Abstract
The paper deals with negative environmental impact caused by the passages of different kinds of trains at variable speed. The study is based on the measurement results which took place in Poland in 2013 on the railway line no. 4. The effect of the traction unit – Pendolino (EMU 250) on the vibration climate was analysed. The impact of passages of new trains was compared to currently operated rolling stock. The speed of trains was varying between 40 and 250 km/h. Vibration measurements were conducted by stuff of an accredited Laboratory of Structural Mechanics at Cracow University of Technology (Accreditation No. AB 826). The influence of the indicated vibrations due to passages of the trains on the building in the neighbourhood of the line was investigated. The vibration assessment was done for horizontal components of vibrations according to Polish standard code. Assessment of environmental impact was presented by indicator of perceptibility of vibration through construction (WODB), which refers to the Scales of Dynamic Influences (SDI scales). The limits specified by standards in any of the passages have not been exceeded. The change of speed or rolling stock resulted in a change in the characteristic of the vibration spectrum.
Highlights
It is not commonly associated with environmental pollution, vibration from roads and railways has a negative impact on the surrounding
Using world literature in the field of mechanical vibration, among others [6,7,8], it can be stated that the issue of vibration excited by trains is an important issue of the modern world
As mentioned in [9], ground vibration limits are exceeded in 44% of assessment
Summary
It is not commonly associated with environmental pollution, vibration from roads and railways has a negative impact on the surrounding. Numerous standards and laws (both Polish [1,2] and foreign [3,4,5]) govern issue of vibration emission. Using world literature in the field of mechanical vibration, among others [6,7,8], it can be stated that the issue of vibration excited by trains is an important issue of the modern world. The problem is increasing in proportion to the increase in train speed and the creation of new high-speed line. Review of over 2300 technical railway vibration papers and holistic vibration prediction (from track to nearby building) we can found in [10]
