  1. 1. 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.

  3. 2. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

    University essay from KTH/Hållfasthetslära

    Author : Abhiroop Chatterjee; [2023]
    Keywords : ;

    Abstract : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. READ MORE

  4. 3. Model parameter estimation for a handheld nutrunner

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Jonathan Fridstrand; Johanna Sturk; [2020]
    Keywords : ;

    Abstract : The purpose of this project is to investigate the angled nutrunner, which is a hand held torque tool often used in the industry to tighten bolted joints. The goal is to estimate parameter values for an existing model that can describe the reaction force and the angular displacement of the tool as a function of the torque transferred to the joint.

  5. 4. Influence of liquid shim on the bearing strength of a composite bolted joint

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Eric Johan Klas Voortman Landström; [2019]
    Keywords : ;

    Abstract : The objective of this thesis has been to investigate the effect a liquid shim has on the bearing strength of a composite bolted joint. The shim is necessary to close gaps that occur during the assembly of the joints, preventing the structural parts from being fastened correctly. READ MORE

  6. 5. Development of a test rig for handheld nutrunners

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Jonas Ferlin; Viktor Johansson; [2017]
    Keywords : Nutrunner; Test rig; Torque; Alignment; Sensor; Mutterdragare; Testrigg; Moment; Linjering; Givare;

    Abstract : As the demands for precision in nutrunners increases, the testing equipment at manufacturers of these tools also need to get better. At Atlas Copco in Tierp there are a number of test rigs that compare the torque that the nutrunners indicate, with the torque that a sensor records. READ MORE
