  3. 2. Methodology for analysis of vibration isolating systems

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Jonas Olsson; [2023]
    Keywords : Vibration;

    Abstract : Vibration causes problems in many kinds of machinery including fighter aircraft. It can, for example, cause structural fatigue, malfunction in equipment and injuries to humans. The sources of vibration are engines, flow disturbance and separation of external loads, to mention some. READ MORE

  4. 3. Development of a Method to Determine the Influence of Rubber Components in Dynamic Simulations

    University essay from KTH/Farkostteknik och Solidmekanik

    Author : Mårten Vuorinen; [2022]
    Keywords : ;

    Abstract : In order to make sure that an engine can withstand the vibration loads, while the weight is kept as low as possible, some components on the engine are made of rubber. The stiffness of these rubber components are several orders of magnitude lower than the surrounding metal components, and the inclusion of rubber components affects the dynamic behaviour of the engine.

  6. 5. 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
