Title: Method for measuring axial force of rail
Inventor: OI SEIICHIRO
IPC: G01L1/00

Abstract: PURPOSE:To directly evaluate the axial force of a rail and to measure local axial force distributions in the rail by fitting an ultrasonic transmitter and receiver to the web of the rail at a prescribed interval and finding the acoustic velocity from longitudinal waves reflected by the opposite surface of the web, and then, comparing the acoustic velocity with a reference value. CONSTITUTION:A transmitter 1 and receiver 2 are fitted to the web of a rail having a constant axial stress at angles of about 14.7 deg. at an interval of about 1m with an ultrasonic wave propagating medium composed of water 3 in between. And, the acoustic velocity V of longitudinal waves is found by repeatedly transmitting pulse waves of, for example, about 0.25musec in width at time intervals of about 1.2msec and only detecting the first waves with gate signals having a prescribed width when about 170musec has elapsed after the transmission, and then, detecting the accurate propagating time of the longitudinal waves from the mean value of the detected first waves. The axial stress sigmaof the rail can be found directly from the difference DELTAV between the previously found reference value V0 of the acoustic velocity (the acoustic velocity of longitudinal waves when the axial stress sigma is zero) and the measured acoustic velocity V based on a formula DELTAV/V0=Ksigma (where, K is an acoustoelastic factor).
