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

    University essay from KTH/Maskinkonstruktion (Inst.)

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

    Abstract : 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. READ MORE

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

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Abstract : 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. READ MORE

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

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Simon Stolpe; Nils Slycke; [2018]
    Keywords : Pump efficiency calculation hydraulic test;

    Abstract : 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. READ MORE

  5. 4. Simulation of Tribological Contacts in Hydraulic Machines

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Jord- och bergmekanik

    Author : Jo Forseth Indgaard; [2017]
    Keywords : Clay; Triaxial Shear Tests; Earth Pressure Coefficient;

    Abstract : 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. READ MORE
