  1. 1. Analog mixed signal front-end for Torque signal processing : A theoretical noise analysis and signal-chain evaluation

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jesper Jansson; Wilhelm Nordgren; [2023]
    Nyckelord :Torque sensor; noise analysis; signal processing; analog-to-digital conversion; Momentgivare; brusanalys; signalbehandling; analog-till-digital omvandling;

    Sammanfattning : High precision tightening of nuts and bolts together with traceability are important in many industrial assembly lines. To achieve this the nutrunner needs to accurately measure the torque which is applied to the nut, process the signal and provide the information to the controller that controls the tightening process.

  3. 2. 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

  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. Implications of Analytics and Visualization of Torque Tightening Process Data on Decision Making : An automotive perspective

    Master-uppsats, KTH/Produktionsutveckling

    Författare :Nikhil Thomas; [2023]
    Nyckelord :Torque tightening; Digitalization; Data Analytics; Visualization; Momentåtdragning; Digitalisering; Dataanalys; Visualisering;

    Sammanfattning : In recent years, there is an increased focus on integrating digital technologies in industrial processes, also termed ”Industry 4.0”. Out of the many challenges for the transition, one is to understand how to find useful insights from data collected over large periods of time, predominantly in industrial IT systems. LÄS MER

  7. 5. 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
