摘要： PROBLEM TO BE SOLVED: To provide a device for measuring an amount of corrosion in the bottom of a rail, precisely measuring an amount of corrosion in the bottom of a rail even if there is wear in the head of a rail, and to provide a method therefor.
SOLUTION: The method for measuring an amount of corrosion in the bottom of a rail includes the steps of: contacting an ultrasonic probe 12 to the top face of the head of a rail 1 having a head 1a, an abdomen 1b of which the horizontal width of a cross section shorter than that of the head 1a, and a bottom 1c of which the horizontal width of a cross section longer than that of the abdomen 1b; entering ultrasonic waves into the top face of the head vertically, at that time entering slightly diffused ultrasonic waves; detecting jaw-reflection echoes from a jaw 1d equivalent to the lower face of which the horizontal width of a cross section greater than that of the abdomen 1b of the head 1a of the rail and bottom-reflection echoes from the bottom 1c of the rail; determining the space between the jaw and a bottom-reflection source by the jaw-reflection echoes and the bottom-reflection echoes; comparing a measured value L of the space between the jaw and the bottom-reflection source with a reference value L
O ; deciding that there is bottom-corrosion of the rail when the measured value is smaller than the reference value; and determining the amount of the corrosion by the difference ΔL between the measured value L and the reference value L
O .

摘要： PROBLEM TO BE SOLVED: To provide a flaw detecting liquid supply device which appropriately supplies liquid for a flaw detection in a performance of an ultrasonic flaw inspection, and a vehicle including the flaw detecting liquid supply device.SOLUTION: Flaw detection water in a tank 11 flows to an electromagnetic valve 144 of a flaw detecting liquid supply device 14 through an upstream water piping portion 131. Because the electromagnetic valve 144 opens and closes based on an electric pulse drive signal, the flaw detection water intermittently drops into a reservoir tank 141 to be intermittently supplied into the reservoir tank 141. The flaw detection water stored in the reservoir tank 141 is flowed to a discharge portion through a downstream water piping portion 132. Because the flaw detection water is controlled to be constant in the reservoir tank 141, the flaw detection water is constantly supplied from the reservoir tank 141 to the discharge portion and discharged continuously.

SOLUTION: A surface wave probe moves along a rail, as being in contact with the surface of the rail; generates surface waves toward the surface of the rail on the basis of transmission pulse signals; receives reflected waves reflected by a reflection source which can be present in the surface of the rail; and converts them into reception signals. Reception level signals of reflected waves are integrated at the surface wave probe, over a plurality of times of transmissions and receptions in a prescribed section, corresponding to an integrated value and a moved position to each other and to record them. Metal fatigue can be evaluated, on the basis of the integrated value.
