چکیده
To effectively improve the estimated level of railway vehicles’ vertical dynamic responses and provide a more suitable reference for selection its secondary suspension damping parameter, this paper has derived root mean square values analytical formulae car body acceleration, stroke, axle box action force vehicles under random excitation track closer to actual characteristics. The correctness is verified by testing real vehicle. Then, according derived, an design method optimal ratio system constructed based on multi-objective programming single-objective interval constraint analysis, which can be used find best trade-off conflicting performance indices, such as ride comfort, running smoothness, safety, influences parameters are analysed. This research characterize vibration response effective initial vehicle parameter.

The dynamic response of the railway under accelerated moving load using Dynamic Green Function is presented in this paper. For this purpose, an exact and direct modeling technique is introduced for the railway modeling as the damped Euler-Bernoulli beam on the partial Winkler foundation with arbitrary boundary conditions subjected to the moving load. The effects of the elastic coefficient of Wi...
