  1. 1. Development of Elastic Mechanism for actuation of Valve

    University essay from KTH/Maskinkonstruktion

    Author : Nidhi Menon; [2023]
    Keywords : Compliant mechanism; Engine; HGR valve; Heat gas recirculation; Eftergivlig mekanism; HGR-ventil; läckage; varmgasåtercirkulationsventilen;

    Abstract : The HGR valve, or hot gas recirculation valve, is an essential component of modern internal combustion engines. Its main function is to reduce emissions of nitrous oxide (NOx), which is a harmful pollutant produced during combustion. READ MORE

  3. 2. New design and construction of hightemperature tribology testingequipment : in the context of hard coatings

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Atle Andersson Nykvist; [2023]
    Keywords : Tribology; friction; wear; hot wear; hot wear tester; design; construction; tribometer; tribo tester; tribo-tester; Tribologi; friktion; nötning; varmnötning; varmnötare; design; konstruktion; tribometer; tribotest;

    Abstract : There are two main goals of this thesis. Firstly, to improve and develop an existing hot weartester at Karlstad University so that it may test more samples of different sizes. Secondly, totest previously impossible samples and investigate their tribological properties and measurethe coefficient of friction with high reproducibility. READ MORE

  4. 3. Optimization of hot strip drawing test methodology for hot forming of aluminium alloys

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

    Author : Rabia Arshad; [2022]
    Keywords : Hot forming of aluminium; friction; high temperature lubrication; strip draw; wear.;

    Abstract : The development of lightweight design for automotive applications has lasted for many years and is still increasing. Vehicles with light structures use less fuel, emit less CO2, and are better for the environment. READ MORE

  5. 4. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : William Tönnberg; [2022]
    Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

  6. 5. Process development and optimization towards binder jetting of Vanadis 4 Extra

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Jivesh Jain; [2022]
    Keywords : Binder jetting; tool steel; Vanadis 4 Extra; sintering; debinding; wear resistance;

    Abstract : Additive manufacturing (AM) has experienced significant growth and development in recent years, owing to the ability to produce complex parts using a wide range of materials with relative ease. Powder bed-based metal AM has been at the forefront of this growth, even reaching the point where parts can be manufactured for end-use applications. READ MORE
