Abstract
The utility model relates to a rail noise controller and discloses a novel rail noise controller for urban steel rails. The novel rail noise controller comprises a base plate fixed at the bottom of a steel rail and two groups of dynamic absorbers which are respectively arranged on two sides of a rail waist of the steel rail and fixed on the base plate. Damping layers are arranged on the contact portion between the steel rail and the base plate and the contact portion between the steel rail and the dynamic absorbers. The dynamic absorbers are attached to the steel rail. Due to the damping layers middle-high frequency vibration and noise radiation of the steel rail are restrained. By means of the dynamic absorbers, low frequency vibration of the steel rail is reduced. Thus, the rail noise controller is obvious in noise control effect and simultaneously suitable for ballast tracks and ballastless tracks.
