3. 2. Wavelet Galerkin methods for elastic multibody systems with unilateral contact constraints

   Författare :José Díaz López; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Elastic MBS; Contact; Unilateral Contraints; Wavelet; DAE; Daubechies; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

   Sammanfattning : In this thesis we investigate the applicability of wavelets to simulate the time behavior of elastic multibody systems (MBS) with contact constraints. For this end, a wavelet element method (WEM) was implemented, exploiting the special structure of the coupled ODE/PDE equations that govern elastic MBS. LÄS MER

4. 3. Cam Roller Contact

   Författare :Frederic Cabanettes; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; classification of surfaces; wear test; roller; rough contact model; surface topography; injection cam; manufacturing evaluation;

   Sammanfattning : The automotive industry and the design of engines are strongly ruled by performance andlegislation demands. First order aspects defining the main functions of a component are wellknown and new challenges appear at a lower scale. LÄS MER

5. 4. Cam Roller Contact : The topographical aspect

   Författare :Frédéric Cabanettes; Bengt Göran Rosén; Peter Hansbo; Högskolan i Halmstad; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 5. Modelling of Dynamic Contact - Exemplified on the Tyre/Road Interaction

   Författare :Krister Larsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tyre dynamics; rolling noise; rolling contact; dynamic contact; tyre road noise; tyre road interaction;

   Sammanfattning : Noise is a severe problem in modern society. Road traffic noise is a substantial contributor and the tyre/road interaction is the main noise source for normal driving conditions. Despite more than 30 years of research, there is a lack of quantitative tyre/road noise prediction models. LÄS MER
