  1. 6. Design of Electro-Hydraulic Energy Converters : With Focus on Integrated Designs and Valve Plate Rotation

    Författare :Thomas Heeger; Liselott Ericson; Andreas Johansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In mobile working machines, there is a trend towards replacing combustion engines by electric machines to reduce their carbon footprint. This provides several advantages and challenges for the hydraulic system. The low efficiency of conventional hydraulic systems is no longer acceptable due to the volume and cost of batteries.

  3. 7. Fluids, Gels and Crystals : Phase behavior of binary thermoresponsive microgel mixtures

    Författare :Jasper Immink; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colloidal phase behavior; microgel; binary mixture; colloidal gel; sequential gelation; patchy particle; binary crystal; crystal-to-crystal transition;

    Sammanfattning : Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction.

  4. 8. The Microstructure of Metal Oxide Additive Silicon Nitride Ceramics

    Författare :Maria Knutson Wedel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microstructure; SEM; HIP; TEM; ZrO2; Si3N4;

    Sammanfattning : This work is concerned with Si3N4 ceramics fabricated with different metal oxide additives, viz. Y2O3, Al2O3, ZrO2 and ZrO2(+3 mol% Y2O3), which have been densified by hot isostatic pressing (HIP). LÄS MER

  5. 9. Deformation Behaviour of Near Fully Pearlitic Railway Steels During Monotonic and Cyclic Loading

    Författare :Niklas Köppen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCF; low cycle fatigue; Near fully pearlitic steels; work hardening; microstructure; tensile deformation; medium carbon steel;

    Sammanfattning : The main conclusions that could be drawn from the present work are that the deformation behaviour of fully and near fully pearlitic steels is very similar and that a combination of low temperature, prestraining and high deformation rates is critical for the performance. This was shown from microscopy studies, tensile, impact and low cycle fatigue (LCF) testing. LÄS MER

  7. 10. HAM-Tools - An Integrated Simulation Tool for Heat, Air and Moisture Transfer Analyses in Building Physics

    Författare :Angela Sasic Kalagasidis; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HAM transfer; Whole building HAM model; Simulink modeling; International Building Physics Toolbox;

    Sammanfattning : HAM-Tools is a building simulation software. HAM stands for Heat, Air and Moisture transport processes in a building and building envelope that can be simulated by this program, and Tools describes its modular structure. The main objective of this tool is to obtain simulations of transfer processes related to building physics, i.e. LÄS MER
