Elaboration and Experimental Validation of Divers Workload

Using an Ergometer in a Controlled Underwater Environment This thesis presents the development and validation of a weight-based ergometer system for assessing diver workload under controlled and realistic swimming conditions.The aim was to design a test setup that enables divers to swim against adjustableresistance levels corresponding to standardized workload intensities. Understanding diver workload is essentialContinue reading “Elaboration and Experimental Validation of Divers Workload”

Predictive Maintenance for Cableway Rollers

Systematic Concept Evaluation and ExperimentalValidation of a Portable Condition Monitoring Device Background. Unplanned stoppages in cableway roller systems cause significantfinancial losses and material waste in manufacturing environments like NKT inKarlskrona. Current maintenance strategies are mostly reactive or rely on manualinspections, creating a need for practical predictive maintenance solutions. Objectives. The objectives of the thesis areContinue reading “Predictive Maintenance for Cableway Rollers”

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”
