摘要

This paper deals with the development of a numerical model describing the vibroacoustic behaviour of high-speed train coaches in the low-frequency range. This model which has been developed at the SNCF aims to improve the acoustic comfort of the passengers. This project has provided an overall view of the main physical phenomena occurring within a coach. Therefore the model has been developed using a simplified theoretical approach. Initial hypotheses and the main features of the model are then described. The different stages of the validation tests are discussed and a typical example of the usefulness of this tool is provided. Finally, further developments of the software are presented.
