VIBROACOUSTIC RAIL DYNAMICS SIMULATION ON SECTIONS WITH BALLAST LAYER
Rails refer to the intensive sources of the acoustic radiation. In rail traffic, rails to a large extent form an acoustic field at the work places of locomotive crews, and in the adjacent residential area nearby the railway track. A considerable extended line source is taken as a noise source model....

| description | Rails refer to the intensive sources of the acoustic radiation. In rail traffic, rails to a large extent form an acoustic field at the work places of locomotive crews, and in the adjacent residential area nearby the railway track. A considerable extended line source is taken as a noise source model. Analytical dependences of sound pressure are obtained. At determining vibration velocities, the rail ballast layer is represented as a partially open-shell profile. It has different inertia moments in the vertical and horizontal planes (OZ and OY), and it lies on the elastic dissipative foundation. The force impact is considered as the load moving along the rail at the speed of the rake traffic. The obtained analytical dependences of sound pressure permit engineering and dissipative characteristics of the rail and ballast layer, and they are base ones for calculating the noise emitted by the rail. Besides, on the basis of the obtained dependences of sound pressure, it is possible to estimate the vibration levels on the rail, and to use the data to solve the problem of vibration impact on the residential buildings located close to the railway track. |
