SIMULATION: CATdBTren
CATdBTren is a research and development project with the objective of giving an answer to the new necessities of the sector with regard the field of vibrations. This way, the creation of a consortium formed by highly renowned companies within the sector and which carried the same name is promoted.
During the last decades, technological progress and development have been two of the main characteristics of the railway industry. This has made it possible to achieve railway infrastructures with high levels of performances, offering passengers an efficient mobility with high levels of comfort and speed which were, until recently, unthinkable.
Despite the fact that these technological improvements place the railway transport in a clearly advantageous position compared to other means of transportation, they also affect a number of previously detected problems such as the effect of these railway infrastructures on the environment, in particular regarding noise and vibrations.
Nowadays, the noise and vibration levels generated by railway traffic not only are a source of neighbour complaints at particular areas in exceptional situations but they have become a general public matter. All companies in the sector, operators and administrations devote important resources in order to monitor, predict, understand and reduce these vibration levels from our homes, schools, hospitals and other critical buildings. To reduce them from both the already existing railway lines, and also from new projects under development where it is important to act before the problem appears.
With regard the noise propagation problems, at present we count with many prediction tools that make it possible to evaluate the impact of this phenomenon at the initial stages of the construction project.
On the other hand, this is not the case for the vibration propagation phenomenon. In this field there are no prediction tools available which make it possible to evaluate this phenomenon at early stages of the construction of the railway infrastructures.
Thus, the necessity to deal with this issue emerges as the only urgent technical challenge to be solved by the companies related with the sector.
