  1. 1. Formula Student Car Stability

    Kandidat-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Oliver Belfiore; [2023]
    Nyckelord :Racing; Car; Vehicle; dynamics; vehicle dynamics; Technology and Engineering;

    Sammanfattning : This thesis investigates the impact of varying passive components on the stability of a Formula Student race car. The study was conducted using a 7-post model and a lateral model, both of which were derived using Lagrangian methods and state-space modelling techniques. These models were then validated and adjusted using logged data. LÄS MER

  3. 2. Evaluation of IMO second-generation intact stability criteria and examination of different fishing vessel designs to dead ship condition and excessive acceleration failure mode

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Pavlos Liatsis; [2023]
    Nyckelord :Ship Design; Second Generation Intact Stability Criteria; Excessive Acceleration; Fishing Vessels; Skeppsdesign; andra generationens intakt stabilitetskriterier; kraftiga acceleration; fiskefartygsskrovs;

    Sammanfattning : The main objective of this project is to investigate the applicability of the IMO second-generation intact stability criteria in enhancing the process of designing fishing vessels, which often face stability challenges due to their narrow hulls and harsh operating environments. The study involves analyzing the impact of these criteria, specifically focusing on dead ship conditions and Level 1 and Level 2 excessive acceleration criteria, on the design of three fishing vessels.

  4. 3. Kritiska vippningslaster för kompositbalkar/lättbalkar av trä

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Jemy Abdalnour; Mohamed Ibrahim Abdirahman; [2023]
    Nyckelord :;

    Sammanfattning : This thesis has focused on the calculation of critical loads for lateral torsional buckling forthree selected wood-based composite beams with varying heights based on the availableMasonite Beams standard range. The main objective has been to investigate and compare ahand calculation model with the recommended method in Eurocode 5, as well as comparethem with results from finite element analysis. LÄS MER

  5. 4. Jämförelse mellan grundläggningsmetoder för lera med begränsat djup

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Isak Ekström; Taulant Lutfiu; [2023]
    Nyckelord :Short piles; land excavation; environment; soil replacement; Grundläggningsmetoder; kostnad; korta pålar; miljö; utskiftning;

    Sammanfattning : This thesis compares foundation methods for buildings on low-strength, limited-depth soil. The study focuses on soil replacement and piling, specifically concrete and steel piles. The studyaims to answer the key questions about the possibility to use short piles on limited depth, cost-efficiency, and environmental impact of these methods. LÄS MER

  7. 5. Holistic embedding of equivalent conicity in wheelset maintenance

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Philipp Linzbichler; [2023]
    Nyckelord :Railway Operation; Equivalent Conicity; Wheelset Maintenance; Smart Maintenance; Data Analysis; Järnvägsdrift; Ekvivalent Konicitet; Hjulset Underhåll; Smart Underhåll; Dataanalys;

    Sammanfattning : With continuing digitization of railways an increasing number of data is recorded but particularly in operation advanced analysis tends to be partially rudimentary. Yet, it is essential to implement sophisticated processing for all records in order to develop more purposeful and predictive vehicle maintenance strategies that adhere to the increasing requirements imposed by the homologation.
