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

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

    Author : Felix Ekman; Axel Sernelin; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Catenary action to prevent progressive collapse in multistorey timber buildings : An experimental study of tube joints

    University essay from Luleå tekniska universitet/Träteknik; Luleå tekniska universitet/Institutionen för tillämpad fysik, maskin- och materialteknik

    Author : Sivert Knutsen; [2023]
    Keywords : wood; engineering; construction; massive timber; tube joints; Progressive collapse;

    Abstract : In the modern building industry wood as a building material has been looked on as one of the solutions to lower the environmentally impact of the building industry. Building types that normally have been reserved for concrete and steel are today being built with wood as main load bearing component. READ MORE

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

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Joel Svensson; [2022]
    Keywords : screw joint; clamping force; thermal load;

    Abstract : 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. READ MORE

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

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

    Abstract : 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.

  6. 5. Classification of ultrasonic signals using machine learning to identify optimal frequency for elongation control : Threaded fastening tools

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Mazen Bahy; [2022]
    Keywords : Machine Learning; Convolutions Neural Network CNN ; Barker signals; Ultrasonic sensors; Clamp-force; Threaded fastening assembly; Maskininlärning; konvolutionellt neuralt nätverk; Barker-signaler; Ultraljudssensorer; klämkraft; Åtdragningsmontering;

    Abstract : Studying the preload in a screw joint has been the focus of today’s industry. The manufacturer reflects that demand by investigating different opportunities and techniques to develop this area. There are four different ways of controlling the tightening of bolts and joints to achieve the required clamp force that can hold for a specific preload. READ MORE
