  1. 1. Adaptive Systems to Reduce the Material Cost of Structures

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Erik Lundin; [2022]
    Nyckelord :Adaptive; structure; material economy.; Technology and Engineering;

    Sammanfattning : Adaptive structures adapt to the changing circumstances in their environment using sensors and actuators, they may for example change their shape to be optimised for a specific load case when that load case is present. The building industry need to reduce its climate impact, low-carbon solutions are in demand. LÄS MER

  3. 2. Modelling of contacts in Adams flex bodies using Mamba

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Shashwat Joshi; [2021]
    Nyckelord :Contact simulation; Mamba; Joint Interface Modes; Leaf spring modelling; Frame-subframe contact; ODS analysis; PSD; Kontaktsimulering; Mamba; gemensamma gränssnittslägen Joint Interface Modes ; bladfjädermodellering; ram-subramkontakt; ODS analys; PSD;

    Sammanfattning : Simulations are a powerful tool used to reduce development time and cost in the vehicle industry. However, the models used in simulations are simplifications of reality, and there are commonly contradicting requirements between accuracy and computational efficiency. LÄS MER

  4. 3. Numerical study of the effect of thermal ice loads on concrete dams

    Master-uppsats, KTH/Betongbyggnad

    Författare :Imal Zuwak; Wasseem Kordoghly; [2020]
    Nyckelord :Arch dam; Buttress dam; Concrete; Finite element analysis; Ice load; Valvdamm; Lamelldamm; Betong; Finit elementanalys; Islast;

    Sammanfattning : It is essential to understand the mechanics of ice load and how it affects concrete dams located in a cold climate, such as Sweden, where the temperature becomes sufficiently cold to freeze the surface of the reservoir. The purpose of this thesis is to study ice load distribution along concrete dams, and its response during the application of an ice load. LÄS MER

  5. 4. Gripper Tool Designed for a Surgical Collaborative Robot

    Uppsats för yrkesexamina på avancerad nivå, KTH/Medicinteknik och hälsosystem

    Författare :Emma Andersson; [2019]
    Nyckelord :Medical robotics; Surgical Suturing; Gripper Tool; Design Methodology; Double Diamond Design process; Medicinskrobotik; Kirurgisksuturering; Gripdon; Design metodik; Double Diamond Design-process;

    Sammanfattning : In surgery, suturing is the use of needle and thread to join cut and/or damaged anatomical structures together. This repair strategy is highly versatile and is universal for all types of surgery as the goal is to restore, repair or improve function and/or appearance. LÄS MER

  7. 5. Spatial vibration measurements : operating deflection analysis on the example of a plate compactor

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Adrian Potarowicz; Seyed Mazdak Hosseini Moghadam; [2018]
    Nyckelord :Reversible Compactor; Mechanical Vibration; Signal Processing; Power Spectrum estimator; Power Spectral Density estimator; Operating Deflection Shape;

    Sammanfattning : The operating motion of a ground compactor uses high power vibrations to improve mechanical properties of a compacted ground. This motion gives a good base for the vibration analysis with an aid of Signal Processing. In this thesis, the motion of a bottom plate in a compactor is of the main interest. LÄS MER
