TL;DR: In this paper, the authors define and compare alternative mathematical modelling approaches for the secondary air-spring suspension and assess their effect on the accuracy of rail vehicle dynamics multibody simulation, and demonstrate that a dynamic model of the airspring is required to assess ride comfort correctly, especially when the pneumatic layout of the suspension includes a long pipe between the air spring and the reservoir.

TL;DR: In this paper, the authors gratefully acknowledge the support for this work provided by the Project TRA2010-15669 (Ministerio de Ciencia e Innovacion) and TRA2007-67167 (Ministario de Educación y Ciencias-FEDER).

TL;DR: In this article, a process to define an accurate component model is proposed based on a combination of laboratory tests and model identification techniques, and six models for the air spring secondary suspension are discussed and assessed based on comparison with experiments.

TL;DR: The paper reviews the criteria for nonlinear assessment of vehicle stability based on the simulation of vehicle response to random track irregularity, showing the need for more objective criteria than the ones based on physical testing for vehicle homologation.

TL;DR: In this paper, the DynoTRAIN project has presented a unique amount of testing, simulations, comparisons with measurements, and validation evaluations, including several different vehicles on a test train equipped to simultaneously record track irregularities and rail profiles.
