Quasi-static force like unbalanced centrifugal force or turning lateral force acts upon high speed vehicle on curves. At the same time, as vehicles become increasing sensitive to track alignment irregularity or rail joint impulsive force, they are subjected to lateral vibration and lateral force vibration. Many of recent speedup projects involve adoption of tilt train. Then lateral riding comfort and lateral track irregularity growth pose main problems in the field of track maintenance. We report on estimation method of vehicle vibration and lateral force on curves and setting method of track alignment target value, considering riding comfort and lateral force.
