  1. 1. A Comparative Study of Machine Learning Algorithms for Angular Position Estimation in Assembly Tools

    University essay from KTH/Matematisk statistik

    Author : Henrik Fagerlund; [2023]
    Keywords : applied mathematics; circular fully convolutional network; nearest neighbour method; power tools; threaded fasteners; neural network; machine learning; convolution; tillämpad matematik; cirkulärt faltningsnätverk; närmaste granne-metod; elverktyg; skruvförband; neuralt nätverk; maskininlärning; faltning;

    Abstract : The threaded fastener is by far the most common method for securing components together and plays a significant role in determining the quality of a product. Atlas Copco offers industrial tools for tightening these fasteners, which are today suffering from errors in the applied torque. READ MORE

  3. 2. 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

  4. 3. Extended and Unscented Kalman Filtering for Estimating Friction and Clamping Force in Threaded Fasteners

    University essay from Uppsala universitet/Signaler och system

    Author : Mohammad Al-Barghouthi; [2021]
    Keywords : Estimation Theory; Extended Kalman Filter; EKF; Unscented Kalman Filter; UKF; Observability; Friction; Clamping Force; Tightening; Torque Controlled; Bolt; Threaded Fasteners;

    Abstract : Threaded fasteners tend to break and loosen when exposed to cyclic loads or potent temperature variations. Additionally, if the joint is held tightly to the structure, distortion will occur under thermal expansion issues. READ MORE

  5. 4. 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

  6. 5. Modular friction test rig for measuring torque and tension in threaded fasteners

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Reza Afsharian; Antonios Theodoropoulos; [2018]
    Keywords : friction test rig; tightening; shank torque; under-head torque; clamp force; friktionstest; åtdragning; axelmoment; undermoment; spännkraft;

    Abstract : This report describes the development of a modular friction test rig for threaded fasteners. This device can measure the shank torque and the clamp force during the tightening of threaded bolts, with a size of M3-M14 and clamp length of 30-160mm. READ MORE
