  1. 11. Characterization of NOx sensor performance under oscillating pressure conditions

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

    Författare :Álvaro López Méndez; [2023]
    Nyckelord :NOx sensors; engine – out heavy duty vehicle conditions; oscillating pressure; test rig testing; NOx-sensorer; motor – ut tunga fordonsförhållanden; oscillerande tryck; testriggtestning;

    Sammanfattning : The NOx sensor is essential in the modern after-treatment system. Due to the introduction of regulations from the US, it is necessary to investigate how these sensors operate in conditions of pulsating pressures generated engine - out, after the turbocharger. LÄS MER

  3. 12. 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. 13. 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

    Sammanfattning : In the manufacturing industry, product quality assurance is important to ensure customer safety and product quality. The thesis is based on problems identified with calibration of ultrasonic sensors used in quality assurance of rear shafts for trucks and buses. LÄS MER

  7. 15. Experimental Investigation of High Prandtl Number Flow in Additive Manufactured Channels

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

    Författare :LINDA YANG; [2023]
    Nyckelord :Additive manufacturing; Heat transfer; Darcy friction factor; Nusselt number; Minichannel.; Friformsframställning; Värmeöverföring; Darcy friction factor; Nusselt number; Minikanal.;

    Sammanfattning : Additive manufacturing (AM) rapidly evolves and expands into new industries dueto its great design freedom and time savings. Injection molding is an excellentindustry where AM can help reduce cooling time by printing complex coolingchannels for more effective and uniform cooling. LÄS MER
