  1. 1. Improving comfort simulations of sleeping mattresses for IKEA

    Master-uppsats, Lunds universitet/Innovation

    Författare :Joel Elinder; [2020]
    Nyckelord :LS-Dyna; explicit finite element simulations; compressive testing; human soft tissue material models; mass scaling; hyperelastic material model validation; material validation; explicit timestep; Technology and Engineering;

    Sammanfattning : It is beneficial for a furniture company like IKEA to objectively and accurately evaluate what makes a mattress comfortable. But what defines comfort? IKEA currently investigates mattress comfort through extensive real-life user testing. Through which, six parameters of comfort have been identified. LÄS MER

  3. 2. Developing a Virtual Consumer: From Human Skin to FE Modelling

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Nyckelord :FEM; Skin; Dermis; Motion Capture; Technology and Engineering;

    Sammanfattning : In the 'on-the-go' society of today, the use of single unit beverage packages has increased. Consequently, the interaction between the consumer and the package have also attracted greater interest when trying to gain advantages in a competitive market. LÄS MER

  4. 3. Extraction of Material Parameters for Static and Dynamic Modeling of Carbon Black Filled Natural Rubbers

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Materialvetenskap

    Författare :Viktor Sandell; [2017]
    Nyckelord :Rubber; Modelling; Dynamic; Powertrain; Volvo Cars;

    Sammanfattning : Volvo Car Corporation (Volvo Cars) develops powertrain mounting systems that uses components made up largely of filled rubber materials. The development of such components is today relying on external suppliers to design components based on requirements set by Volvo. LÄS MER

  5. 4. Finite Element Modeling of Rubber Bushing for Crash Simulation - Experimental Tests and Validation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik

    Författare :Oscar Jesus Centeno Gil; [2009]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Until recently, the general level of detail in full car crash models has not allowed a physical modeling of rubber bushings with solid elements. This is partly because of the difficulty in modeling the complex characteristic of rubber, but also due to limited understanding of the mechanical properties of rubber materials. LÄS MER
