2. 6. Cam Roller Contact : The topographical aspect

   Author : Frédéric Cabanettes; Bengt Göran Rosén; Peter Hansbo; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; injection cam; roller; surface topography; rough contact model; wear test; classification of surfaces; manufacturing evaluation; Mechanical manufacturing engineering; Mekanisk tillverkningsteknik;

   Abstract : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. First order aspects defining the main functions of a component are well known and new challenges appear at a lower scale. READ MORE

4. 7. Cam Roller Contact : Surfaces and Tribology

   Author : Frédéric Cabanettes; Bengt-Göran Rosén; Ulf Olofsson; Högskolan i Halmstad; []
   Keywords : 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;

   Abstract : 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.

5. 8. Tribological and Mechanical Behaviour of Lamellar and Compacted Graphite Irons in Engine Applications

   Author : Rohollah Ghasemi; Anders Professor; Lennart Assistance professor; Bengt-Göran Rosén; Anders Jarfors; Lennart Elmquist; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sliding wear; abrasive wear; graphite lubricating performance; matrix deformation; lamellar graphite iron; high-Si compacted graphite iron;

   Abstract : There has been much discussion about the beneficial uses of lamellar graphite iron in piston rings–cylinder liner systems, where a good combinations of both thermal and tribological properties are essential. The excellent tribological performance of lamellar iron under such sliding conditions is principally associated with lubrication behaviour of the graphite particles which are distributed as lamellas throughout the matrix.

6. 9. Towards Topography Characterization of Additive Manufacturing Surfaces

   Author : AMOGH VEDANTHA KRISHNA; Bengt Göran Rosén; Frederic Cabanettes; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser-based Powder bed fusion; Fused deposition modeling; Structured light projection; Stylus profilometer; Multiple regression; Areal surface texture parameters; Profile parameters; Feature-based characterization; Power spectral density; Scale-sensitive fractal analysis; Confocal fusion; Additive manufacturing;

   Abstract : Additive Manufacturing (AM) is on the verge of causing a downfall to conventional manufacturing with its huge potential in part manufacture. With an increase in demand for customized product, on-demand production and sustainable manufacturing, AM is gaining a great deal of attention from different industries in recent years. READ MORE

7. 10. On Polishability of Tool Steels

   Author : Sabina Rebeggiani; Bengt-Göran Rosén; Liam Blunt; Högskolan i Halmstad; []
