Abstract
A system comprising a rail wheel and rail has the wheel and preferably also the rail provided with vibration dampers which absorb vibration having the frequency of the radial resonant vibration frequency of the wheel, for the purpose of preventing the formation of ripples in the rail head's surface on which the wheel runs.
Claims11
In a system for absorbing a rail wheel's radial vibrations, said rail wheel having a rim, an axle hub and a web interconnecting said axle hub with said rim, said system including a plurality of independent vibration absorbers, the improvement comprising:
- a circumferential series of said vibration absorbers forming wheel vibration absorbers circumferentially interspaced along said rim;
- said wheel vibration absorbers being tuned to a radial resonant frequency of said rail wheel induced by said rail wheel's radial vibrations;
- and
- said wheel vibration absorbers being oriented to damp radial vibration.
In a system for absorbing a rail wheel's radial vibration, includes a rail on which a rail wheel is adapted to ride, said rail is supported by conventional railroad ties and is provided with vibration absorbers, the improvement comprising:
- a series of said vibration absorbers forming rail vibration absorbers connected on said rail and interspersed between said railroad ties;
- said rail vibration absorbers being tuned to absorb the vertical vibrations forced onto said rail by said wheel vibrations;
- and
- said rail vibration absorbers being oriented to damp vertical vibrations.
