Use of vibro-isolation and non-conventional materials for reducing noise of railway wagons

Original language description

The implementation of European directives in practice is also closely related to the reduction of noise emissions from cargo wagons with the aim of protecting the environment. Reduction of the dynamic load of railway wagons must be taken into account during their design using appropriate vibro-isolation and unconventional materials in the production of individual components so as to reduce the transmission of structural noise from its main source. The paper analyses the procedures and conditions to reduce the transmission of vibration to the undercarriage and its superstructure, which is a tank, using suitable vibro-isolation materials both in strength and with required transmission loss. For this purpose, the paper analyses the frequency distribution of the vibration generated by the main sources of the wagon and its attenuation on individual components. The modal analysis of the tank wagon was complemented by the gravitational impact of the wheel with the rail generating its dynamic load. The transmission of the vibration of components from the wheel through the main suspension and the placement of the tank through the skids and the ball joint into the tank body is investigated. The solution is also based on theoretical and numerical analysis and methodology of transmission of vibration energy and on measurement of vibration at the entry and exit measurement points of individual components of the chassis of the wagon as well as the sound generation by the tank body itself. FFT and modal analysis were used to obtain the vibration and sound parameters. The transmission loss of individual components containing vibro-isolation elements was measured and the results were compared with theory. Finally, this article aims at some effective measures that may have the effect of reducing the unwanted transmission of structural noise and thus reducing the emission and immission of noise having a negative impact on the environment and human health.
