1. Method Development & Analysis of Seals using FEM
Master-uppsats, KTH/MaskinkonstruktionSammanfattning : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. LÄS MER
2. Open-Circuit-Voltage hysteresis measurement and modelling of LiFePO4 Batteries : Master Thesis Report - 2023
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In a context of an expected increasing use of Lithium-ion batteries in the transportation sector, Volvo AB is developing its own solutions for large electric vehicles. It is then beneficial to reduce the costs, the energy demand and the raw materials demand by improving the battery systems’ performances. LÄS MER
3. Relay settings for frequency derivative protection against islanding : Optimizing RoCoF-Hysteresis and Delay for the Swedish power grid: An investigation of relevant values
M1-uppsats, KTH/Hälsoinformatik och logistikSammanfattning : This report addresses the parameter settings for a protective relay designed to safeguard a 15 kW wind turbine located in Rimbo, Norrtälje municipality, against unintentional islanding. This type of situation arises when distributed energy resources continue to supply local loads, even if the main grid has been unintentionally disconnected. LÄS MER
4. Dynamic Modelling of a Fluidic Muscle with a Comparison of Hysteresis Approaches
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : n recent years, there has been a surge in interest and research into the utilisation of soft actuators within the field of robotics, driven by the novel capabilities of their inherently compliant material. One such actuator is the Pneumatic Artificial Muscle (PAM) which offers a high power-to-mass ratio, compliance, safety, and biological mimicry when compared to their traditional counterparts. LÄS MER
5. Tillståndsövervakning av kullagers friktionsmoment med trådtöjningsgivare
Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknikSammanfattning : Fram tills idag har stor del av kullagers tillståndsövervakning skett genom att analysera vibrationer som ökar i takt med att kullager slits. Tillståndsövervakning av maskinella komponenter är en viktig del för att åstadkomma hög tillgänglighet i maskiner där underhåll kan planeras in först när komponenter är slitna men innan de går sönder.
