RELATION BETWEEN TRACK IRREGULARITIES UNDER TRAIN LOADS AND NO LOAD

Masayuki IKEMORI

Abstract

Track irregularities were measured under train load conditions using a new high speed inspection car, Maya 341. The sizes of the irregularities were compared with the sizes measured under no load conditions with a light weight, Yoshiike type, inspection car. A unique rule connecting measurement under load versus no load conditions could not be formulated. Relationships are established for load versus no load conditions in a mathematical model.
