  1. 1. Method Development & Analysis of Seals using FEM

    Master-uppsats, KTH/Maskinkonstruktion

    Författare :Lovisa Svanborg Östlin; [2023]
    Nyckelord :FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

    Sammanfattning : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. LÄS MER

  3. 2. Fracture simulation with a hyperelastic phase field model

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Adrien Fradet; [2023]
    Nyckelord :Fracture; Phase field modeling; Hyperelasticity; Brott; fasfält-methoden; hyperelasticite;

    Sammanfattning : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.

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

    Master-uppsats, KTH/Farkostteknik och Solidmekanik

    Författare :Mårten Vuorinen; [2022]
    Nyckelord :;

    Sammanfattning : 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.

  5. 4. FE Simulation of protective insulation of catalysts in exhaust after-treatment systems of trucks and buses : Investigation and characterization of catalytic converter support mat material for accurate modeling in finite element simulations

    Master-uppsats,

    Författare :Manroop Bhattasali; [2022]
    Nyckelord :Catalytic converter; packaging mats; support mats; compression; friction; hyperelastic; hyperfoam; viscoelastic; canning; finite element;

    Sammanfattning : The increase of new and ever more stringent emission legislation has brought about with it a surge in the demand for more sustainable automotive solutions. This has particularly been the case for automobiles, including heavy-duty vehicles like trucks and buses, with internal combustion engines, which now require the design and manufacturing of more durable and reliable components.

  7. 5. Verification of elastomer characteristics in electro-mechanical linear actuator

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

    Författare :Rohit Karmungikar; [2022]
    Nyckelord :ANSYS; Aging; Hyperelastic; MATLAB and Mooney-Rivlin; ANSYS; Åldrande; Hyperelastic; MATLAB och Mooney-Rivlin;

    Sammanfattning : Cascade Drives develops electromechanical actuators using a rack and pinion configuration to achieve a combination of high load and high-speed operation. A patented load distribution mechanism enables the use of multiple pinions on a single rack, resulting in a compact unit with high positional accuracy capable of absorbing shock loads. LÄS MER
