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.
