Conclusion of Dependences Specifying the Formation of Acoustic Characteristics of the Movement of Rolling Stock in a Residential Area

Creation of transport machines of increased power, in the designs of which more and more widely used vibration-active organs, leads to increased levels of vibration and noise harmful to operators, and when operating machines in residential areas and to acoustic pollution of the environment. This problem is most acute for rolling stock. The recommendations of the European Union are aimed at reducing the noise of railway transportation directly in the places where it occurs—on the rolling stock and in track structures. First of all, according to the EU, measures to damp noise in the places of its occurrence should be implemented. However, the process of formation of vibroacoustic characteristics is insufficiently studied. In addition to the negative impact of noise of increased level on locomotive crews, drivers, crane operators, environment, it is necessary to create calculation methods, with the help of which it is possible to determine technical characteristics by a set of indicators, including vibroacoustic ones. This article presents the results of theoretical studies of vibrations in the system “wheel - rail - sleeper”. Dependences for determining the levels of vibrations transmitted to the residential area during the movement of rolling stock and cranes on the rail track are obtained.
