Tramway Condition Impact on the Vibration Effect

Abstract

Impacts caused by the movement of trams often lead to increased vibration and structural noise in the premises of nearby buildings, which exceed the limit levels normalized by sanitary requirements in accordance with Federal Laws No. 52-FZ and No. 384-FZ. Such impacts are influenced by both the characteristics of the tram train rolling stock itself (speed, weight, condition of structures) and the technical condition of the track structure. Moreover, in accordance with the provisions of SP 441.1325800.2019, the latter can have a significant impact – up to 10 dB with the wear of the structure. The article compares the characteristics of the vibration effect from the movement of trams on the same section for the track under two different technical conditions – before and after the reconstruction, both on a straight section and a curved one. The reconstruction of the track led to a change in the parameters of the vibration caused by the passage of tram trains.
