TORSIONAL VIBRATION EVALUATION METHOD FOR RAILWAY DOUBLE TRACK GIRDER

摘要

To not require modeling an individual component.SOLUTION: A torsional vibration evaluation method for railway double track girder includes a step for making a rigid model for analyzing cross-sectional behavior of a railway double track girder, a step for calculating a load allocation rate of each girder by a grid analysis, a step for calculating a rigid of a rotational spring of the rigid model based on the load allocation rate, a step for calculating an eigen frequency rate of the rigid model based on a parameter regarding a torsional rigidity of the girder, and a step for analyzing a dynamic behavior of the railway double track girder when the eigen frequency rate is within a predetermined numeric range.SELECTED DRAWING: Figure 1
