Rolling Noise Simulation: A New Approach in Time Domainndary conditions, using an impedance technique, have been developed for the case of a finite Euler-—Bernoulli beam model representing the rail. The full problem has been solved using a finite difference scheme. The performance of the absorbing boundary conditions has been studied by comparing the re

Bridging the Gap from Multibody Simulations to Acoustic Analysisreuse of model-components and scenarios originating from comfort evaluations are advantages that motivate the extension of the multibody methodology towards acoustic analysis..Therefore, this paper presents model enhancements of the contact behavior of wheel and rail that are intended to be used in

Dynamic Models of Railway Track Taking Account of Cross-Section Deformation at High Frequencyin the rail are studied by means of Hamilton’s principle. Comparing the results in terms of the dispersion relations, the tapered plate rail model shows good agreement with an FE model. Comparison with simpler beam models confirms the improvements at high frequencies due to the taper of the foot.
