  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

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Tim Naser; [2023]
    Keywords : 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.;

    Abstract : 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. READ MORE

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

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Malin Dyberg; Elvira Troillet; [2023]
    Keywords : ;

    Abstract : 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.

  4. 3. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Olivia Johansson; [2023]
    Keywords : Performance; Cross-sectional geometry; Computational fluid dynamics;

    Abstract : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. READ MORE

  5. 4. Test Rig Development for Real Time Clamping Force Estimation in Threaded Tightenings with Implemented Extended Kalman Filtering

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Annie Farell; [2023]
    Keywords : Clamping force; Threaded Fastener; Extended Kalman Filtering; Test Rig Development; Real Time Estimation; Sensor Placement.; Klämkraft; gängad fästelement; utökad Kalman filtrering; testrigsutveckling; estimering i realtid; sensorplacering.;

    Abstract : The clamping force between the components during bolt tightening is of great interest, and it has been the focus of developing new tightening techniques for a long time. Today there is no easy or practical method to directly measure the clamping force in a typical production situation. READ MORE

  6. 5. Improvement and verification of a pin-on-disc tribometer with variable speed and load

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Valentine Lin; [2023]
    Keywords : tribometer; friction; tribometer; friktion;

    Abstract : The use of threaded fasteners can be found throughout the manufacturing industry due to their simplicity. When tightening a threaded fastener, the goal is to reach a desired clamping force. However, the clamping force is not directly measurable in production environments and the tightening torque is instead used to estimate the clamping force. READ MORE
