Topology Optimization as Design Support for Temporary Cable Support Holder
Cable Management During Transport within Production Facility This thesis addresses the issue of transporting cables attached to a pump throughout the manufacturing process, from assembly to painting and packaging, with a solution suitable for a wide range of pumps with alternating sizes, shapes, weights, and suspension systems. In order to generate a fully functional cableContinue reading “Topology Optimization as Design Support for Temporary Cable Support Holder”
Automation av Hantering av Polbultkomplett
Batteritillverkare Saft AB i Oskarshamn har under det senaste året börjat en resa mot ökad automation för att bli mer konkurrenskraftiga, men även reducera repetitiva arbetsuppgifter för att förbättra ergonomin. De har arbetat fram en tydlig industriell vision som sträcker sig till år 2040. Visionen går under arbetsnamnet ”No Touch!” där målbilden är att haContinue reading “Automation av Hantering av Polbultkomplett”
Guiding a continuous sheet through multiple rollers
Tail threading is the process of guiding a continuous sheet through multiple rollers. It is a critical step in paper, board, and textile production, especially after a break or during startup. This thesis investigates the development of improved methods for tail threading in flooring mat production, which is heavier compared to paper and textile production,Continue reading “Guiding a continuous sheet through multiple rollers”
High-frequency radar imaging
High-frequency radar imaging using Synthetic Aperture Radar (SAR) technology has significant potential for non-destructive testing and quality control in industrial applications, such as inspecting High Voltage Direct Current (HVDC) cables during manufacturing. This thesis develops and verifies a calibration procedure designed to accurately determine the Phase Centre (PC) of an FMCW radar antenna mounted onContinue reading “High-frequency radar imaging”
Development of Modular Frames Intended For Sealing Cables
When highly customer specific and specialized products needs quick and easy changes it might produce consequences which affects both the producer and customer negatively.A modular product could ease the financial burden and shorten increasedtime in production by offering a product which can be refined by a reseller close to the customer or by the customerContinue reading “Development of Modular Frames Intended For Sealing Cables”
Adaptive Designs for Maritime Environments
Background: Saab, a Swedish defense and security firm, specializes in aerospace, defense, and maritime technologies. Challenges with customized mounts for naval systems hinder maintenance efficiency and cost-effectiveness. Developing standardized mounts could optimize operations, reduce costs, and improve readiness. Corrosion threatens structures, and reducing a vessel’s magnetic field signature enhances safety by lowering detection risk. Ship vibrationsContinue reading “Adaptive Designs for Maritime Environments”
Test Method for Volume-resistivity Measurements on High Voltage Cables
Introduktion. En del av den standardiserade testproceduren för högspänningskablar är att mäta volymresistiviteten på de olika halvledande skikten. Behovet av förbättring har uppstått på grund av den ökade testfrekvensen, vilket är en följd av den senaste utökningen av kabelproduktionen vid NKT i Karlskrona. Syfte. Syftena med detta masterarbete är först att ta reda på vilka behovContinue reading “Test Method for Volume-resistivity Measurements on High Voltage Cables”
Simulations for developing new parts
The automotive industry is reliant on accurate finite element simulations for developing new parts or machines and to achieve this, accurate material models are essential. Material cards contain input about the material model, and are significant; however, time-consuming to calibrate with traditional methods. Therefore a newer method involving Machine Learning (ML) and Feed-Forward Neural NetworksContinue reading “Simulations for developing new parts”
Cables through the cableways
The work is based on a problem at the company NKT HV Cables AB, Karlskrona. NKT manufactures high-voltage cables which are pulled through complex ableways. The cables are stiff and difficult to bend, which results in them getting stuck in the cableways. In some parts of the factory, one cable will push another cable. ThisContinue reading “Cables through the cableways”
