RELATION BETWEEN SUPERELEVATION AND CAR ROLLING

Springs and links between car body and axles can be thought as a mechanical filter to isolate the car body from axle motion (except axle revolution). Then the problem to know the relation between track irregularity and car vibration is the problem to know the characteristics of this filter. there are three methods to study the characteristics. The first method is to calculate the characteristics theoretically from the parts constants. The second method is to know the characteristics by measuring the output of filter for special input. The third method is to determine the characteristics by analyzing the input-output relations for normal operation. No special equipment except measuring instruments is needed. Second, the effect of random noise can be cancelled out by statistical treatment of data. An application of this method is described.
