  1. 1. Implementing Kalman Filtering Algorithms for Estimating Clamp Force on a Test Rig : Testing the Power and Limitations of Unscented Kalman Filter-based Estimations

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Tim Naser; [2023]
    Nyckelord :Clamping Froce; Kalman Filtering; Unscented Kalman Filtering; Tightening; Consequence of User Errors During Tightening; Velocity Profiles; Klämkraft; Kalman Filtrering; Unscented Kalman Filtrering; Åtdragning; Konsekvens av Användarfel Under Åtdragning; Hastightersprofiler.;

    Sammanfattning : his study explores clamp force estimation using Unscented Kalman Filtering (UKF) in torque-controlled tightening scenarios with various velocity profiles. Previous research has explored the impact of velocity levels on target torque and clamping force, but only using hand-held tools. LÄS MER

  3. 2. Evaluation of a Test Rig to Determine the Need For Human Operators in Ergonomic Testing of Pistol Grip Power Tools

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Felix Ekman; Axel Sernelin; [2023]
    Nyckelord :;

    Sammanfattning : Handheld power tools are found in many different manufacturing processes, everywhere from miniature screw joints in cell phones to safety-critical joints in automotive vehicles. The tools are often used for many consecutive hours which emphasizes the need for good ergonomics to ensure the safety of the operators. LÄS MER

  4. 3. Comparative analysis of contact and non-contact method for determining the natural frequencies of a bolted joint

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Malin Dyberg; Elvira Troillet; [2023]
    Nyckelord :;

    Sammanfattning : To ensure high assembly quality of components, a proper clamping force in bolted joints is essential. The existing tightening technology rely on torque and angle; however, this thesis proposes a method for obtaining the clamping force of a bolted joint based on measuring the natural frequencies.

  5. 4. Electrical transition of the automotive industry : A case study of a Swedish automotive tool manufacturer

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Oscar Brönmark Riex; Jakob Holm Bjelke; [2023]
    Nyckelord :Market analysis; Automotive industry; Manufacturing; Powertrain; EV; ICE; Marknadsanalys; Fordonsindustrin; Tillverkning; Powertrain; EV; ICE;

    Sammanfattning : The need for sustainability solutions requires a shift towards renewable energy and less dependence on fossil fuels, exemplified by the EU’s Green Deal targeting zero greenhouse gas emissions by 2055. This shift creates uncertainties in the global economy, and it recently sparked the automotive industry’s move from the internal combustion engine (ICE) to the electric vehicle (EV). LÄS MER

  7. 5. A Comparative Study of Machine Learning Algorithms for Angular Position Estimation in Assembly Tools

    Master-uppsats, KTH/Matematisk statistik

    Författare :Henrik Fagerlund; [2023]
    Nyckelord :applied mathematics; circular fully convolutional network; nearest neighbour method; power tools; threaded fasteners; neural network; machine learning; convolution; tillämpad matematik; cirkulärt faltningsnätverk; närmaste granne-metod; elverktyg; skruvförband; neuralt nätverk; maskininlärning; faltning;

    Sammanfattning : The threaded fastener is by far the most common method for securing components together and plays a significant role in determining the quality of a product. Atlas Copco offers industrial tools for tightening these fasteners, which are today suffering from errors in the applied torque. LÄS MER
