“…In fact, since the early 1970s, work has been underway to develop theoretical models for railway noise, to validate these models against full-scale running tests and to use the models to aid in the design of quieter trains. Remington (1976aRemington ( , 1976bRemington ( , 1987aRemington ( , 1987b produced the first theoretical model of rolling noise, which was developed further and extended by Thompson (1990Thompson ( , 1993aThompson ( , 1993bThompson ( , 1993cThompson ( , 1993d. Subsequent research funded by the European Rail Research Institute (ERRI) resulted in the implementation of the prediction model in a computer program, TWINS (Track-Wheel Interaction Noise Software).…”

Abstract. In this study the virtual prototyping is used for evaluation the influence of the contact roughness upon the acoustic behaviour evaluation of railway monobloc wheel. The proposed procedure covers requirements of the European Standard EN 13979-1 "Wheels and bogiesMonobloc wheels". The main advantage of the acoustic assessment based on the virtual engineering technics -absence of the expensive and time consuming physical tests, is sown. The real industrial-project example is presented and comparison of the numerical and experimental results is used for acoustic behaviour assessment and approval of railway monobloc wheel design.Keywords: virtual prototyping; finite element analysis /FEA/; railway wheel acoustic behaviour.

“…However, in such a simplified model, valid frequency range is very limited. Therefore, Remington, in subsequent work [5,6], used the Love's ring theory to build a wheel model in which the wheel tyre was regarded as an elastic thin ring, the web was simplified as springs & Xiaozhen Sheng shengxiaozhen@hotmail.com 1 and dampers, and the hub combined with the axle was taken to be a rigid mass. A relationship between the radiation efficiency of the wheel and frequency was obtained by fitting experimental data.…”

Vibration and sound radiation of a rotating train wheel subject to a vertical harmonic wheel–rail force

et al. 2018

The rapid development of high-speed railway networks requires advanced methods for analysing vibration and sound radiation characteristics of a fast rotating train wheel subject to a vertical harmonic wheel-rail force. In order to consider the rotation of the wheel and at the same time increase the computational efficiency, a procedure is adapted in this paper taking advantage of the axial symmetry of the wheel. In this procedure, a recently developed 2.5D finite element method, which can consider wheel rotation but only requires a 2D mesh over a cross section containing the wheel axis, is used to calculate the vibration response of the wheel. Then, the vibration response of the wheel is taken as acoustic boundary condition and the 2.5D acoustic boundary element method, which only requires a 1D mesh over the boundary of the above cross section, is utilised to calculate the sound radiation of the wheel. These 2.5D methods and relevant programs are validated by comparing results from this procedure with those from conventional 3D analyses using commercial software. The comparison also demonstrates that these 2.5D methods have a much higher computational efficiency. Using the 2.5D methods, we study the wheel rotation speed influences on the factors including the vertical receptance of the wheel at wheel-rail contact point, sound pressure level at a pre-defined standard measurement point, radiated sound power level, directivity of the radiation, and contribution of each part of the wheel. It can be concluded that the wheel rotation speed splits most peaks of the vertical receptance at the wheel-rail contact point, sound pressure levels at the field, and the sound power level of the wheel into two peaks. The directivity and power contribution of the wheel are also significantly changed by the wheel rotation speed. Therefore, the rotation of a train wheel should be taken into account when calculating its vibration and sound radiation.

The sleepers supporting the rails of a railway track are an important source of noise at low frequencies. The sound radiation from the sleepers has been calculated using a threedimensional boundary element model including the effect of both reflective and partially absorptive ground. When the sleeper flexibility and support stiffness are taken into account, it is found that the radiation ratio of the sleeper can be approximated by that of a rigid half-sleeper.When multiple sleepers are excited through the rail, their sound radiation is increased. This effect has been calculated for cases where the sleeper is embedded in a rigid or partially absorptive ground. It is shown that it is sufficient to consider only three sleepers in determining their radiation ratio when installed in track. At low frequencies the vibration of the track is localised to the three sleepers nearest the excitation point whereas at higher frequencies the distance between the sleepers is large enough for them to be treated independently.Consequently the sound radiation increases by up to 5 dB below 100 Hz compared with the result for a single sleeper whereas above 300 Hz the result can be approximated by that for a single sleeper. Measurements on a 1/5 scale model railway track are used to verify the numerical predictions with good agreement being found for all configurations.
