EN 15610: Railway applications – Acoustics – Rail and wheel roughness measurement related to noise generation standard

EN 15610: Railway applications – Acoustics – Rail and wheel roughness measurement related to noise generation standard is a crucial guideline for professionals in the railway industry who are concerned with noise reduction and mitigation. This standard provides specific criteria and methods for measuring and evaluating the roughness of rails and wheels, which directly impacts noise generation.

1. Significance of EN 15610:

The primary objective of EN 15610 is to establish standardized procedures that enable accurate and consistent assessment of rail and wheel roughness. By doing so, it helps engineers and technical personnel identify and address sources of excessive noise caused by rail and wheel roughness. Compliance with this standard aids in optimizing noise reduction efforts and enhancing overall passenger comfort and environmental well-being.

2. Acoustics and Noise Generation:

Railway noise has become a growing concern due to its impact on nearby communities and the environment. Noise generated from rolling stock, including trains and trams, is strongly influenced by the roughness of the rail and wheel surfaces. Higher roughness levels lead to increased vibration and noise emission during train operations. Hence, precise measurement of rail and wheel roughness is essential for effective noise control measures.

3. Measurement Techniques:

EN 15610 outlines various techniques for quantifying rail and wheel roughness. These include contact-based methods, such as profilometry and wavelet analysis, as well as non-contact methods like laser-based systems. These techniques allow professionals to obtain accurate roughness measurements, providing valuable data for noise prediction models and further analysis.

4. Evaluation Parameters:

The standard defines specific parameters for assessing rail and wheel roughness, such as mean roughness depth (Rz), peak-to-valley height (Rt), and spatial wavelength cutoff (λc). These parameters help quantify the amplitude, frequency, and spatial characteristics of roughness, enabling comparative analysis and benchmarking. By adhering to these evaluation parameters, professionals can make informed decisions regarding noise-reduction interventions.

5. Practical Applications:

EN 15610 finds broad applications in the railway industry. It aids in the design and manufacturing of quieter rail systems, including tracks, wheels, and other components that contribute to noise reduction. The standard is also utilized during maintenance and inspection activities, allowing engineers to identify areas where rail and wheel roughness may require attention or intervention.

In summary, EN 15610: Railway applications – Acoustics – Rail and wheel roughness measurement related to noise generation standard is an essential tool for professionals seeking to minimize noise emissions in the railway industry. By following the guidelines outlined in this standard, engineers and technical personnel can accurately measure and evaluate rail and wheel roughness, leading to informed decision-making and effective noise control strategies.
