  2. 1. Simulation of Wheel and Rail Profile Evolution : Wear Modelling and Validation

    Author : Roger Enblom; KTH; []
    Keywords : contact; wear; wear prediction; wear model; wheel profile; rail profile; simulation vehicle-track interaction; multibody simulation; MBS; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Numerical procedures for reliable wheel and rail wearprediction are rare. Recent development of simulationtechniques and computer power together with tribologicalknowledge do however suggest computer aided wear prediction. READ MORE

  4. 2. Machinability variations in Alloy 718 —With focus on machining of turbine components

    Author : Pajazit Avdovic; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polar diagram; flank wear; ceramic tool; variation in material; tool wear; tool life; machinability; Inconel; Alloy 718; Machining; notch wear;

    Abstract : In gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). READ MORE

  5. 3. On Simulation of Uniform Wear and Profile Evolution in the Wheel - Rail Contact

    Author : Roger Enblom; Mats Berg; Simon Iwnicki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; wear; wear prediction; wear model; wheel profile; rail; Vehicle engineering; Farkostteknik;

    Abstract : Numerical procedures for reliable wheel and rail wear prediction are rare. Recent development of simulation techniques and computer power together with tribological knowledge do however suggest computer aided wear prediction as possible. READ MORE

  6. 4. Simulation and Measurement of Wheel on Rail Fatigue and Wear

    Author : Babette Dirks; Mats Berg; Roger Enblom; Mark Burstow; KTH; []
    Keywords : multibody simulations; prediction; wear; RCF; wheel; rail; cracks; measurements; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The life of railway wheels and rails has been decreasing in recent years. This is mainly caused by more traffic and running at higher vehicle speed. READ MORE

  7. 5. Tribological aspects of aluminium extrusion dies

    Author : Thomas Björk; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Extrusion; Die; Wear; Tool; Friction; Simulation; Bearing; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Extrusion is a common method to manufacture long products of aluminium, such as beams, rods and tubes. The aim of this thesis was to improve the material in the die bearing surface, and thereby the service life of extrusion dies through wear studies of actual dies, and experimental simulations.
