  1. 6. Designregler för momentarm

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Max Wallerman; [2023]
    Nyckelord :Maskinteknik; FEM;

    Sammanfattning : Bosch Rexroth is a company that manufactures radial piston hydraulic engines and accessories, commonly used in industries such as mining and marine applications. These engines generate significant torques during operation, often requiring the use of torque arms to handle the torque. LÄS MER

  3. 7. Comparative analysis of contact and non-contact method for determining the natural frequencies of a bolted joint

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

    Författare :Malin Dyberg; Elvira Troillet; [2023]
    Nyckelord :;

    Sammanfattning : 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.
