| Abstract |
The article discusses the problem of preventing resonance in bridge beams from the periodic impact of rolling stock. Resonant vibrations of beams occur at high speeds when the train is formed from identical cars. The phenomenon of suppression of beam vibrations by a train is only possible with an exact ratio of the length of the car and the beam, which significantly reduces the set of required beam lengths. In addition, consideration of problems on interaction between a train and a bridge for safety purposes requires the use of a rather complex and cumbersome mathematical apparatus and appropriate software. The article proposes a new method for limiting the vibrations of beams, suitable for any spans and available to engineers at the stage of pre-design assignment of the dynamic parameters of beams. |
