This paper presents an efficient method to predict underground railway-induced vibrations. The method uses the finite element method (FEM) to model the railway tunnel structure and the singular boundary method (SBM) to model the wave propagation in the surrounding soil. The FEM mesh and the distribution of SBM collocation points at the tunnel/soil interface are generated using an automatic meshing strategy. The presented method is one of the main components of VIBWAY, a user-friendly prediction tool to address railway-induced vibration problems. This paper presents three calculation examples in which the soil response due to forces applied on the tunnel structure are computed in terms of transfer functions. The results obtained for each one of the calculation examples are compared with those computed using a model based on a 2.5D FEM-BEM approach. The presented comparisons show that the proposed approach is a suitable strategy for predicting underground railway-induced vibrations, both in terms of accuracy and computational efficiency. Moreover, the use of an automatic meshing strategy and the SBM formulation not only eases the implementation of the approach but it also makes it easier to use, which is one of the key features of the VIBWAY tool.

Babici, Laura Mariana; Tudor, Andrei; Romeu Garbí, Jordi
The paper aimsto analyse the occurrence of acoustic emission at the wheel-rail contact during microslip. The experimental model allows the different loads and the low sliding speeds specific to the wheel-rail contact. It is determined experimentally the appearance of the stick-slip phenomenon at the Hertzian contact of cylinder type (fixed-wheel specimen) - plane (mobile with very low speed - rail specimen). The experimental stand simultaneously measures the normal force, the friction force and the acoustic emission at different normal forces, sliding speeds and rigidities of the wheel specimen fixing system. The specimens are made of UIC standard materials used in the driving wheels and rails. The stick-slip phenomenon occurs at low micro-slip speeds and normal bending stiffness. Experimentally, it is found that the jumps specific to the stick-slip phenomenon (friction coefficientCOF) are accompanied by the acoustic emission (AE) at the cylinder-plane interface. The energy emitted by AE (WAE) is correlated with the energy consumed by friction during the stick-slip period (WCOF).

This paper aims to introduce preliminary statement of methods of a computationally efficient and user-friendly toolbox, called VIBWAY, able to predict vibration and re-radiated noise levels in two situations. On the one hand, it can predict levels in existing buildings due to new lines or after the application of mitigation measures in existing operational railway infrastructures. Thus, it can be used to assess the performance of vibration countermeasures applied at the track, at the soil and/or at the building. On the other hand, it allows for the prediction of the response of new buildings to be constructed close to an existing railway line from vibration measurements in the surface of the ground where the building will be constructed. The VIBWAY toolbox is based on a non-interface 2.5D FEM-SBM approach for the wave propagation on the soil, on semi-analytical approaches for the track and the building and on rigid multibody dynamics modelling of the train vehicle

Double-deck tunnels are an innovative tunnel layout design useful to enhance the efficiency of underground railway transportation systems in which the tunnel is divided into two sections by an interior floor. However, vibration measurements and various recent investigations indicate that train traffic in the upper section of this type of tunnels could induce significantly larger levels of noise and vibration at the nearby residential buildings. This study aims to assess the efficiency of dynamic vibration absorbers (DVAs) as vibration mitigation measures for ground-borne vibrations induced by train traffic in the upper section of a double-deck tunnel. A previously developed semi-analytical model of a track-tunnel-ground system along with a two-dimensional multi-degree-of-freedom rigid body model of the vehicle is employed to compute the vibration energy flow radiated upwards due to a train pass-by. Considering the crucial role of DVA parameters in their efficiency, a global optimisation approach based on a genetic algorithm is used to obtain the optimum parameters of the set of DVAs. The performance of DVAs is assessed for two train speeds taking into account their efficiency in reducing the total vibration energy radiated from the tunnel. The results show more than 6 dB reduction in total radiated energy due to the use of the optimised DVAs

The environmental problems due to ground-borne vibrations induced by underground railway traffic are an issue of growing concern in urban areas as the demand for underground railway network has been increased. The demand gives rise to the construction of more tunnels, faster trains and use of innovative designs for tunnel structure. Double- deck tunnels are one of these designs in which tunnel is divided into two sections by an interior oor. The aim of this study is to assess the efficiency of dynamic vibration absorbers (DVAs) as vibration mit- igation measures for ground-borne vibrations induced by train pass-by in a double-deck tunnel. A previously developed semi-analytical model of a track-tunnel-ground system along with the two-dimensional multi- degree-of-freedom rigid body model of the vehicle is employed to compute the energy ow radiated upwards due to train pass-by. Considering the crucial role of DVAs parameters in their efficiency, a global optimization approach based on a genetic algorithm (GA) is used to obtain the op- timum parameters of DVAs. The performance of DVAs is assessed for two train speeds taking into account their efficiency in reducing the to- tal radiated energy from the tunnel. The results show more than 6 dB reduction in total radiated energy by the use of optimized DVAs

