Abstract

The introduction of new railway systems in urban areas to ease road traffic congestion has led to concerns about the noise from trains, particularly as tracks often pass close to residential dwellings. One specific issue relates to the noise from trains or trams on bridges. The bridge design and construction can increase noise levels above those when the track is at grade. This paper addresses this issue, and reports two case studies to quantify the contributions to the total noise level from the wheel/rail noise, and from the noise radiated by the bridge structure itself including both the deck and the parapets. The studies involved, in the first case, consideration of the design and construction of a concrete and steel bridge and a comparison of pre-construction predictions, supported by finite element analysis, with in-use noise measurements. The second case involved noise and vibration measurements on an existing bridge to quantify the noise from the different sources, to compare simple predictions with measured noise levels, and to evaluate the effectiveness of various noise control measures. The good agreement between the predicted and measured levels in both case studies has led to the conclusion that the techniques provides a cost-effective method for the prediction of noise levels with an acceptable degree of accuracy. The techniques can also be used to evaluate the benefits to be gained from alternative noise and vibration control measures, and thus to define the most cost-effective control measure prior to implementation.

Bandgap analysis of partial-interaction composite beams periodically attached vibration absorbers
2024, International Journal of Mechanical Sciences
Elastic metamaterials with local resonant components exhibit unique bandgap behavior that can be utilized to control the vibration and noise of mechanical structures. This study aims to introduce the bandgap characteristics into the vibroacoustic control of partial-interaction composite beams (PICBs) widely adopted in civil engineering, aviation, and marine fields. Vibration absorbers are arranged periodically on the beam to generate a bandgap in PICBs, thereby transforming a conventional PICB into a metamaterial beam. An analytical approach is proposed to establish the spectral element (SE) matrix of a metamaterial beam based on the Timoshenko–Ehrenfest beam theory. Specifically, the governing equations of motion for PICBs follow Hamilton's principle. This model considers the effects of shear slip between two-layer sub-beams, shear deformations, and rotary inertia. The SE matrix of PICBs is then constructed and applied to obtain the SE matrix of the metamaterial beam by assembling the SE matrix of the vibration absorbers. Subsequently, the wave finite element (WFE) method is employed to predict the dispersion curve of the infinite metamaterial beam and the dynamic response of the finite metamaterial beam. In a benchmark example, the complex band structure and transmission indicated by the proposed approach are validated compared to those calculated by evaluation formulas of the literature and the finite element method. Lastly, the bandgap behavior for the vibration absorber parameters, lattice constants, and shear connector stiffness is investigated based on the defined dimensionless parameters. These results are valuable for optimizing vibration and noise reduction in PICBs equipped with attached vibration absorbers.
Derivation of train track isolation requirement for a steel road bridge based on vibro-acoustic analyses
2006, Journal of Sound and Vibration

The noise of steel railway bridges has attracted quite some interest in the last decade. The large majority of existing methods, see e.g. in Refs. [4–6], are analytical approaches for simple cases, or have been developed and verified for typical truss railway bridges. In the present case, however, all load-carrying structures of the bridge act as large noise radiating surfaces as well.
The paper reports on a hybrid method, aimed at predicting the expected noise emission of the structure-borne component of a combined bridge/track system, currently under development. The method is based on detailed vibro-acoustic analyses of the bridge and consists of three major elements: experimental estimation of input dynamic forces generated by rolling of trams along the track; a detailed analysis of the steel box girder bridge structure based both on experiments and numerical calculations; and estimation of sound radiation from the bridge structure performed by means of boundary element methods and validated on the bridge by vibro-acoustic measurements. The proposed method was used for the hypothetical case that no vibration isolation is installed and it was established that at least 10–12 dB(A) noise reduction is required. As reported elsewhere, the calculation can be repeated for isolated tracks and the efficiency of various track design versions can be evaluated.
The use of dynamic dampers on the rail to reduce the noise of steel railway bridges
2006, Journal of Sound and Vibration
Even if all steel railway bridges are different, most of them produce more noise than ballasted track. If located in populated areas, steel bridges may generate annoyance for the population. Specific noise reduction solutions must be developed. A research programme has been started to deal with this problem. The vibroacoustic study of a reference steel bridge has been carried out over the whole frequency range from 5 to 5000 Hz using the finite element method (FEM) in the low-frequency range and statistical energy analysis (SEA) at higher frequencies. At higher frequencies, the rail appears to be the main acoustic source. This result is confirmed by an experimental characterization. The spatial decay rates of the rail vibration are very low, due to the rail fastening system. Then, noise reduction solutions dedicated to the rail are considered, especially dynamic dampers which have been specified. Two products have been selected and tested on the reference bridge. The experimental results are discussed.
Research on noise and vibration reduction at DB to improve the environmental friendliness of railway traffic
2006, Journal of Sound and Vibration
One of the most prominent keywords relating to the environmental friendliness of railway traffic is noise reduction. Thus, the research and development programme “Low Noise Railway” of Deutsche Bahn (DB) is under way to treat the noise of the vehicles and infrastructure. The noise reduction of the trains and the rail/wheel system are being tackled within several projects.
The direct noise experienced by railway-lineside residents due to train movements on the track can be reduced by minimising the sound radiation directly at the source. This is the first-choice solution, as it proves to be the most effective countermeasure regarding a cost–benefit relation.
The limit values for the noise emission as specified in the technical specification for interoperability are an essential criterion to be confirmed during the procurement process of railway vehicles. A recently developed acoustical quality management scheme establishes systematic noise management to complete the vehicle procurement process in the phases of concept, design, construction and manufacturing.
In freight traffic quiet railway wheels for block brake operation will play an important role in the future to meet the goal of a low-noise railway system. A first attempt to realise successfully the low-noise potential of such optimised wheels was performed, even if with mixed results.
To show ways of reducing the noise of the cooling ventilation in locomotives, DB is a partner in a development project led by Siemens. A notable 8 dB(A) noise reduction was measured.
Concerning bridge noise, a project was started based on an effective and cost-efficient combination of experiments and simulations in order to develop specifications for the construction of generic low-noise bridges.
Noise from Railway Bridge
1998, Applied Acoustics
Noise is assessed by the time-average sound level, L_AT(x,D). The process of noise generation on a bridge and on an embankment is characterized by two parameters, $λ$ and $μ$ , which can be estimated from simultaneous measurements, L_AT(x₁,D) and L_AT(x₂,D). We assume that turbulence destroys the coherent interference between the direct and reflected waves. Thus, within 100 m of the track, geometrical spreading governs noise propagation. In the present study, there is satisfactory agreement between theory and experimental results.
