    Abstract : When skeletal fractures are too extensive for fixation with plates and screws, autografts are the most used technique for treating this. Within the biomedical field the interest in biodegradable implants made from additive manufacturing have increased. Magnesium alloys has also gained interest because of its favorable mechanical properties.. READ MORE

  6. 25. 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