In most of the investigations, the active noise barriers are configured placing both secondary sources and error sensors close to the edge of barriers, but it is unclear how far is this approach from the maximum theoretical performance of the active noise barrier. The purpose of this study is to compare the performance of the active noise barrier when error sensors are on the top edge of the barrier with the maximum attainable reduction at a target zone and then two positions proposed for locating the error sensors which improves the performance of active noise barrier. The maximum achievable reduction at the shadow zone computes when the control sources are 0.5 m far from the edge and along the line which connects the noise source to the edge. The control sources are adjusted to minimize the total squared pressure at receivers placed in the shadow zone. Then the minimization procedure is performed to minimize the squared pressure at the error sensors. The results show poor attenuations when the sound is canceled at the diffractive edge and the new configuration for the error sensors improves the performance of the control system.

Barriers are among the most widely used strategy to control the ambient noise in the urban areas. However, the previous studies approve the inefficiency of the barriers to degrade low-frequency spectra noise. The technique of active noise control (ANC) employs to improve the performance of passive noise barriers at the low-frequency noises. This study seeks to address the effect of employing an active noise control approach on the performance of an infinite barrier. For this purpose, the noise levels at the shadow zone and the neighboring building are measured for three cases, without barrier, with barrier and with active noise barrier. Different locations for control sources and error sensors are investigated to improve the efficiency of the active noise barrier. The results confirm the positive impact of active noise control on the reduction of the noise level in the shadow zone. Furthermore, the distribution of sound pressure levels in the shadow zone helps to define a suitable location for the transducers.

This paper presents a study of the efficiency of isolated concrete blocks as vibration mitigation measures for railway-induced ground-borne vibration problems in subway metro tunnels. The study is performed numerically, using a 2.5D FEM-BEM model of the tunnel-soil system, a semi-analytical model of the track and a rigid multibody model of the vehicle. This comprehensive model of the train-track-tunnel-soil system is used to simulate the vibration response at the tunnel wall due to train traffic for two different track types: a slab track with isolated concrete blocks and a slab track with direct fastening systems. For the slab track with isolated concrete blocks case, various values for the under-block pad stiffness and block mass are considered in the simulation in order to study the effect of these parameters on the mitigation efficiency of this solution. To quantify this efficiency, the criterion used is the insertion loss of the maximum transient vibration value at the tunnel wall for the slab track with isolated blocks with respect to the slab track with direct fastening systems. The results show two important outcomes: on one hand, the mass of the blocks has no significant influence; on the other hand, quite low stiffness of the under-block pads is required to achieve significant vibration mitigation benefits with respect to direct fastening systems

This paper aims to introduce a computationally efficient and user-friendly toolbox, called VIBWAY, able to predict vibration levels that a future railway line, either at-grade or underground, will generate on its nearby buildings or that an existing line will induce on a new building or facility. The VIBWAY toolbox consist of two modules: the first module is based on a semi-analytical approach to model railway infrastructure; the second module is based on a database of pre-calculated tunnel-soil or at-grade track-soil vibration propagation models using numerical methods and employing machine learning approach to make a scoping model. In the first module, different ballasted and ballastless tracks are modelled. The soil is modelled as an elastic layered half-space, and the tunnel is modelled using thin shell theory. It is assumed that near-field dynamic behaviour of the tunnel-soil system is only influenced by the dynamics of the tunnel and the layer that contains it. The train is modelled as a three-dimensional multi rigid body system. A semi-analytical model of the building which considers the three-dimensional nature of the building structure is used. The first module of the toolbox is of great use when the application of vibration countermeasures is required to address the problem of an unacceptable level of vibrations in the buildings close by existing railway lines. It is advantageous as it can be used to assess the performance of vibration countermeasures applied at the track, and/or the building. The second module of the toolbox is more applicable for general scoping studies of new railway lines crossing dense urban cities and it can only present a general overview of the effect of countermeasures applied on the track. This module is not explained here in detail since it is still in development

Modern manufacturers usually need to know at a design stage if their products will meet certain vibro-acoustic requirements. In many cases the use of physical prototyping becomes significantly expensive, and engineers opt for the development of predictive computational models. In these cases, a hybrid deterministic-statistical approach can overcome the challenges that arise when predicting the response of built-up systems in the mid-frequency range. These models, however, may face limitations when complex vibration sources need to be considered. These limitations were recently addressed using a hybrid statistical-experimental model for the case where the vibration sources are directly coupled to statistical components. In this work the approach is extended to the more realistic scenario where the structure of interest contains also deterministic components. The approach is tested in a laboratory case study consisting of a complex vibration source, rigid beams, and a statistical plate receiver. The developed model is validated by comparing the predicted vibration response to the one obtained by experimentally randomising the receiver plate. The results show that a good agreement is obtained for the statistics of the response of not only the statistical plate receiver, but also the deterministic rigid beams. It is concluded that FE-SEA-experimental models can be a suitable tool for predicting the statistics of the response of complex systems
