  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. Classification of ultrasonic signals using machine learning to identify optimal frequency for elongation control : Threaded fastening tools

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

    Author : Mazen Bahy; [2022]
    Keywords : Machine Learning; Convolutions Neural Network CNN ; Barker signals; Ultrasonic sensors; Clamp-force; Threaded fastening assembly; Maskininlärning; konvolutionellt neuralt nätverk; Barker-signaler; Ultraljudssensorer; klämkraft; Åtdragningsmontering;

    Abstract : Studying the preload in a screw joint has been the focus of today’s industry. The manufacturer reflects that demand by investigating different opportunities and techniques to develop this area. There are four different ways of controlling the tightening of bolts and joints to achieve the required clamp force that can hold for a specific preload. READ MORE

  4. 3. Screw Joint Analysis in Radio Frequency Filters

    University essay from KTH/Industriell produktion

    Author : Nils Löwhagen; [2022]
    Keywords : Digital filter; Pre-load force; Clamp torque; Release torque; Surface roughness; Thermal shock test; Digitalt filter; Förspänningskraft; Klämvridmoment; Lossdragningsmoment; Ytjämnhet; Termiskt chocktest;

    Abstract : Filter devices are central elements of radio units utilized for modern-day telecommunication. Leakages of radio waves and passive intermodulation are evolving more prominent as the frequency bands become crowded. READ MORE

  5. 4. Design of a Tribometer to Study Friction inThreaded Fastener Interfaces

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Zhan-Jun Lin; [2020]
    Keywords : tribometer; friction coefficient; tightening; pin-on-disc; tribometer; friktionskoefficient; åtdragning av skruvförband; pin-on-disc;

    Abstract : Bolts and nuts are one of most common joining methods since they are simple and low-cost to connect parts. Appropriate clamp force from bolted joint remains resultant joints secured, but higher/lower preload on bolted joint increases risk of the failure of mechanism. READ MORE

  6. 5. Development and Validation of Threaded Fastener Test Rig

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Fredrik Wirström; [2019]
    Keywords : Threaded; Fastener; Joint; Test; Rig; Friction; Bolt; Screw; Thread; Transducer; Sensor; Gauge; Strain;

    Abstract : Threaded fastener is one of the most common ways to join components. Having a method to test threaded fasteners is key when designing a joint and even more a nutrunner. A joint is often tightened by a torque applied on the head. READ MORE
