  1. 1. Optimal dead space in axial-type expander

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Martin Karman; [2022]
    Nyckelord :Dead space; Expander; Steam engine; Tolerance analysis; Axial-kolvmotor; Effektivitet; Expansionskammare; Kolv; Ångmotor;

    Sammanfattning : In this thesis a method for determining optimal dead space in an axial-type expander is developed. The axial-type expander in question is for use in a steam engine, a environmental friendly and fuel-agnostic alternative to the ICE-engine. LÄS MER

  3. 2. Evaluation of Different Concepts for Pressed and Sintered Connecting Rods

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Mattias Rehn; [2019]
    Nyckelord :Connecting Rod; Con Rod; Fatigue; Buckling; Manufacturing; Höganäs AB; CAD; FEM; FEA;

    Sammanfattning : Connecting rod are found in most combustion engines and transmits thrust from the piston to the crankshaft. The connecting rod needs to withstand forces from the piston and inertia forces which results in axial tension, compression stresses and bending. LÄS MER

  4. 3. Hydraulic pump efficiency test evaluation and improvement : Calculation, presentation and automation

    Kandidat-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Simon Stolpe; Nils Slycke; [2018]
    Nyckelord :Pump efficiency calculation hydraulic test;

    Sammanfattning : During this project the method and calculation for a hydraulic axial piston pump efficiency test has been evaluated. There are difficulties in how the maximum displacement of an axial piston pump is defined and this also affects the efficiency calculation of the test. LÄS MER

  5. 4. Simulation of Tribological Contacts in Hydraulic Machines

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Fredrik Roselin; [2018]
    Nyckelord :Tribology; Friction; Wear; Lubrication; Mixed lubrication; Luleå Mixed Lubrication Model; LMLM; Tribologi; Friktion; Nötning; Smörjning; Blandad tunnfilmssmörjning;

    Sammanfattning : Axial piston machines are operating at high pressure and varying speeds, which requires high reliability of the components. The machine components are separated by a fluid film, but sometimes this film gets penetrated by the surface asperities causing the machine to operate with metal-to-metal contact. LÄS MER

  7. 5. The Effects of Different Earth Pressure Coefficient at Rest in Triaxial Shear Tests on Clay

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Jo Forseth Indgaard; [2017]
    Nyckelord :Clay; Triaxial Shear Tests; Earth Pressure Coefficient;

    Sammanfattning : Triaxial shear test is the most accurate test for deciding the undrained shear strength of clay. In every test the ratio between the horizontal and vertical stresses, the coefficient of earth pressure at rest (K0′), has to be decided. LÄS MER
