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

   Författare :José Díaz López; Matematik LTH; []

   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

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

   Nyckelord :contact; wear; wear prediction; wear model; wheel profile; rail profile; simulation vehicle-track interaction; multibody simulation; MBS; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : 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. LÄS MER
