  1. 1. Evaluation of a Test Rig to Determine the Need For Human Operators in Ergonomic Testing of Pistol Grip Power Tools

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

    Författare :Felix Ekman; Axel Sernelin; [2023]
    Nyckelord :;

    Sammanfattning : Handheld power tools are found in many different manufacturing processes, everywhere from miniature screw joints in cell phones to safety-critical joints in automotive vehicles. The tools are often used for many consecutive hours which emphasizes the need for good ergonomics to ensure the safety of the operators. LÄS MER

  3. 2. Modeling of a ball contact with a coated plate

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Vindstabilisering av SIPS byggnader i Sverige

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Hasani Esmael; Maniea Johan; [2023]
    Nyckelord :SIPS; wind; joint; finite element method; Stabilisering; Förband; Konstruktion; SIPS; FEM; Vind;

    Sammanfattning : This work is about wind stabilization of a SIPS building in Sweden where the focus is onhow joints take place between the foundation plate and the walls. SIPS (Structural insulatedpanels) is a load-bearing insulation element used to build the entire building envelope. LÄS MER

  5. 4. Evaluation of pretension losses in heated screw joint

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Joel Svensson; [2022]
    Nyckelord :screw joint; clamping force; thermal load;

    Sammanfattning : The heated flow within the silencers of heavy transport vehicles can easily reach temperatures of hundreds of degrees Celsius. The thermal loads can cause problems for certain components on a silencer. LÄS MER

  7. 5. Axially loaded screw joints in wooden structures exposed to fire : Fire tests in furnace and numerical calculations in TASEF of different screw mounting variations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Henrik Pettersson; Emma Wiklund; [2022]
    Nyckelord :Fire; wood; screw joints; strength; temperature; TASEF; Brand; trä; skruvförband; bärförmåga; temperatur; TASEF;

    Sammanfattning : To achieve sufficient stability of a structure in a fire scenario, a thorough design of joints in wooden structures are as important as the design of the construction itself. As an earlier study points out, there are no existing design method available to determine the load capacity of an axially loaded screw joint in wooden structures, which complicate the process of a thorough design of the joint in a fire scenario.
