  1. 1. Modeling of a ball contact with a coated plate

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mohammadreza Saeedi; [2023]
    Keywords : Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

    Abstract : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. READ MORE

    Abstract : Lesjöfors Fjädrar AB is a spring manufacturing company. At the start of each manufacturing process when manufacturing cold coiled compression springs, the operators manually feed the spring wire from a reel that contains the raw spring wire, into the machine where the springs are made. This is a demanding process for the operators. READ MORE

  5. 4. Design of a variable focal length optics for a SWIR Earth observation camera

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Sergio David Díaz Martínez; [2021]
    Keywords : ;

    Abstract : This thesis consists of a preliminary design study of a variable focal length optics for a SWIREarth observation camera which is planned to be placed inside a 6U Cubesat. After thesuccess of DRAGO instrument consisting on a SWIR camera onboard a Cubesat, which hasbeen recently launched (January 2021), the Institute of Astrophysics of the Canary Islands(IAC) began this project with the intention of adding zoom optics to SWIR space imagingsystems.
