Noise & Vibrations


Noise & Vibrations In-Depth Focus 2018

4 December 2018 | By

As a result of climate change and strong political agendas, a shift from road to rail traffic is expected. But this could lead to increased rail noise and vibration if action is not taken to research, understand and implement new tools that will improve the acoustic performance of train design.…

Measuring the vibration-isolating effect of an elastic railway superstructure in Poland

13 February 2018 | By , ,

The Railway Institute at Wrocław University of Science and Technology has convincingly demonstrated the value of the cost-effective type SLS1308G under sleeper pads used on the Kraków Airport rail link in Poland. Here, Ewelina Kwiatkowska, Adjunct Professor at Wrocław University of Technology, together with Getzner Werkstoff colleagues Harald Loy (Head…

Influence of rail and wheel roughness on rolling noise: Measurements and analysis

16 November 2017 | By

Roughness of the rail and wheel running surfaces produce rolling noise – the most significant form of noise due to wheel-rail contact. Rolling noise from conventional metro trains, tramways, streetcars, electrical or diesel multiple units and even high-speed trains is a key consideration during the design, homologation and testing phases;…

Noise & Vibrations supplement 2016

23 November 2016 | By

In this Noise & Vibrations supplement Marcin Wójcik discusses why rail noise needs to be addressed, Maria Price and Markus Vaerst assess retrofitting rail freight wagons, and Adrian Egger and Markus Heim cover quality control measurements after 30 years of operation...

Quality control measurement of a MSS after 30 years of operation

6 November 2016 | By ,

An investigation into the effectiveness of one of the first mass-spring systems (MSS) in Switzerland is currently ongoing. After 30 years of operation, the vibration-reducing lightweight MSS is still performing without faults, despite the elastic bearing of the slab now being partially submerged in water. Vibration engineering experts Adrian Egger…

Why rail noise needs to be addressed

5 November 2016 | By

Noise is one of the most widespread causes of public health problems in the European Union and also results in significant economic costs, including health-related productivity losses. According to the World Health Organization (WHO)1 noise is, after air pollution, the second biggest source of diseases and premature deaths. The European…
