, based on Ulrich & Eppingers theories, the identified needs of the new brake system and data from the existing product resulted in a product specification with quantifiable metrics. From the development process and product specification, the project resulted in a detailed and designed concept that was more standardized, modular and less complex than the existing product with support from theoretical analysis, experiments and simulations of the brake system. / Försvarets Materialverk, FMVs, provplats i Vidsel, Norrbotten, har tillgång till Europas största provområde för test och evaluering av stridsflygplan, robotar och obemannade farkoster över land. Provplatsen kan presentera en mängd olika testmiljöer som kontinuerligt utvecklas för att möta kundernas växande krav där fokus ligger på olika typer av luftmål. Projektet innefattar ett examensarbete för en civilingenjörsutbildning i maskinteknik med syfte att utveckla ett nytt bromssystem till det luftburna släpmålet, SM3C. Målet med projektet var att tillsammans med en funktionsanalys av det befintliga bromsystemet komma fram till ett koncept med tillräckligt underlag som kunde påvisa vad, varför och hur konceptet uppfyller de önskade kraven. Med en strukturerad och iterativ produktutvecklingsprocess, baserad på Ulrich & Eppingers teorier, bearbetades behoven av ett nytt bromssystem tillsammans med analysen av den befintliga produkten vilket gav en kravspecifikation med kvantifierbar data. Utifrån kravspecifikationen och utvecklingsprocessen, resulterade projektet i ett detaljkonstruerat koncept som var mer standardiserat, modulärt och mindre komplext än befintligt system med stöd från utförda analyser, experiment och simuleringar.

Volvo Trucks is the second-largest heavy-duty truck provider in the world. As of now they are working towards fossil free transport solutions. This comes with a fast development pace and an increasing need of being able to verify new and complex assembly processes to ensure an integration of the production of new truck models together with the current vehicles that are being produced.  This project is a master thesis that focuses on improving the quality and verification capabilities of the Pilot Plant at the Volvo Tuve site. The goal of the project is to design and develop a modular transport solution that can be used to move truck chassis at a predefined speed to be able to simulate and perform assembly tasks with the same parameters in the test environment as in the factory process along the driven line. The design was developed using the product development process described by Ulrich et al., 2020, with slight modification. The resulting design is able to move the truck chassis at the requested predefined speeds that are possible on the driven line in the factory. This solution gives Volvo the ability to perform simulations of specific and critical assembly steps, potentially resulting in fewer failures during production ramp-up of their new truck models.  Calculations were made to in order to verify the strength and functionality of the design.
