  1. 1. Cam Roller Contact : Surfaces and Tribology

    Författare :Frédéric Cabanettes; Bengt-Göran Rosén; Ulf Olofsson; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wear reduction; camshaft; roller; surface topography; relocation; elasto plastic rough contact; elasto hydrodynamic lubrication; Mechanical engineering; Maskinteknik;

    Sammanfattning : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. In the valve train, mechanical components such as camshafts and rollers are defined by specifications including more and more constraints concerning their ability to face wear thus prolonging lifetime.

  3. 2. Synchronous Belt Mechanics and Durability - An Investigation Towards Life Prediction

    Författare :Tomas Johannesson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load distribution model; synchronous; camshaft drives; mathematical modelling; timing; belt; dynamic; wear; simulation; automotive; belt life prediction;

    Sammanfattning : An automotive synchronous belt transmits power and assures accurate timing between the crankshaft and camshafts. The automotive industry is very competitive: there is constant pressure to increase performance and lower costs. LÄS MER

  5. 4. A multi-objective evolutionary approach to simulation-based optimisation of real-world problems

    Författare :Anna Syberfeldt; Philip Moore; Robert I. John; Amos Ng; Högskolan i Skövde; []
    Nyckelord :Evolutionary algorithms; simulation-based optimisation; multi-objective optimisation; noise; TECHNOLOGY; TEKNIKVETENSKAP; Teknik; Technology;

    Sammanfattning : This thesis presents a novel evolutionary optimisation algorithm that can improve the quality of solutions in simulation-based optimisation.Simulation-based optimisation is the process of finding optimal parameter settings without explicitly examining each possible configuration of settings.

  7. 5. Turbocharged HCCI Engine, Improving Efficiency and Operating Range

    Författare :Thomas Johansson; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCCI; NVO; turbo; direct injection; combustion; CAI; low temperature; simulation; engine;

    Sammanfattning : Increasing fuel prices and environmental concern drives the research and development for the internal combustion engine. Homogeneous Charge Compression Ignition (HCCI) is a promising combustion concept with high fuel efficiency and low emissions. LÄS MER
