2. 1. Advancing Front Mesh Generation Techniques with Application to the Finite Element Method

   Author : Jan Frykestig; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advancing front method; mesh size distribution; automatic mesh generation; finite element method; surface mesh generation; spatial data structures;

   Abstract : The present study deals with automatic mesh generation with application to finite element methods. We focus our interest on unstructured mesh generation, and in particular on advancing front methods for which algorithms for meshing of two and three dimensional domains as well as of free-form surfaces are devised.

4. 2. Churning losses and efficiency in gearboxes

   Author : Martin Andersson; Ulf Olofsson; Stefan Björklund; Ulf Sellgren; Bo Alfredsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gears; efficiency; temperature; running-in; assembly; torque loss; surface roughness;

   Abstract : Efficient transmissions systems are key to producing competitive motor vehicles that have a smaller environmental impact. Gears are the main components in vehicle transmissions and although they are already highly efficient, there is still room for improvement. READ MORE

5. 3. Modelling and simulation of mechanical cutting

   Author : Vahid Kalhori; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

   Abstract : The commercial success of a new product is influenced by the time to market. Shorter product lead-times are of importance in a competitive market.This can be achieved only if the product development process can be realised in a relatively small time period. READ MORE

6. 4. The influence of modelling parameters on the simulation of car tyre rolling losses and rolling noise

   Author : Carsten Hoever; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling resistance; modelling parameters; parameter study; radiation; tyre road noise; tyres; tyre road interaction; waveguide finite element;

   Abstract : Due to legislative changes within the EU there is an increased demand for improvement in car tyre rolling resistance and noise generation. Yet, apart from empirical data based on measurements, there is little information concerning the relationship between rolling resistance and rolling noise generation. READ MORE

7. 5. Numerical simulation of thermomechanically coupled transient rolling contact - An arbitrary Lagrangian-Eulerian approach

   Author : Andreas Draganis; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermomechanical coupling; finite element method; transient analysis; arbitrary Lagrangian--Eulerian; rolling contact; frictional contact;

   Abstract : Numerical simulation of rolling contact serves as an important complement to laboratory and full-scale testing in the endeavour to further the understanding of related physical mechanisms, e.g. the influence of friction on the rolling motion, the thermomechanical interaction, damage phenomena and related modes of failure.
