METHOD OF RAILWAY TRAINS VIBRATION CHARACTERISTIC DETERMINATION BASED ON FIELD MEASUREMENTS
The rail transport (railway lines, shallow subway lines or passing on the surface) is a source of increased vibration.As a result,
predicting the parameters of vibration and the structure-borne noise generated by it when designing residential and public buildings near lines or designing new transport lines is an important task. For operating lines, the initial data for the forecast are the results of measurements of vibration parameters at the location of the projected building. For projected lines, the parameters characterizing the source of vibration - the vibration characteristics of moving trains - should be used as the initial data for the forecast. The method for railway trains vibration characteristics determination is described which based on field measurements. As an example of the method application determination of vibration characteristics of commuter trains running along the line of the Savelovsky direction of the Moscow railway is sited. Linear regressions equations are given that connect the weighted vibration velocities in the horizontal direction of vibration propagation perpendicular to the railway line with the train speed.
