Abstract
The article deals with a feasibility study methodology for applying vibration insulating mats in tram track construction. The method for calculating railway track vibrations from the rolling stock with axial loads of 220-250 kN/axle at speeds of 50-90 km/h is presented. The dependences of the vibration amplitude obtained are approximated for tram loads, and the performed measurement errors are calculated. Based on the calculations, the dependence of vibration amplitudes on the distance to the tram track for frequencies of 31.5 and 63 Hz is obtained. In conclusion, a recommendation on the use of vibration isolating mats for ensuring acceptable values of the vibration velocity level is given.
