摘要： PURPOSE: To make the manufacture of a measuring device for irregularity of track which is high in both accuracy and reliability and is easy to calibrate possible by determining the signal corresponding to the difference between the absolute displaycement of the longitudinal level surface of a vehicle body and the relative displacement of the longitudinal level surface between the vehicle body and an axle box and processing the same.
CONSTITUTION: The output of an accelerometer mounted to a vehicle body is double integrated and the absolute displacement rate thereof is obtained. Further, the relative displacement rate between the vehicle body and an axle box is determined by using a relative longitudinal level surface displacement mechanism. Long wavelength components are removed from the signal corresponding to the difference between both by a high-pass filter. For example the displacement of the longitudinal level surface of a rail 1 is the displacement of a wheel 8, that is, an axle box 3, and is converted via arms 13, 15 to a converter 11, by which it is converted to an electric signal. The relative displacement rate between a vehicle body 2 and the rail 1 is determined by this signal. The absolute displacement rate of the vehicle body is obtained by the double integration of the output of an accelerometer 7 mounted to the floor 2' of the vechile body, and long wavelength components are removed from the difference between both displacement rates, whereby the measurement of the irregularity of short wavelength longitudinal level surface of the rail is made possible.

摘要： PURPOSE:To make it possible to measure the stress in the axial direction of a rail, by differentially connecting magnetic anisotropy detecting coils so that disturbance magnetic fields are offset. CONSTITUTION:Detecting coils 17-1 and 17-2 of one magnetic anisotropy sensor 15-1 are cumulatively connected. Detecting coils 19-1 and 19-2 of another magnetic anisotropy sensor 15-2 are similarly connected. When the sensors 15-1 and 15-2 are arranged at an equal angle with respect to a rail, the voltages, caused by disturbance magnetic fluxes, which are induced in the detecting coils 17-1 and 17-2 and 19-1 and 19-2, become equal. When the coils 17-1 and 17-2 and 19-1 and 19-2 are differentially connected, the voltages are offset, and no output appears across output terminals 12. When exciting coils 18-1 and 18-2 are connected out of phase, the signal voltages, which are induced in the detecting coils 19- 1 and 19-2 become out of phase. Since the detecting coils 19-1 and 19-2 and 17-1 and 17-2 are differentially connected, the signals are added, i.e., the result is the twice the original voltage. Therefore, the detected signal of the degree of magnetization of the rail by the exciting coils of the sensors themselves becomes twice the original value. The disturbances are offset, and the proper signal can be positively detected.

摘要： PURPOSE:To measure the shape of a rail top surface with a high precision without being influenced by the inertia or the like of a measuring vehicle by providing the measuring vehicle with a noncontacting gap sensor and running it on the rail to detect the gap and upward and downward accelerations. CONSTITUTION:Wheels 2 are attached to a frame 3 of the lightweight measuring vehicle, and the measuring vehicle is run on a rail 1a. The frame 3 is provided with an attaching plate 9, and a noncontacting gap sensor 11 and an upward and downward accelerometer 12 are attached. The gap sensor 11 is allowed to face the rail 1a to measure the gap. When the reference face of the rail 1a is defined as B at this time, the gap sensor 11 is placed at a height H, and the height H is subtracted from the measured value to obtain a result corresponding to the gap from the rail top surface. Though upward and downward accelerations of the measuring vehicle are changed by the inertia and the natural frequency of the frame, wheels, etc., upward and downward displacement is integrated twice to approximate it to actual displacement. Consequently, since the gap displacement of the gap sensor 11 is compensated by upward and downward displacement of the upward and downward accelerometer, measurement is performed without being influenced by the measuring vehicle neither the wear of the rail.

摘要： PURPOSE:To improve accuracy, of the titled measuring, by detecting and measuring the displacement in right and left directions and change in height based on an eddy current effect, correcting the measured value of the right and left displacements by the height data, thereafter performing the second stage correction by said corrected value and the height data. CONSTITUTION:A signal voltage (v) with regard to a displacement (x) at a height (y) is obtained as an output of a differential amplifier 23 based on the eddy current effects of (x) displacement coils 4a and 4b. Meanwhile, a signal voltage based on the eddy current effect of a (y) displacement coil 8 passes a height operating circuit 24 and a correcting coefficient circuit 25. The result is multiplied by the signal voltage (v) in an analog multilier 26. The corrected right and left displacement values and the height displacement value are converted into the digtal values by A/D converters 27a and 27b. Then, addresses in an ROM are specified. Then, the second stage correction is performed, and the correct displacement amount at the specified address is obtained. In this way, the measurement can be performed without the effect of snow-fall.

CONSTITUTION:The rail replacements (a), (b) based on a vehicle body and the angle phi of revolution of the vehicle body to the reference perpendicular surface of a gyroscope are converted into voltages by a gyro-selsyn 2' while said voltages are converted into digital values by an A/D converter 19. Subsequently, (b-a)/l (wherein l is the segment connecting two points on the side surface of a rail), the angle phi formed by the segment (l) and the long axis of the vehicle body and the angle theta formed by the segment (l) and an absolute reference perpendicular surface are respectively calculated by an operator 20, an operator 21 and an operator 22, and the direction of the perpendicular facing surface at each measuring point on the side surface of the rail is calculated by a moving average operator 25. In this case, operations are performed in synchronous relation to the distance pulse generated at every definite running distance by a pulse generator 33. The angle thetai' formed by the segment (l) and the reference perpendicular surface is calculated by an operator 26 and long wavelength passage ai=ltanthetai' is calculated by an operator 27. The passage ai is outputted as it is and, at the same time, sent to a difference operator 36 and difference DELTAai is calculated and converted into an analogue signal by a D/A converter 31 to be outputted.
