Lateral Vibration of Railway Bridge-Vehicle System Caused by Track Irregularities |
| |
Abstract: | SUMMARY The lateral vibration of the bridge-vehicle system caused by track irregularities is investigated in this paper by means of frequency spectral analysis method. A railway cable-stayed bridge is taken as the model to study, on which a theoretical analysis is made to compare with the practical results measured. The method proves to be feasible. Then it is applied to studying the interaction between a long-span railway cable-stayed bridge and a freight car as well as the effect of track irregularities on the dynamic characteristics of the bridge-vehicle system, thus leading to a couple of conclusions of considerable significance. |
