  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. Evaluation of Numerically Developed Models of an ECB for Estimating the Braking Torque on the SkiCrosser

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

    Author : Filip Andersson; William Marin; [2023]
    Keywords : ;

    Abstract : Cross-country skiing is a popular method of exercising that builds strength, stamina and engages the entire body. As cross-country skiing requires snow to be present, it is typically only performed during the winter, resulting in a rather limited way of exercising. READ MORE

  4. 3. Usage of digital twin in order to predict temperature within a thermic test rig

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Malinda Blomqvist; [2022]
    Keywords : Digital Twin; Digital Model; Temperature calibration; Thermal platform; Error modeling; Digital Twin; Digital Model; Värmekalibrering; Termisk platform; Felmodellering;

    Abstract : Many people suffer from diabetes and as a result of the disease, circulatory issues in feet are common. To find such issues at an early stage, Vistafeet were developing a product that measures the temperature in feet. READ MORE

  5. 4. Design of a wheel rig for studded tire wear and aerosol studies

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

    Author : Weizhen Jiang; [2021]
    Keywords : studded tire; wear and aerosol; test rig; dubbdäck; slitage och aerosol; testrigg;

    Abstract : Studded tires are widely used in Nordic areas like Sweden for its good road-gripping performance on icy roads. However, the pavement wear and aerosol caused by studded tires become big concerns considering the usage of studded tires. Studies are carried to quantify the wear and aerosol generated during the process. READ MORE

  6. 5. Design and validation of the control systemfor a Pin-on-Disc Machine

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

    Author : SIMON CALMINDER; JONAS XU; [2021]
    Keywords : Pin-on-Disc; Tribometer; Model; PID; Control; Pinne-skiva; Tribometer; Modell; PID; Reglersystem;

    Abstract : The friction between the under-head of a bolt and the mounting surface affects the necessary torque from a tightening tool. To study the friction behaviour during a highly dynamic tightening process, a Pin-on-Disc testrig has been developed. READ MORE
