  1. 1. Design and evaluation of a shock load resistant dynamic chain plate

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

    Author : Daniel Olsson; [2022]
    Keywords : Dynamic; chain; shock load; Simulink; FEA; conveyor; wear; experimental; Nordic Quick Systems; chain plate; Simulation; FEM;

    Abstract : Conveyor chains are often subject to repetitive shock loads during normal operations. This can cause accelerated wear in the chain leading to premature chain replacementor chain failure (Otoshi, 1997, p. 4). In this thesis a new approach for reducingshock load related wear in conveyor chains is proposed. READ MORE

  3. 2. Fatigue and microstructural study of a 316L austenitic stainless steel marine component produced by Wire Arc Additive Manufacturing (WAAM)

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Oskar Bremler; [2022]
    Keywords : Fatigue; steel; 316L; waam; wire arc additive manufacturing; AM; additive manufacturing;

    Abstract : In this study, the fatigue- and fracture properties and microstructure of a marine component of austenitic stainless steel 316L manufactured with the novel method Wire Arc Additive Manufacturing were investigated and compared with data from literature. The purpose was to find a critical flaw size in the material related to its fatigue life. READ MORE

  4. 3. Sandwich Design of a Platform Lift Floor

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Ruizhi Zhao; [2022]
    Keywords : Aluminium honeycomb sandwich; Fatigue analysis; Sandwich design; Sandwich joint design; SolidWorks simulation; Bikakesanalys; Bikakemönster sandwich; Sandwich design; SolidWorks-simulering; Utmattningsanalys;

    Abstract : Mobility is a symbol of dignity. A platform lift enables everyone of different physical abilities to move vertically with ease. Currently, the platform lift by Aritco Lift is made of steel sheet metal. It is heavy, thus difficult to handle. READ MORE

  5. 4. Comparison of Fatigue Life Evaluation Methods

    University essay from KTH/Hållfasthetslära

    Author : Louise Hedberg Lundblad; Anna Lund; [2021]
    Keywords : Solid Mechanics; Fatigue; Time history methods; Spectral methods; Truck components; Road induced vibrations; Hållfasthetslära; Utmattning; Tidshistoriksmetoder; Spektrala metoder; Lastbilskomponenter; väginducerade vibrationer;

    Abstract : The aim of this thesis is to investigate a selected set of fatigue life calculation methods and evaluate if they are suitable for fatigue life estimation of truck components at Scania. Failure due to fatigue can be cause by road induced vibrations, which is an inevitable phenomenon trucks are exposed to. READ MORE

  6. 5. Concept Design Improvement of Shift Fork for New Dog Clutch Actuator : Simulation driven product development approach

    University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design
