Abstract (en)

An inspection apparatus (800) calculates an alignment irregularity amount by substituting angular displacements of wheel sets (13a to 13d) in a yawing direction, state variables derived by a filter, and a measured value of a forward-and-backward-direction force into motion equations that describe yawings of the wheel sets (13a to 13d).
