  1. 21. Property Optimization of PM-gearing

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Marcus Söderberg Jansson; Oskar Lundkvist; [2017]
    Keywords : Gear; Powder Metallurgy; Property optimization; Egenskapsoptimering; Kugghjul; Pulvermetallurgi;

    Abstract : The purpose of this bachelor thesis is to design and optimize a powder metal gear through FEM-analyzes. The moment of inertia and weight of the gear shall be reduced at the same time as the demands on tension and bending stiffness are met. READ MORE

  3. 22. The influence of grain size on mechanical properties of Inconel 718

    University essay from Linköpings universitet/Konstruktionsmaterial

    Author : Muhammad Moiz; [2013]
    Keywords : Super alloys; Inconel 718; microscopy; grain size;

    Abstract : The thesis work discuss about how the materials mechanical properties are influenced by the microstructure. The most common way of altering the microstructure of the material is by heat treatment.The mechanical properties that are of interest are strength, toughness, ductility, creep and fatigue.

  4. 23. Investigation and Simulation of the Heating Effects in Sandwich Cores During Vibrational Loading

    University essay from KTH/Lättkonstruktioner

    Author : Jacob Langer; [2013]
    Keywords : ;

    Abstract : GKN Aerospace Engine Systems specializes in large load carrying static structuresfor aero engines and is, as part of a light weight strategy, developing design andmanufacturing technology to be able to complement the current metallic product offerwith composite fan guide vane structures. Fan vanes in modern engines are structuraland to meet the requirements for low weight in the aircraft industry, it is necessary todesign the vane as a sandwich structure. READ MORE

  5. 24. Mechanical Engineering for Electronics.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Loïc Was; [2012]
    Keywords : ;

    Abstract : Schlumberger drilling tools are exposed to very hard loading conditions (shocks, vibrations, thermal cycling) while performing a job. As these tools are full of electronics, issues can quickly come from electronics failure. Mechanisms of failure occurring in electronics are very complex but can be predicted in some cases.

  6. 25. Weld Analysis in Combustion Chambers Subjected to Thermo-Mechanical Fatigue Load Conditions

    University essay from Hållfasthetslära

    Author : Johnny Johansson; [2011]
    Keywords : Weld; analysis; TMF; fatigue;

    Abstract : At cyclic operation of gas turbines, components are subjected to thermo-mechanical fatigue (TMF) due to the high temperature gradients that arises. In this thesis life assessment of welds in combustion chambers are at focus. READ MORE
